WEBVTT 00:00.000 --> 00:11.960 Okay, hello everyone, so my name is Benoellicadrono, and I'm working for the main French 00:11.960 --> 00:15.280 DSO, which is called Enedis. 00:15.280 --> 00:23.440 So we are in charge of everything related to low and medium voltage grid in France. 00:23.440 --> 00:31.600 And today presentation is how we make and we use open source in public utilities. 00:31.600 --> 00:36.600 And we did it with the community. 00:36.600 --> 00:41.840 So first slide is about what is Enedis. 00:41.840 --> 00:51.200 Enedis is quite a big company, as you can see we have 16.4 billion euros of volume. 00:51.280 --> 00:59.600 41,000 people, 38 million clients, 1.4 million of kilometers of poll line, and lots of 00:59.600 --> 01:05.520 new stuff like when you're born in Nigeria, electric vehicles, image charging, and everything. 01:05.520 --> 01:12.520 And I think our partners quite particular, because it's not business, a company, as you 01:12.520 --> 01:19.280 said, we are ULTT, so we are state company, and we only do public service. 01:19.280 --> 01:26.400 So our aim is not to make money, is to give a service to people. 01:26.400 --> 01:32.920 And I'm going to introduce you to our smart metal, because it's a subject of today, 01:32.920 --> 01:37.800 which is open source with our smart metal, and our smart metal is this one. 01:37.800 --> 01:43.040 It's calling key, it's a little green, a smart metal. 01:43.040 --> 01:49.160 Smart metal, it's one smart metal, I think I need to go a bit far from simply. 01:49.160 --> 01:55.600 It's one meter by two version, the first version is a single phase metal, and the second 01:55.600 --> 02:03.440 one is a free phase, free phase is a metal, and we did a big rollout, so we installed all 02:03.440 --> 02:12.560 the smart metal between 2015 and 2021, and it was quite a huge project, because we did a 02:12.560 --> 02:20.240 rollout of more than 37 million smarter, Mickey matters, and also with a quite a big budget 02:20.240 --> 02:27.720 four million salesman, and for now it's almost finished, so all our matters are on the 02:27.720 --> 02:35.120 field, and it works pretty well, because we have a nice success rate every day, we have 02:35.360 --> 02:45.800 98% of, yeah, perfect, it's for the camera, I guess, 98% and I'm totally so it's 02:45.800 --> 02:51.720 going to be done, I always take it, 98 generation success rate, so we get the data from 02:51.720 --> 03:02.200 the smart metal every day, and I'm going to explain you what this linking metal does, 03:02.200 --> 03:07.560 on the linking metal we have two interfaces, the first one is quite a simple one, it's 03:07.560 --> 03:16.280 a dry contact, it's a switch, on off switch, and in France we have our hot water tank connected 03:16.280 --> 03:22.600 to this switch, and what it does is when the price of electricity is very low, you get 03:22.600 --> 03:28.880 on a hit, and when it's high, you're going to stop hitting your water, and what is nice 03:28.960 --> 03:36.680 is because hot water tank is kind of cheap battery, you drain energy when the grid needs 03:36.680 --> 03:42.680 it, and you release it, yeah, when you need a shower or anything else, and another interface 03:42.680 --> 03:49.360 is a date and face, that's an interface, I'm going to talk a lot in this presentation, 03:49.360 --> 03:54.480 and we call it the tick interface, why so tick and face is because it's a name of the 03:54.560 --> 03:59.840 protocol, the tick protocol, and it's going to give you all the data you need from your 03:59.840 --> 04:05.840 smart metal, so example you're going to get a tariff padded, so you're going to tell you 04:05.840 --> 04:11.280 if you pay a high price or low price of electricity at the moment, you are also also have also 04:11.280 --> 04:16.560 instantly new power, max power available, energy production if you have some solar panel 04:16.640 --> 04:27.520 and you move a lot of different data, and with this smart metal, we do quite great stuff, 04:27.520 --> 04:36.400 I will say, in France for the grid, and that's a slide about most of the use cases we have 04:36.400 --> 04:43.680 with this link meter, the first one is of course dynamic time of use, so the link meter and the 04:43.680 --> 04:50.240 tick interface is going to say how much you pay, so you are able to drain energy when slow price, 04:51.440 --> 04:58.960 we did also something nice, I think it was four years ago when the Ukrainian war started, 04:58.960 --> 05:07.040 you know the price of electricity was to the sky, and air tea is there here, ask us to do a black 05:07.040 --> 05:14.240 out prevention, and what we did is when you get to contract, electricity energy contract in France, 05:14.800 --> 05:23.520 you ask for a contracted power, so you will tell max power, I need is for example six kva of 3kva, 05:23.520 --> 05:30.800 and what we did is for a very short time during the day, so it was two hours, you get less than 05:30.880 --> 05:38.160 your contracted power, so if you ask for six or nine, for two hours you will only get 3kva, 05:39.840 --> 05:47.600 other use case in energy management, so the temperature of your house will adjust depending 05:47.600 --> 05:54.160 of the time of the day and the price of electricity, and also use case is, I will say contracted 05:54.160 --> 06:02.000 power management, so for example you get 6kva contract contract, and you want an electric vehicles, 06:03.280 --> 06:11.600 the two solution, the first one is you get 9 or 12kva, and the second solution is you get the data 06:11.600 --> 06:17.360 from the smart meter, so you get in start in your power, you get your contracted power, and you 06:17.440 --> 06:24.080 going to start your electric charging vehicle only when you are available power, so for example, 06:24.080 --> 06:31.840 if you have something in the heat oven, the charging station will stop, and the charging of your 06:31.840 --> 06:40.240 vehicle will only start after, and last use case in energy display, so you get an up or you get 06:41.200 --> 06:46.960 display and display going to show you all the data you need, so that's a nice part of 06:46.960 --> 06:53.280 flinky, but we are not here to talk about the nice part, the part we are talking about is what does 06:53.280 --> 07:03.520 work, and what does work is, after 10 years of years of our limcimeter, we are not so quite happy 07:03.520 --> 07:12.960 about, I will say, the use of the tick interface, it's not so, so not so many people use it, 07:12.960 --> 07:19.280 and we were thought about why not people use this tick interface, it's so amazing, you have so many 07:19.280 --> 07:25.600 data you can do, so many use case, but at the end not so many people know about it and use it, 07:27.200 --> 07:36.640 I will give you a quick tutorial on how you can get your tick data, and it's quite simple, 07:36.720 --> 07:42.240 so you get a limcimeter, you get a smart domingo, a small domingo, you open a limcimeter, 07:42.960 --> 07:50.320 you plug in your smart domingo and then success, you can broadcast all your data using a protocol 07:50.320 --> 07:57.760 like Wi-Fi, Ziggy, or much or anything else, so if it's so simple why do people don't do it, 07:58.640 --> 08:09.680 and the quick answer is because of the domingo, the domingo is a problem, so another is this 08:09.680 --> 08:18.000 about the problem on this domingo, the first problem we saw is there is no official domingo product, 08:18.960 --> 08:25.920 so if there is no official product domingo it's not market, so a niche market say high 08:25.920 --> 08:32.640 selling price, but low pollution cost, so don't go, I think it costs to make maybe five euros, 08:32.640 --> 08:38.320 probably more or less if you do more, but if you want to buy it on Amazon or anything else, 08:38.320 --> 08:46.080 you will pay it 60 euros, so it's quite high price just for a domingo, so we can tell but 08:46.080 --> 08:51.120 why and it doesn't sell the domingo, it's because we are not allowed to sell the domingo, 08:51.120 --> 08:58.080 we are a UTT, so public service, so only thing we can sell is one of the state ask us to do it, 08:58.080 --> 09:03.680 and further the goal, so don't go, it doesn't, it didn't ask us to do it, and this is the first 09:03.680 --> 09:10.240 solution to our problem, we are not allowed to sell domingo, but we are allowed to share on open 09:10.240 --> 09:17.520 source on no-lage and we know how to make it, and this is also the one source is also the 09:17.520 --> 09:21.120 problem to the first domingo, there is no official product, but we can make another 09:21.120 --> 09:30.720 and the official open source design out of it, and another problem is the tick interface is quite 09:30.720 --> 09:38.400 difficult to read, it's an AM signal on a 50-year scale, so it may sound simple but we are 09:38.400 --> 09:46.480 very specific constraints on a specification, and all the electronic engineers I saw always 