The problem

Since the last update I do, I have some problems to set hvac_mode on my heaters. There is an error which interrupt all my automation tasks :

Error: type NoneType doesn't define __round__ method

According to the logs, the problem has start with the fix #523 . When I comment the following line, all is working well. https://github.com/iMicknl/ha-tahoma/blob/88bff1c15ec2c48160c0e1da85c4c6155b8a5c26/custom_components/tahoma/sensor.py#L249

I think that is my "Cozytouch Interface" which cause the problem. It's like a heater for Cozytouch but it doesn't have a temperature sensor.

What version of this integration (ha-tahoma) has the issue?

2.12.2

What version of Home Assistant Core has the issue?

2022.2.5

Which gateway / hub do you use?

Cozytouch

Device model

AtlanticElectricalHeater

What was the last working version for you? Or did you just update it?

Since you link to a change from Aug 12, 2021.

Yes I just update it and I didn't get too much care on the logs after that. I don't remember which was the previous build installed.

But my wife was complaining about the heater not working in the morning and I finally catch this error.

Can you include your diagnostic information?

Hi @iMicknl I can't reproduce the problem with the latest release 2.13.0. I think the PR #768 has solved my issue. native_value=lambda value: round(cast(float, value), 2) Thanks for your help
