I miss the status of the valve VS1. This is the valve which switches from Boiler to Solar.
Can someone tell me where to find?

The SM200 have a lot of possible configurations and only a few users have checked the telegrams in their configuration.
I think this valve status could be in telegram 0x36A. Try in terminal read 30 36A, wait for a change of the valve and read again. I guess it is status 03 for off and 04 for on.
If you find it, please also suggest a shortname for mqtt and a fullname for the web dashboard.

BTW: I also miss the flame status. Is there also something available?

A flame in a SM200 is no good, smells like molten plastic.

I can confirm both. 03 for closed and 04 for open valve.

Which byte? The telegram 0x36A looks like this: data: 03 03 03 03 01 03 03 03 03 03 01 03. We know, second byte is pump2, 5th byte VS2, 11th byte pump1, I can add if i know the right position.

For the flame we need motre info from your system and what you've found.

Ok, lucky me, i have already implemented the right offset. Try 3.5.1-dev from https://github.com/MichaelDvP/EMS-ESP32/releases or compile the latest tech-upgrade branch from here.
