Danfoss Ally Home Assistant automations & scripts

Danfoss Ally eTRV automations and scripts for Home Assistant using Zigbee2MQTT. Tested to work with firmware v1.28(00.28.0008 00.28).

Time updater automation

Danfoss Ally has no knowledge of the current time. Zigbee coordinator must send the current time to it. Recommended time update is on weekly interval.

Note!

• The script will automatically set DST helpers to last sunday of the current year and the helper's month. Please raise an issue if this is a problem for you.

Weekly schedule script

Note!

• The weekly schedule is lost after power cycle or OTA or error state.
• HA DST start helper will convert set time to the new local time. E.g. 31/03/2024 03:00 --> 31/03/2024 04:00. For now fix by setting the time minute before DST start time e.g. 02:59.

External temperature sensor automation

Blueprint

Radiator covered = false

Automatically adjust eTRV's own temperature with offset. The external temperature needs to be send at least every 3 hours but no more often than every 30 minutes @ every 0,1K change.

Radiator covered = true

Rely only for the external temperature. The external temperature needs to be send at least every 30 minutes but no more often than every 5 minutes @ every 0,1K change.
