I don't see anything about this in the docs. Thanks for reporting.

I also received this warning today after updating to the latest core version of home assistant 2024.8.0

Just replace payload_template: with payload: in your automations/script to remove the warning.

Just replace payload_template: with payload: in your automations/script to remove the warning.

I tried that for when I push my local Tempest temperature into the ESP, and it had worse alarms.

Thank you for saving my sanity....
I had put this down to what was being published to MQTT but obviously (and had I read the actual warning) it is what I am sending to MQTT. It is setting the ambient temperature.

The docs on page 24 just need to be amended from payload_template to payload but not a bug in the code.
