[springfall2008]

The error here is that 'charge_limit' in apps.yaml isn't pointing to something that is a number you are getting None instead. What did you set it to?

[mikejreading]

Ah - did I miss something in the set up somewhere? It's currently set to:

  charge_limit:
    - number.sunsynk_set_soc_timezone1 # Inverter SOC time slot1

From the Sunsynk example yaml - did I need to do some more config and actually set that somewhere?
