Mi-light, Chromecast and HEOS devices disconnecting and reconnecting on several times


I’ve a problem with my Mi-light, Chromecast and HEOS devices.
On several times the device is not responding anymore for a couple of seconds/minutes.
When I restart the app, the device is responding ok directly, but after that device is again not responding after couple of seconds/minutes.

Most of the time the device is also responding again without app restart (after some seconds/minutes), but this is not how it should work.

I already tried;

  • a new router
  • replacing the Homey power supply for a 3ampere one
  • make a flow to restart app when device is not responding, but app restarts then almost every 5 minutes.

This is very annoying…
Does some one have some other tips, or maybe better, the solution?
