Known issue’s

• General Stability due to USB Power Supply
  Probably the second weakest link of Homey Pro 201x (the white ball), 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, or weird zigbee issues. It could start with only restarting once a day.
  In all Cases that Homey does not keep running: Please lookup another decent (from a well known brand) 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
