IN MQTT a sensor if there is a Firmware upgrade available

Nuki Smart Lock 4 pro


1 binair sensor for the status of the firmware:

  • off= no new firmware
  • on = new firmware


I want to install the firmware when I have the time to check after the upgrade, so I can see if everything keeps working. When there is a update, I install it on one lock and after it is validated and working, then I update the rest.


After the last upgrade 14 feb., MQTT was offline and after reconnecting it is unstable. After the upgrade MQTT was not working, so out lock’s did not respond at all.
This has a lot of impact in the working of your locks and that is very critical.
