Crash and reboot when opentherm bus isn't connected about esphome-opentherm HOT 8 OPEN

Hi @sag3ll0,

You can try the latest version of the code I just published (thanks to the contribution of @fwestenberg)

If it still doesn't work, you would use Command-line Decoder for Strack Trace from ESP8266 (or the Arduino IDE version) to try to reach the code where the error occurs.

I have already tried these changes, the result is the same. It is important to add that I tried the code without connecting to the heater. Perhaps this is the cause of the problems. But this is strange in theory, if there is no data from the opentherm bus, then the application should not crash. In general, when I try with the boiler, everything will stand up clearly.

Hi @sag3ll0,

The code needs a lot of improvements, one of them is this one.

In this case it should continue to work and simply report that there is a connection problem on the opentherm bus.

I have modified the issue title to make it more clear :-)

Hello, I also ran into this problem. I first wanted to flash, check if everything looked ok and then replace my current on/off thermostat module.

Now I was not sure if the code was ok, because the whole ESP8266 hangs.

If this is an issue that can be solved, that would be nice, it will save the next guy half a day of troubleshooting haha.

Hello, there are news about this issue? I've flashed my esp and I would to test the thermostat without connect to Opentherm bus, but it's won't start.
Thanks

This is still a big issue. My Remeha HR heater is compatible with on/off and openTherm. But if the heater does not detect opentherm, it keeps on/off mode. The module crashes as soon as it is not connected. It should wait and retry every 10 seconds or something.

Please advice!

Woops, updated to the newest version, it does not seem to crash anymore. I'll test soon connecting it to the heater.

Yea, confirmed, this issue can be closed.
