Wrong decimal interpretation in VERDICHTER HEIZLEISTUNG (. and ,)

[zimbo86]

When VERDICHTER HEIZLEISTUNG contains decimal places, "." is not considerd as decimal marker
A value of 65,529 results in 65529 (65.529)

That is a different issue. Values are supposed to be between 0 and 100 ... what you see is close to uint16_t::max().

looks like this is happening when hot water is being produced:

For the rest of the time it is normal. Two ideas how to fix it ..
1, Ignore everything that is not a response .... 84f42e6
2, Limit the value range of the sensor to [0,100] and drop values that are outside that range

I hope that 1, fixes it. Can you try that?

hmm not really related to hot water in my case..

Will try these fixes and report back, thank you :)

You still use day/night mode, right? Maybe that has an effect 🤷

yes, but day for HC is 10-24:00, Hot Water 10-11:30 and 17:30-20:30

Ok, got it ... it is not "Heizleistung" but "Heizleistung relativ" ... which already states that values can be negative, too.
Fix therefore is:

perfect!
as value turns positiv at 18:00 Uhr this matches exactly.

works like a charm
