I did not find the corresponding registers in the modbus documentation: https://www.stiebel-eltron.ch/content/dam/ste/ch/de/downloads/kundenservice/smart-home/Modbus/Modbus%20Bedienungsanleitung.pdf

Do you know which ones to pick?

Bit weird that they are in de Service Welt, but not in the Modbus....
Same as the max temperature fields in the Energy dashboard:

I raised this with local Stiebel support. During phone call they confirmed that should be possible to control those values via modbus registers, but asked for description in email and promised they will investigate. Lets see with what they will come back.

Any news from the stiebel eltron support?

[kucerazdenek]

Unfortunately nothing, even I pushed them few times….

One more question, I see that my ISG was updated to version 12.2.3.
Any chance to get those two information from this?

[kucerazdenek]

Hi @pail23 , sorry for bothering, any chance to include at least those two values into integration?

Actual Compressor speed
Inverter Power
Compressor starts (count)

Not sure, could it be this?

Speed + Power

Probably would be good to see also register 36128 (to see if it is what percentage the pump is running at from performance point of view)

Compressor starts

This is how it looks like when switched to German on ISG.

[pail23]

@kucerazdenek The "Verdichterstarts" (modbus register 31) is already implemented. This register is only available for LWZ7LWA heatpumps and not for WMP heat pumps.
Regarding the 361XX registers: Would it be possible for to test with the standard modbus integration if you get the desired values? My heatpump does not provide those registers and therefore I can't test it. Once I get your confirmation that you can read those values and you get the correct content, I can implement it in the integration. Many thanks!

[kucerazdenek]

Hi @pail23 , sorry, have been stuck with some sad things last few months. Would you be able to give me some hint how to scan 361XX registers via modbus integration to test if requested values are provided through them?

[pail23]

Yes, you can used the home assistant modbus integration. There are also modbus apps available on mobile phones. Have a look in play store.

Sure, I tried below, but all three are shown as unavailable (even I tried int16 instead of float16) and for address 36118 (this one must be addressed in different way I am afraid), shows an error in HA log:
