Danfoss Ally eTRV automatons and scripts for Home Assistant with Zigbee2MQTT. Tested to work with firmware v1.28(00.28.0008 00.28)
Danfoss Ally has no knowledge of the current time. Zigbee coordinator must send the current time to it. Recommended time update interval is weekly.
1. Create helpers
- Schedule
- Run weekly
- Date and/or time x2
- Use date and time
- Set DST start and end times
2. Import blueprint and create the automation
- 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.
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.
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.
