    BE AWARE - THE OPENTHERM GATEWAY APP WILL BE REMOVED FROM THE ATHOM APP STORE SOON

    As the z-wave of my Homey is broken and Athom support makes no effort to fix this, I've decided to take my Homey offline. It is useless in this state, also seen the slow progress of the core development in general.

    With Homey offline I also cannot support my apps and have decided to remove these from the store.

    For now the code is still available on GitHub (without support), so you could do a local install of it.

    Pity it has to come to this. I am a very fond user of your OTGW app!
  • mruitermruiter Member
    Same here Pity, use it every day
  • DieterKoblenzDieterKoblenz Member
    Hmpf, and now I can't use it anymore. Changed the IP of my ser2net box, can connect using putty just fine but the app doesn't find it anymore. Tried to use --run but that only shows "starting otgw"  and no debug messages whatsoever.. 
  • RamonBaasRamonBaas Member
    In 'node_modules/otg-api/index.js' set 'debugOn = true'.

    Thanks, something is definitely wrong but not sure what. Now it seems to update values and insight but the correct values are not saved. Food for tomorrow.

    Hmm I still have the feeling I did something wrong when setting up ser2net after resetting my wireless OTGW... Can't seem to get it working with Domoticz too.. It sends outs values but It doesn't accept incoming values

    Edit: fixed my own stupid config error, but indeed homey 0.10.0 broke this app :(

    Doesn't find the gateway (actually it does, and it received updates) but doesn't say so in the settings page. 
    When adding thermostat it gives invalid capability error 3

    Ok fixed that:

    So.. gone?
  • RamonBaasRamonBaas Member
    Still there: https://github.com/nlrb/com.tclcode.otgw
  • DieterKoblenzDieterKoblenz Member
    And it still works also on 1.0.0 ;)

    Why not put it up in the Appstore?
  • RamonBaasRamonBaas Member
    Version 1.0.0 is available on GitHub.
  • DieterKoblenzDieterKoblenz Member
    Seems to work flawless! 
  • Kay-ArneKay-Arne Member
    This app and the Visonic PowerMax App are back in the App store!! @RamonBaas does this mean you have started working on the apps again? That would be great news!
    I'm currently looking into the OpenTherm Gateway and your app looks amazing, you've really made quite an effort in developing this app and the detailed information provided with it!

    If I choose to buy the parts for an OpenTherm Gateway then this would be my first project of this kind, so I could use some help...
    In one of the forum posts @RamonBaas said "I've replaced the 7805 by a dc-dc converter and included a USR-TCP232-T in the OTG." Is there any information on how you've build it exactly (maybe a shopping list and a tutorial of some kind? ;) )

    I've found the following tutorial, this will get me in the right direction, but not all the way there...

    Is there someone who can explain how to set up this opentherm gateway. I found the gateway on kiwi-electronics (USB en RS232 version) but it seems that you have to made some modifications to this board to connect this to homey. (adding a ethernet connection) What do I need to make this work? 
  • RamonBaasRamonBaas Member
    @Kay-Arne, @HarmLutjeboer You first need to decide what type of interface you want: wifi or cabled ethernet. If you want wifi, you can add an ESP8266. For wired ethernet I can recommend an USR-TCP232-T2. I am still looking for a cheap solution that has both wifi & LAN. Current;y building an OTG with an Onion Omega 2 (which has both) and looking into the Vocore2. SInce these are Linux based, you can let them run ser2net to transfer the serial data over ethernet.

    As you will use the TTL signals, you can leave out the MAX232 and the 4 1uF capacitors (and the 10-pin header).

    Either way, you'll need the 2A transformer (or 2.3A/2.8A in case of the Onion Omega) and the DC/DC converter as part of the OTG partlist.

    If this is all to difficult, you can PM me and I might be able to assemble an OTG for you.
  • kastelemankasteleman Member
    Any progress on the vocore2? Have one  with no use case at this moment
  • RamonBaasRamonBaas Member
    edited April 2017
    No, haven't received my vocore2 yet. But should be straightforward.
    (Guess what just arrived in the mail today :p)
  • Kay-ArneKay-Arne Member
    @RamonBaas. I would like to make it connected by cabled ethernet for stability because I will place the OTG far away from the Wireless access point. I will send you a PM soon ;)

    So, if I'm right..

    Order on conrad:
    Al the thing from the partlist. Left out the max 232, 4x 1uF capacitors, the 10 pin connectorts, and the transformer. Then add the transformer from 2,8 amp and the DC/DC converter.

    Order the (empty) PCB for the open gateway on Kiwi-electronics 

    Order the USR-TCP232-T2 on for ex. Ali Espress.

    Putting it all together won't be a problem for me. After assembling it all, what is then te next step? What needs to be program and how. 
  • RamonBaasRamonBaas Member
    @HarmLutjeboer If you use the USR-TCP232-T2 you can better take the 2A transformer (is lower). You can also leave out the 16 pin IC fitting BTW.

    You'll either need a PIC programmer (e.g. PICkit 3) or buy a pre-programmed PIC.

    Hey,

    I've been using this app for quite some time now and I really like it. Today I deleted all my insights from Homey because it became unworkable and I noticed at OTGW logs every (tiny .xx) change in temperature. 

    Personally I would prefer an option to log temperature every hour or so instead of every change as this means that I have 4 data points in two minutes which really is too much.
  • RamonBaasRamonBaas Member
    There are two options of loggin with the OTG. One is that Homey by default logs values that are available on mobile cards. Each data update sent by the boiler or thermostat is displayed on the mobile card and logged by Insights. You could ask Athom for an option to reduce data points there. The other one is witht the separate app setting, for values that are not displayed. In principle an option could be added to log those less frequently, although I'm not in favour of that. You could throw away spikes or need to start averaging. Should be core functionality if you ask me.

    For the latest info, please have a look at the forum app page.
  • exeldroexeldro Member
    @RamonBaas the forum app page you are refereing too gives me "Discussion not found." at the moment.
    But https://github.com/nlrb/com.tclcode.otgw works for me now.
