Opentherm problem OTGW: random number

[martjah]

Hello,

since a week i have a problem with my OpenTherm gateway but i cannot find any information about it. It worked great for over a year now and i haven't changed anything (except that the Heater has been shutdown last week).

Now i get the following messages:

Can anyone tell me what that means?

It works via Opentherm.exe:

So i have a update, not a solution.

The "random" numbers are not random. It are the Opentherm messages that are the same as in the logging with OTmonitor.exe.



But i do not know why Domoticz cannot handle them. I did also update Domoticz to the latest stable version but that did not solve the problem.

I had the same problem some time ago. From that moment i have set my OTGW aside. So i am also currious whats happening.

I've solved my problem

The OTGW was in an "unknown" state. If you open OTmonitor.exe and push F7, you can see the current mode and switch mode.
I tried switching to Gateway but the OTGW did not respond to that (neither the custom GW=1) command.
So i tried updating the firmware and i had to manually reset the unit, i unplugged the OTGW and plugged it back in and it jumped to "Gateway" mode.
The update afterwards but that's not an issue for me because i did not need to update it.

Right i will also try this soon. I hope my OTGW will work again. Have a lot of trouble with it

I had the exact same issue.

First I tried to solve it this way:
- removed OTGW from hardware tab. (not sure if this was needed, bad thing is, the log is also deleted!!!)
- readded OTGW on hardware tab
- no result.
- deactivated OTGW in hardware tab.

Then:
- removed USB and power from OTGW.
- counted to 10 or 20, can't remember.
- reconnected OTGW
- reactivated OTGW in hardware tab.

Working!
