Values not refreshing

[n-florin]

Hello, I have a BRP069A62 on a EHBH08DAV6 / ERGA08DAV3 heat pump with an external boiler connected via EKHY3PART. The values are retrieved only when reloading the integration. Otherwise I get the following error.

Do you know what could cause this?

Difficult to say why it is not getting new values but what you could try is to change the line and see which sensors are failing in your config folder go to custom_components/daikin_altherma find the file sensor.py and change the line 108 from

return round(status, 2)

to

return None if status is None else round(status, 2)

And then restart the HA. And check the sensors.

I’ve added this change, the errors are gone and the sensors started to update. It looks like I get a value (instead of None) only when a sensor value changes from the previous state. Thus some sensors update every 30 seconds while others every 1-4 hours when there is a change.

If you need more data to better understand this I can help.

I am pleased with how it works now. When I find the time probably I will add some logs and see the data flow. Thank you!
