I got my Z-Wave Raspberry Pi setup a few weeks ago, and then spent a ton of time setting up my Bedroom Lights, Bathroom Fan+Light, and ordered even more Z-wave hardware. I also started up an RTL-433 server for a yet unfinished project, and about a week later, Home Assistant suddenly reported all of my Z-wave devices offline. Home Assistant was unable to connect to the WebSocket of ZWaveJS. The Pi was acting really weird.
