As of Tuesday all of my Zigbee are not working anymore.  
I have 45 Zigbee devices and all where working fine before Tuesday.

In my Android Homey app, all Zigbee devices are trying to connect. (running circle)  
When selecting a device, the message : device unavailable (Aooaraat onbeschikbaar) is displayed.

In the Homey developer tools, under the Zigbee protocol, only the Homey device is present under Node0, so no other devices are present. (Empty list)

Multiple reboots didn’t do the job.

I have a Homey Pro (Early 2019)  
Version 12.3.1

Disc Space 810.36 MB of 1.64 GB free  
Memory 109.93 MB of 1.04 GB free

I need help to get this solved.

Thanks,  
Joop

Hi Joop,

Replace the power unit by a decent _5VDC / 2A minimum_ unit, and restart Homey into recovery.  
In the mobile app, select “Add new Homey” and select your model.  
Follow instructions and wait for the menu option “Full software download” and select it.  
This will install the firmware from scratch, and solved the weirdest zigbee issues.

Nothing of your data will be altered, but I’d recommend to have a recent backup at hand, just in case.

> This option is only for Homey (Pro) models “Early 2016”, “Early 2018” and “Early 2019” so Only the White Ball’s Sometimes you need the extra options, things hidden for normal use, for example: Full Firmware download Complete Reset to sell your old Homey Or maybe you just want to change Homey’s WiFi. There are now a couple of extra options in the mobile Apps, so no need to use an FireFox or Chome Browser with flags enabled to press the Alt- key on your keyboard. Just use your App from no…

Homey 2019 is killing every zigbee chip . They do this after an update lat year or something. Happening to thousands of people. Look up Facebook groups etc. I got hold of an old 2019 and haven’t updated it. Not a problem:)  
A search and you will find many thousands with the same problem. And the guy ms behind homey haven’t said anything. And credit to them. People just buy the new one 🤣  
(I needed the aux output. So it wasn’t a option)
