Hi, i bought Meross MSS210 EU wifi smart plug couple of months ago but i had some issue connecting it to Meross app and I left it a side till now when I integrate it in HA. I see some strange things happening with him, some times it turns off himself and most of the time in the logbook i see that he became unavailable. Do you know what can be the problem ? As general I am very disappointed from this plug …
Even that the plug is in the router room the signal is around 70% most of the time …
Have a very similar issue, did you ever fix this?
No, from time to time i try to make it work but no success even with their app. so i just leave it 
This seems to have randomly stopped happening. It might have coincided with a firmware update on the plugs themselves, although can’t be 100% sure.
