Devices stop responding, Z2M requires constant restarts

[jrodrigoferreira]

Hey there,

I'm running Z2M as a Home Assistant addon (latest versions of Z2M, HASS and HASS OS), using the SMLIGHT slzb-06m module, over Ethernet. Hass runs on a VM in a dedicated machine, with plenty of resources. Z2M's addon CPU usage is around 0.5% and RAM around 3%.

I have 24 devices, mostly a a mix of Sonoff and Aqara plugs/sensors/thermostats (see attached image).

The network started out as pretty stable, but now I'm having an issue in which equipment (thermostats, door sensors, power measurements from plugs, etc) keeps reporting status but stops responding to commands (i.e. plugs ignore on/off orders, thermostats ignore setpoints). When the network gets to this state the only thing that fixes it is to restart the addon. Power cycling the SMLIGHT module doesn't fix it, so I think the issue is likely with Z2M. Also, it's not always the same devices that fail. Sometimes some of the plugs keep working. It's rare that every controllable device fails.

It's gotten to the point where I have to restart more than once a day, which is getting quite annoying. Any tips on what the issue might be?

Thanks!