09:46.480 --> 09:56.640 struggle to demodulate, I could explain more, it's quite simple, but the thing is a quick answer 09:56.640 --> 10:06.320 is because we have a very specific requirement as a UTT, is we want the domingo to read the signal 10:06.320 --> 10:14.720 even if the signal is below 1.2 volts, and most people when they make it a normal, they use 10:15.680 --> 10:24.720 piece of hardware called unoptocupular, and this kind of hardware has breakdown, and so it will only 10:24.720 --> 10:33.920 works if the attention is 1.5 volts, and the question is why do we ask 1.2 volts is because on 10:33.920 --> 10:42.960 specific, very specific situation, you will get your piece of equipment very far from your 10:43.040 --> 10:50.000 link meter, so you will get cables between your link meter and the piece of equipment, so it will 10:50.000 --> 10:59.200 happen a voltage drop, and the signal will go below 1.2 volts, and the thing is this specific case 10:59.200 --> 11:04.080 use case case, when you get to the piece of equipment very far from your meter, is only for one, 11:04.080 --> 11:12.480 I will say 0.1% of the clients, and when you are a business company, you don't care about 0.1 11:12.560 --> 11:17.280 percent of the clients, you want to sell products, so you don't care, and so you use unoptocupular 11:17.280 --> 11:25.360 because it's very cheap, then when you are public sales, you care about 0.1% of the clients, 11:25.360 --> 11:33.120 you need to make a product for everyone, so if there is only one client that has a signal voltage 11:33.120 --> 11:40.000 of our sales 0.8 volts, you need to create a product for them, and as a reason why on your market, 11:40.000 --> 11:49.120 you will not find good products, good dongles, but reading a signal of 1.2 volts is quite easy, 11:49.120 --> 11:53.200 if you don't use unoptocupular, but not using this piece of hardware is quite difficult when you are 11:53.200 --> 12:02.080 an electronic engineer, and so I will finish my piece, they are very high energy cost, and 12:02.080 --> 12:10.480 the dongles, most of them, have this design flow using unoptocupular, and again, open source is 12:10.480 --> 12:17.200 a solution, if you share a good design, open source design, they will share the energy cost 12:17.200 --> 12:23.760 between them, and it will help them make this kind of product for the 0.1% of the clients, 12:24.240 --> 12:34.160 and the last problem is there is no smart dongle radio protocol standardized, so everyone 12:34.160 --> 12:41.600 using is unoptocuped, so if you buy the dongle from a manufacturer A, I will say, and you buy 12:41.600 --> 12:48.000 a piece of equipment for a manufacturer B, they won't work together, you have to always buy the dongle 12:48.080 --> 12:57.520 from the same manufacturer, and again, solution, open source, because luckily most of the protocol 12:58.320 --> 13:02.320 you will find in smart home, so I think about the G-Matter e-Bus, our open source, 13:04.560 --> 13:13.200 so we saw that open source is a great solution to our problems, but the question is how do we make 13:13.760 --> 13:24.640 open source? The big part is the hardware part, so we went on GitHub, and we looked for a smart 13:24.640 --> 13:30.560 dongle design, and there are a lot of them, so you have to learn how to write, how to write, 13:30.560 --> 13:39.440 how to write, how to write, all open source, and we found on those design, the same design flow, 13:39.440 --> 13:46.800 so the particular, and when we went on Amazon, we bought some dongles, we found the design to be the same 13:46.800 --> 13:54.560 design, the open source design, so if we want to improve the design, the solution is simple, 13:55.680 --> 14:03.200 is we need to be part of the open source community, and by doing this we will improve all design, 14:03.280 --> 14:08.720 manufacture the one you can buy on Amazon, the one you can find on GitHub, and this is a picture, 14:08.720 --> 14:17.120 so we call all the makers, we bought them to our lab in Paris, and we started to talk with them 14:17.120 --> 14:24.080 to see how we can improve together as a design. The second part is a software part, 14:25.280 --> 14:32.560 this one is hard work, but much simple, the way we did it is we joined the CSA, 14:32.560 --> 14:40.000 so that's a association that is working on Matron Ziggy, and we created a new device type 14:40.000 --> 14:49.200 specific to our method for smart medical, smart dongle, we call