Timeout for Older Altherma (EKHBH 11-16kwh) on 0x53 0x55 0x54 got xx/18 bytes

[pitylee]

I have added a new definition file that can be found on my fork but getting these errors:

I can not see a pattern here:

The output you're getting looks like garbage; I can't even see the register ID (0x53/0x54/0x55) anywhere, while it should prefix any reply. You're also getting variable reply length to the same query, which shouldn't happen.

I'd say something's probably wrong on the physical layer.

How?

Are you sure you have common GND between the altherma and the esp32? Can you recheck your cable and provide pictures of the setup?

[raomin]

@pitylee Any update on this one? Did you get your connection ok?

[pitylee]

Hello. Unfortunately not yet. I have ordered new cables, but I think the best would be to have the original socket, which I am unable to find.

i just ordered an esp32 and put espaltherma on it. I have a 2010 version of EKHBH016BA9WN using this definition `LabelDef PROGMEM labelDefs[] = { // 0x50 not supported by EKHBH016BA9WN (no data here for the two values pulled) {0x50, 0, 103, 2, -1, "HP Sensor(kgcm2)"}, {0x50, 2, 103, 2, -1, "LP Sensor(kgcm2)"},

I do not understant the third value (103, 152, 200, 304, 151, 153,...); did not see it anywhere described in the code.

The third indicates which converter to use to transform the bytes into value. See converters.h

Hello andrejb2, did you find in the meantime some additional "values" or "register" which could be useful for an Daikin Altherma version from 2010. I am still testing some of the unclear values. I will keep you updatet...
