Well, not really much change. The CM19 is the most likely problem, I think. After a restart of service, I get about 10-30 sec. of functionality, then it dies. The Cm19 led still does nothing. If nothing else, at least my configuration is staying put. Modules and module labels kept disappearing. Thatnks so much for your help and time.
Yes it's pointing to the CM19 ok. Just one last check. While HG is running again unplug the CM19 and plug it back in again. Copy/paste the following
sudo systemctl status homegenie.service and paste the results.
pi@raspberrypi:~ $ sudo systemctl status homegenie.service