EOL, and now if you want to create 14:49.200 --> 14:54.960 a smart dongle using Ziggy, it's quite easy because everything is available on open source 14:54.960 --> 15:03.360 for Matron Ziggy, and we also did something with Ebus, Ebus is a protocol, a German protocol 15:03.360 --> 15:11.600 for energy management at home, and we use an open source stack, we'll modify it so it can 15:11.600 --> 15:17.600 work with our smart metal linking, and now it's quite easy if you buy an Ebus 15:18.560 --> 15:29.440 EV Charlie Station to plug it with a smart metal linking. Finally, this is our open source 15:29.440 --> 15:40.560 roadmap, so in September 2025, we'll use our GitHub to software, the first one is Tick for Ebus, 15:40.720 --> 15:51.440 so yeah, it's a help you charging your EV with your Tick data, second one is a Tick to Web 15:51.440 --> 16:01.600 socket, the third one on October 2025 was the mapping Tick to ZB, we're list, on March 2026 16:02.160 --> 16:09.120 we will release the data, data frame, because we realized we have had a lot of different data 16:09.840 --> 16:14.960 in our lab, so that we didn't share, so it would be just sharing the documentation data, 16:14.960 --> 16:24.160 if we could help people and the modulating Tick interface. In May 2026, we will release 16:24.160 --> 16:31.360 the smart metal, don't go out of our design, and at the end of 2026, or maybe at the beginning 16:31.360 --> 16:43.200 of 2026, we will release the Tick to matter a mapping, and that's the last slide, 16:44.640 --> 16:51.440 the question is what is next, this use case is quite a small use case for specific problem, 16:51.440 --> 16:58.960 the Tick interface, but we have so many different problems, I think we can solve together, 16:59.040 --> 17:06.000 at the end it is all as a European DSL, and when what we see is, we have a lot of thousands of 17:06.000 --> 17:16.560 DSL in Europe, they probably working together at standardization, I think, I ECE or SNLK, 17:16.560 --> 17:23.760 but not a lot of them are working together on open source to create a common solution, and the 17:23.760 --> 17:29.840 thing is, we have all the same problem, we have smart metal, we have grids, we have solar panel, 17:29.840 --> 17:35.920 we have electric vehicles, all we have the same problem, but everyone is solving the problem on 17:35.920 --> 17:43.680 then safe, and if we can work together on a person's solution, I think it's a key to bring 17:43.680 --> 17:50.720 a new technology, open technology in Europe for the grid on the DSL, and that's the question, 17:50.800 --> 17:54.960 where do we start? That's it for me, thank you very much for your attention. 18:01.760 --> 18:03.760 Do you have any question? Yeah. 18:13.120 --> 18:20.080 Yeah, we don't know, because there is no way of knowing it, the Tick protocol is always about casting, 18:20.080 --> 18:27.040 so you don't need to call entities to activate it, so how we know is because we talk a lot with 18:27.040 --> 18:33.280 a manufacturer, a manufacturer of setting don't go, so we know how much they sell, and it's not 18:33.280 --> 18:39.760 solid, or I think it's maybe every year, the sell 10,000 don't go, but when we start in the 18:39.760 --> 18:46.320 Lincoln Protocol, the Lincoln Program, we want everyone to analyze their smart metal data, 18:46.320 --> 18:52.560 because it's a key when you want to do energy management at home, but it didn't work as much as we 18:52.560 --> 18:56.400 plan, so people are using it, but yeah, they could do it more. 18:58.800 --> 19:03.200 Do you plan to get connected to a mass system community, for instance, or sort of to a development 19:03.200 --> 19:14.400 because they are developed? Yeah. Yeah. Yeah, you can already find, find where you get the question? 19:14.480 --> 19:19.760 Yeah, as the question is, do we plan to do open source stuff on our mass systems? Our genome, 19:19.760 --> 19:28.560 I guess, with the Lincoln Meta, we could, but we think it was not our main goal because you can 19:28.560 --> 19:33.920 already find a lot of good open source software for the Lincoln Meta on our mass systems. 