Since i’m running ZHA i started investigating why. First of all, i believe it is interesting to see that ZHA is based on zigpy  which implements all the ZigBee features in a handy python library.

      broadcast_initial_delay: 14400
      broadcast_interval: 14400
      z2m_remote_index: "https://raw.githubusercontent.com/Koenkk/zigbee-OTA/master/index.json"

Don’t forget to restart Home Assistant whenever you change the config. You can enable additional Update providers according to the documentation .

Update of Devices

Attention before proceeding: Please make sure to read the corresponding  section of the manual (especially the warnings).

To kickstart the update, you can go via Settings -> Updates and Refresh the list of updates. THen you can run the update. In the case of the update from 1.1.0.1 to 1.1.0.5 of the Sonoff TrvZB, the update took about 40 minutes per device.
