Exception in Predheat resulted in missed charge for Predbat
Describe the bug Overnight (around 2:45) I appear to have had a network or HA wobble. Predbat tried to grab outdoor temp for predheat and caused an exception and then failed to continue until I restarted Predbat at half 8.
Expected behaviour Gracefully handle an exception
Predbat version
v8.16.5
Environment details
- HAOS

have you got the auto health check automations installed ? The predbat one should detect if predbat stops running for any reason

I haven't no, but will give it a go to help catch it in future runs.
My predbat.status was sat in "Demand" the whole time, although I can't say what the last_updated attribute value was. I'm hoping the last_updated would be what helps catch it.
It was as if the predheat portion was working, but predbat thread had stopped
