Bosch Ms200 Signal not as MQTT Signal

[linde0815]

I'm usign a Compress 6800 heaet pump witUI800, MM100 an an MS200 Solar Modul

Firmware 3.72 stable

There are sensors TS2 cylinder1 bottom temperature and TS5 cylinder2 bottom temperature.

The signal TS16 is not transmitted. It is connected to TS7 kollectorfeld2 sensor
and is used as cylinder3 bottom temperature . The UI800 uses it but I can't see it as a MQTT entity.

DESCRIPTION

The telegrams 0x362 and 0x363 contains a lot of sensor fields, some are unknown. Please log the telegrams and tell the temperature reported by UI800, Maybe we find the right field.

Hello, first of all, thank you very much for your super-fast response.
Unfortunately, I am currently sick in bed and was only able to respond today.

I did not know that the bus protocol had not been disclosed. Therefore, I made an attempt to improve identification.

I first read the sensor, but this is only possible on the heat pump without decimal places.
Then I cooled the sensor down and it heated up again in the storage tank. Finally, I briefly disconnected it, which should also be visible as a telegram.

I hope that helps.
The temperatures I was able to read [°C]:

53 27 35 28 27

34 36 37 38 41 42 45 46

Then disconnected here

After that, 49°C ..

Ok, it's offset 13 in 0x363. I'm a bit confused how to add this sensor. We have already cylBottomTemp3 as TS11 and collectorTemp2 as TS7. I'll add it as just (TS16) without any other name. Please test https://github.com/MichaelDvP/EMS-ESP32/releases/tag/latest

[linde0815]

That's perfect. Ts7, Ts11 and Ts16 are physically the same hardware input. Only the heat pump turns it into a function, depending on the configuration.

It works!

Many thanks.
