These are API errors returned by deCONZ; Homebridge deCONZ just logs these.
The 202 is a typical case of sh*t happens: due to interference (or the light being powered off) deCONZ marks it as unreachable. I think it still should send the Zigbee message, so the light might react, despite the API error.
The 201 could happen if you manage to change the colour temperature from HomeKit while the light is off. Most HomeKit apps will try and turn the light on first, when changing the colour temperature while the light is off. This shouldn’t happen due to adaptive lighting, as Homebridge deCONZ (should) only send the ct
when config/color/execute_if_off
is enabled. It should enable this, when adaptive lighting is enabled, but I’ve seen sometimes that deCONZ doesn’t take this, see https://github.com/dresden-elektronik/deconz-rest-plugin/issues/6710. In that case, best enable execute_if_off
manually (through the deCONZ API, or from the deCONZ GUI).
Many thanks for the explanation.

When I think about it, it is a phenomenon that has occurred after I have changed the Zigbee channel to 25. Does that sound plausible?
I just never experienced the light not responding, so thought it was the Homebridge deCONZ

Very much so. The light could have missed the channel change (e.g. because it was powered off or due to interference) and still try to communicate on the old channel. Changing the channel of an existing Zigbee network is not a good idea, I’m my experience. Resetting and re-pairing the light should make it reachable again.

I have. Most common situations are (I think in order): cutting power to the light, interference (mostly USB-3), bugs in the light firmware, routing issues on large Zigbee network with devices from different (Zigbee stack) vendors.
I get quite a few error messages like these on 2 out of 38 light units. It concerns two devices from Signify and only these two. I have tried removing them and adding them again. But the error occurs sporadically