19:34.560 --> 19:38.960 So we might one day, but for now, I don't know if you did it, I have your accent, so I guess 19:38.960 --> 19:44.080 you are French and you have a little computer. Yeah, but it's quite, it's quite easy to find some software 19:44.080 --> 19:52.000 to do that already on GitHub. So we did open source only when we felt that the open source solution 19:52.000 --> 20:00.080 was not good enough. Yeah, it's just for you, it's always a question, you know. 20:00.640 --> 20:06.760 Yes, you're a quick question. Can you? 20:23.760 --> 20:29.760 You know, it's a real assistive hot water tank. 20:29.760 --> 20:47.760 So the question is, oh yeah, because you need to hear it, and the mic, okay. I guess it's now. 20:49.760 --> 20:56.760 The question is, what kind of, what's it, what's the time we use if it's a resistive of its heat pump? 20:56.760 --> 21:05.760 And the second question is, when the price of XT is low, and if this price is flexibility. 21:06.760 --> 21:10.760 So the first question is, we use resistive hot water tank. 21:11.760 --> 21:18.760 Maybe one day we will go on a heat pump, but for now it's quite expensive, it's cheaper to get hot water tank. 21:18.760 --> 21:26.760 And if you do it when the price of XT is low, as I said, it's like a battery. So during the night or, yeah, you have a low price, so it's perfect. 21:27.760 --> 21:31.760 And it's quite nice for the grid, for them and the response to have a discount of technology. 21:32.760 --> 21:39.760 And for the second question, yes, the price is low, not at the same time for everyone. 21:39.760 --> 21:44.760 So you have different type of energy construct. 21:45.760 --> 21:54.760 One of them is, it's like dynamic tariff, so 20 days a year, you would have a very high price. 21:55.760 --> 21:59.760 And you will know if you have high price the day before. 22:00.760 --> 22:05.760 So it's usually in during the winter, of course, because once you have the amount of response issue, 22:05.760 --> 22:07.760 but the rest of the time it will be the chip. 22:08.760 --> 22:17.760 And there is also a contract, the price is low only during the night and between during the mid of the day. 22:18.760 --> 22:27.760 And it's not the same for everyone, because imagine if you have low price starting at 9 for everyone, in your neighborhood, 22:27.760 --> 22:32.760 hey, we want to start electric vehicle starting station and hit water track at the same time. 22:33.760 --> 22:37.760 So you will have tension issue, voltage issue in the neighborhood. 22:38.760 --> 22:43.760 So we will change a bit, as the time will change a bit, depending on where you are in your neighborhood. 22:44.760 --> 22:52.760 And it's used also, as best used to this low before at the time. 22:52.760 --> 23:01.760 Now it's small and more with a solar production, so we change the low price to match the high production of solar panels. 23:05.760 --> 23:06.760 Yeah? 23:09.760 --> 23:10.760 Yeah, nice. 23:22.760 --> 23:29.760 The question is, from my knee key, the device, don't be over by the link and I didn't think that's wrong. 23:30.760 --> 23:33.760 So I've already confused something in the way on this. 23:34.760 --> 23:39.760 Is there a way to spy it or use the protocol checking on the borderline? 23:41.760 --> 23:49.760 Okay, yeah, the first question is, it didn't know you can open the link key and to answer this, not always. 23:50.760 --> 24:01.760 Yeah. In most cases, you can open it, but in some cases, for example, if you have some very old cables, paper cables or yeah. 24:02.760 --> 24:13.760 So when you get to the link key, they will, I don't know, I don't have the name in English, but they will, but something, you know, to avoid you open it. 24:13.760 --> 24:21.760 So not always, you have to check if you have a very small piece of green plastic on, yeah, you have the name in French, yeah. 24:22.760 --> 24:32.760 And the second question is, here is an incubator, but down the basement, and I guess you are a flat, it's up in the building. 24:32.760 --> 24:52.760 So how can I use the tick data? It's possible doing it using PLC. We are the solution, a long time ago, that you plug a single on the link key and you plug it on the main on the plug, electric plug, a classic electric plug. 24:52.760 --> 25:06.760 And then you plug a PLC receiver in your flat, and you could have the data, I guess. But we made it a long time ago, but nobody is sending it, there is no manufacturer doing it, making it. 25:07.760 --> 25:21.760 And other solution, you could try using the lower protocol, lower protocol, lower one, you could try. I don't know if it will work, depends of the building, but yeah, we, we made some time, it's quite great. 25:22.760 --> 25:24.760 Let's go through the walls. 25:26.760 --> 25:31.760 Time's up, sorry. And thank you very much.
