My Homey does this now

[L_J]

Obviously it does not work properly any more. If I am lucky I can connect, but that is only temporarily. When I restart it it makes buzzing noice and lightning ring looks like a firework.
Anyone knows what is going on?

Classic symptoms of a broken power supply, time to replace it.

General Stability due to USB Power Supply
Probably the second weakest link of Homey Pro is the USB Power supply delivered with the Homey. Although the relative number of issues could be low, many users have reported Homey restarting many times an hour and giving crinkling noises after months or years working fine. It could start with only restarting once a day. In all Cases that Homey does not keep running: Please lookup another USB Adapter with 5 Volt and at least 2 A (2000 mA), Homey doesn’t use 2000mA but the higher rated USB adapters are usually more stable. In case of doubt regarding inexplicable stability problems, often with unpredicted restarts, please replace the USB Adapter. If the original Adapter is defect create a support ticked at Athom .
(No reason for using the Fast Charge, Quick Charge or Qi as Homey doesn’t use these provide power options)

Just to keep them informed about failing adapters. Maybe you get a new one if you want.
