Help with template sensor please :)

Configuration

Yeah it gives me that Unexpected error calling config validator: 'NodeListClass' object has no attribute 'items'

I had that to one side to deal with later (doh!), didn’t realise it would affect the rest of the config loading. Do you know how to diagnose that then please?

comment out your scripts and your automations. It seems to be in one of those areas.
