Inputs stopped working a few days ago. I have checked all services are running, and done a soft and hard reboot.
System information below. Is this something to do with a failed RFM2Pi?
Have you done a controlled power-down and a restart – because the “emon” front end is not restarted when you re-boot the Raspberry Pi.
As Robert says try completely powering down.
Also in the Admin menu, check disk space especially /var/log
