ZP100 Health Check

Hello.

I am running 10 Sonos players (ZP100's and Connect:AMPs) all hard wired or daisy-chained to my home network. These have been running for a number of years but recently I have had issues with a few ZP100's. Factory resetting sorted one but the other is still causing issues. When I boot it up, I can add it to the Sonos network, it shows up as a room and it will play...for a few minutes...then it drops off the network.

Is there any way to check the health of the ZP100 while it is up and running? I wonder if it is overheating and shutting down? I have just added it again to the network - this time wirelessly - and can see it as a room, etc. I know once I start playing some music, it will drop off again. I have no speakers attached at the moment - just testing that it appears. I have checked for updates - nothing to do there either.

Any help or similar problems incurred is greatly appreciated...
