So I cut power to the switch for abotu half an hour, then rebooted the Hubitat. Now the new dimmer has stopped the waterfall of reporting that overloaded the logs and was causing the Severe CPU load.
I am going to have to monitor this closely for a while though...
Does anyone know how to see the current CPU load? The only thing I found must have been for a few software versions ago (no longer there).
This app will provide a lot of stats on the hub, but I don’t think CPU load is one of them. The issue is likely with the memory which the app does track.
