something weird has happend… al my deCONZ lights and switches stopped working today… they worked yesterday and they work if I go into deCONZ in HA but none of the buttons in HA work and HA says the states are unavailable… any idea how I can get them talking agan?
Yes that’s the issue , restarting deconz takes some time before lights are loaded and hass loads too quickly. Either restart hass core after some time after a system restart or call the deconz device refresh service
