Re: Problem with OTGW

Thanks Schelte! I had some other things going on, so I wasn't able to look at it for quite some time. I just downloaded it, and will try it out (though with the current weather, the last thing I want now is for my heating to switch on :))

Re: Problem with OTGW

Okay, so I've checked the hardware, and that is okay. I have received another tip on the Domoticz-forum, and that is to try it with an older version of the software. Apparently the software before version 4 was giving less errors in combination with Domoticz. I have checked the website, but I can on...

Re: Problem with OTGW

No, that is normal. If you don't screw the other end of the resistor into X1, no current can run. And so the voltage doesn't drop. You need to connect the resistor between the two X1 contacts. Okay, I'll try that tomorrow then. The Amp part of a multimeter usually has a fuse that can easily be blow...

Re: Problem with OTGW

It looks like domoticz bombards the OTGW with commands without waiting for a response. The OTGW was not designed to handle such abuse. Then at some point it resets. That clears the PS=1 mode and the OTGW starts reporting Opentherm messages again (that is not gibberish, it's valuable data). It may b...

Problem with OTGW

Hello everyone, I'm (as you can see) completely new to this forum, and actually still relatively new to the world of domotica. So if I don't make sense, or if I am missing something obvious, please tell me. I am running a Domoticz-installation (latest stable-version) on a RPi 3, and that has run pro...
