    Nice! Any pictures available?
  • R.chardR.chard Member
    Very interesting, since I also want to register/log the total power usage (also in the future to predict what light/room is still on, simple way to see if someone is already home etc.)
    However I do not have a smart-meter yet, so I also hope
    Something like the “Klik Aan Klik Uit Energiemeter EML-1000” can be supported. Or I just have to upgrade faster :)

    The top picture is the old prototype with a round design. The 2nd and bottom picture is the new PCB.
  • RobinVanKekemRobinVanKekem Member
    Wow, that looks really nice!
    Great work!
  • DaneeDeKruyffDaneeDeKruyff Member
    Yes, that sure looks nice! Can you tell us what the difference is between the 2 pcb's on the last picture? I see the rj45 connector is missing on the top and a spot for a chip.

    i guess one just has pulse inputs and the other also smart meter input. But what are those headers on top with the extra chip.....  hidden Easter Egg
  • ReflowReflow Member
    That really looks promising! Looking forward to the end results. 
  • DaneeDeKruyffDaneeDeKruyff Member
    Well yeah, there's some difference in placement of the parts, but I really can't find the spot the rj connector goes on the top pcb. And I'm pretty sure I don't see a spot for the chip on the bottom pcb....

    @DennieDeGroot ;Great work!

    Yes the top PCB is a totally different product but also intended to use with Homey...
    I will let you guys guess what it is ;)

    Hint: There is already an app for it in the app store.

    opentherm gateway connect...... what did i win...... ? :)

    @DennieDeGroot ; Any news on this exciting project?
  • mruitermruiter Member
    Also very anxious to know how the app will look like.
    Any screenshots available yet ?

    Well, progress is steady but slow. I have been busy with other stuff so I had little time to spend on the project.
    I have been working on the 2nd PCB, which is a OTGW as @mruiter guessed correctly. Both the hardware and software of this print is working :). Then I spend some time on improving the stability of the software that runs on both devices, and also the initial set-up (wifi configuring, etc) and software updates. I think the software is almost ready to receive the "beta" label ;). The one thing left is still to verify some of the hardware of the P1/S0 PCB. Hopefully I will have some time next week to validate this.

    @mrruiter do you mean the Homey app? It think it will be very simple because it uses the Homey cards and graphs so nothing really special going on here. See my last post on the previous page for a impression. As for the software running on the P1/OTGW themselves I included some screenshots. The webpages are served by the P1/OTGW hardware, so no backend or internet connection is needed.

    As I also wanted to get some power readings, I've made a simple app to read the P1 DSMR data (https://github.com/nlrb/nl.dsmr.p1) and one that reads SunSpec data (https://github.com/nlrb/org.sunspec). This allows me at least to log power consumption and power production. Now I still need to couple the two such that I can get the actual power consumption.

  • spoellyspoelly Member
    wow were can i buy this :wink: very interesting!
  • DaneeDeKruyffDaneeDeKruyff Member
    Looks good!!
  • PhuturistPhuturist Member
    Awesome stuff Dennie and Ramon ... :+1: 
  • RamonBaasRamonBaas Member
    BTW: the two apps now 'talk' to each other. Once a DSMR packet is received a request is done to the SunSpec app to read the solar power value. Delay between the two measurements is ~0.5 sec. So gives a good measurement of actual power usage (purple line; red is solar power production).

    The elektor had a nice article about this.
    They used an USR-TCP232-T to get the data to TCP ip from the P1 port.
    Any experience with this? Because i read that the sinal needs to be inverted, but that it is also possible to configure this and no extra hardware is needed.

    Are you going to put the DSMR into an homey app? Or should i install from GIT when i get my converter?

    I do have some experience with this as I'm using a similar device (USR-TCP232-ED2 for P1, Visonic PowerMax and my water meter). Since it is officially a RS-232 signal, I used a max232 (search for 'mini RS232') in front of it - no need to invert. BTW: the new meters have 5V available as well, so you don't need an external power supply.

    I am planning to make the app available in the app store, but that will take a couple of weeks. First planning to enjoy my holidays :smile: .

    Updates available on GitHub.

    Any news / updates???

  • MichaelMichael Member
    Bump :smile:  
  • DennieDeGrootDennieDeGroot Member
    I have made little progress these few months as I am preparing my new house. So after the move I hopefully will have some time to continue the project. The only thing I can report is that the hardware is verified and that the 5 units I currently have are still running stable with a uptime of 60 days.

    Nice work!

    @DennieDeGroot .... Did you move yet.. We could start a gathering with people to help so you have some spare time again to work on HomeyEnergyLink  :D 

    Love to know if you made some more progress  ;)
  • JaxcJaxc Member
    Where can we buy 1 :)
  • WebsterWebster Member
    @DennieDeGroot ; Also a option to select m3 for S1 meter to read water meter

    please pm me as i also want to test a unit P1 port and pulse input for water meter

    Thanks for the good work

    i also have a smd soldering station if you need help
