Your yaml looks fine to me apart from the “_template” as Marc pointed out.
Though I agree the warning could be a bit better worded.
However, as the syntax changes the checks have to change and the warnings accordingly.
It is by definition a moving target
Fingers crossed, it will improve in time
Thanks for the reply. So the templates will be evaluated with just services: ? What about data, is it similar and we dont need to use data_template anymore?
Implementation is progressing but haphazard.
Squeeze everything through config check and see if it complains.
(the config check built into HA is an order better)
Fix issues as they arrise
