Sensors and switches triggering but no action
This happens a few times a night but sometimes the automation and switch actions just don't work. 

All the lights still work if I choose scenes on my phone and the phone registers when I press the switch or trigger sensors, however, the buttons and sensors no longer do anything. For example, pressing the switch pops up on the phone so it knows it's being pressed, however the lights won't respond to it. Likewise with motion detectors showing "Triggered" but no lights turn on.

The only way I can fix it is by rebooting the homebridge server. Does anyone know why this is crashing so often?
