Hia, looks like really great work.
A note here, I’ve been having to stop emonhub to free up the UART on the pi for other things, including oem dev. But there’s a problem.
The issue has been that after entering these bash commands:
sudo systemctl stop emonhub sudo systemctl disable emonhub sudo reboot
Upon reboot emonhub is back! I don’t know why. There must be some kind of script running on boot which installs the service file and enables it.
