Thermostat Junkers FR50 not responding to manipulation commands on HT3 bus #605

Closed Oderik closed 3 years ago

Oderik commented 3 years ago

Bug description My Junkers FR50 thermostat cannot be controlled by EMS-ESP. Commands like temp and mode do not result in an actual change of the thermostat settings.

Expected behavior Commands like temp and mode should change the corresponding thermostat settings.

Can you please do a read 10 165 and read 10 179 and post the output. There are two Junkers variants and maybe this is matched wrong.

Thanks, this thermostat uses telegram 179, i change it in the database.

Oderik commented 3 years ago

Thanks, this thermostat uses telegram 179, i change it in the database.

So is this probably the underlying issue or is it just something additional? 😅

MichaelDvP commented 3 years ago

This is the issue. The setpoint temperature is in byte 7 of 179 (last byte 0x29 = 41 => 20.5°C) You can test with a write to 179: send telegram "0B 10 FF 07 00 79 20" set the setpoint to 16°C

Oderik commented 3 years ago

You are right, it works.

Actually it did not work the first two or three times I fired the command but now the temperature is changed.

Thanks! What do you think how long it will take until a fix is released?

MichaelDvP commented 3 years ago

I add it with the next dev-update. I have some other changes and waiting for proddys feedback. But i posted a test-buid to #599 which also includes the database update.

Oderik commented 3 years ago

Installed your test build and BAM I can control the FR50 from Home Assistant. That's totally awesome, thank you very much!

Should the ticket be closed now then or do we wait for something else like release?

proddy commented 3 years ago

thanks Michael! super quick as usual...

MichaelDvP commented 3 years ago

It's now in the dev build so this can be closed. If you miss other functions feel free to open a new issue.
