Home Assistant crashes when changing input sensor

[johannes1984]

Hi,

I have the reproducable issue, that when I change the input sensor HA fully crashes. The only way to bring it back is to reboot the VM in Proxmox. Running HA 2024.10.2 and Daily Sensor v2024.10.1

I started the debug mode and then tried the change and got this:

-------------------------------------------------------------------
Daily Sensor
Version: v2024.10.1

most likely the sensors don't provide a value at boot, that's why you are getting this issue. that should not be blocking HA though. You should handle this by adding a delay on update or handle it in your template. This does not have anything to do with HADailySensor AFAIK.

When I tried to edit the daily sensor the first time, HA was running for days, so the value was definetly set.

[jeroenterheerdt]

what's the value the sensors provide and what does the template evaluate to in the Template UI?

The same issue occurs here: when editing a daily sensor, changing the sensor input, and saving, Home Assistant goes offline. I have to reboot Docker to get it back online. Current version: v2024.10.2. Last known working version: v2024.9.1.

Did a bypass edit in the file: core.config_entries pro with backup only.

sensor.master_wohnung_temperatur is a Helper, combining two sensors to one, using arithmetic mean
