RasPi dead but Phoscon still works?

After several power failures, the RasPi no longer starts with Deconz and iobroker and conbee II, not even with a backup SD card. Neither the phoscon app works, nor is a ping to the RasPi successful, VNC is also no longer working. iobroker blockly is not working any more. Deconz is also no longer accessible for Alexa. Nevertheless, the Philips Hue Switch still works, with which I can switch all lamps at once, which I have set up in Phoscon for emergencies. How does that work??

Lol, another miracle.
Here no idea on my side, a device can be on only on zigbee network, and I don’t think the HUE and the deconz have same setting (MAC adress, key and ect )

Sounds like a group binding

@Mimiix Does this mean the group bindings work independent on the conbee II after they are setup by deconz? so f.e. unplugging the conbee II and plug it to a usb power only device would work?

(in between the new raspi arrived and is up and running after inserting the sdcard from the damaged raspi w/o any changes, thanks for the robust programming to dresden-elektronik! And a happy new year to all!)

Yes.

However, not all devices support it. Mostly hue and Ikea. Tuya I haven’t seen doing it.

Ha yes, he is right, in my mind when you have say “HUE” I have understand HUE gateway, haven’t see it was just a switch.
So yes it’s called a bind, the switch is making broadcast requests and all devices that are in the same group will react to it, without the coordinator action.
