This is my take on the automation to send external temperature to Danfoss Ally TRV. These are my first attempts at creating a blueprint.
It differs from others with:
- ZHA and Zigbee2MQTT variants
- Uses a timer helper to trigger next start (when external sensor does not update for a long time)
- Does not use a delay/restart, as it can cause situation when attribute is not updated too long
- (Zigbee2MQTT only) Automatically detects correct timings based on radiator covered/uncovered setting
To use, you have to create a separate timer helper for each automation created from the blueprint.
For ZHA, you have to set the timer for the correct maximum update interval, according to radiator mode (30 min for covered, 3h for uncovered), and in blueprint input specify the minimum interval (5 min for covered, 30 min for uncovered)

For Zigbee2MQTT you still have to create a separate timer helper for each automation, but you donât have to set the intervals as they are decided automatically based on radiator_covered state. You can also change the covered/uncovered mode, and automation will use new timings on next run.

I hope these are helpful to someone.
