Hello - I've been experiencing regular problems with drop-outs recently on an M5 system (3 units) which I've had in place for just under 2 years. I recently purchased a mixture of generic smart plugs and bulbs and wondered whether they were causing the issue so I've been systematically removing things from the network and testing the results.

However the drop-outs continue. The symptoms are that all 3 units freeze with flashing red lights on them, and eventually reset themselves (with normal wifi service resumed) after about 10-12 minutes. But it's becoming more and more frequent. I've tried rebooting them without success.

Today I updated the firmware to 1.3.1 on them and now I have an additional problem: whilst all units display LEDs at green/working status, I can no longer see the 2 satellite units in my smartphone app (IOS12, iPhone). It only shows the main unit which has an ethernet cable into my modem.

Could anyone suggest what the next steps would be? Starting to tear my hair out on this.
