I recently had an issue where the bvm-712 temperature/voltage/power wire fuse holder was loose. It stopped conducting electricity. VRM happily continued to report the last known numbers with no notice whatsoever that the bvm was no longer with us. This was after the battery was topped up during the day so I didn't notice at first. Eventually I scrolled down on my phone and noticed "no data to display" on the graph. I also went into the console and saw the bvm listed and labeled as "not connected".
The VenusOS device and the VRM both know that something is missing, and what that missing thing is. I looked at every item in the alarm lists for the Venus device and the bvm but nothing looks like it will do what I'm looking for. Have I missed anything? How can I set up an alarm for that condition without using additional hardware and building a work-around sensor?
The system consists of:
VenusOS on RaspberryPi, powered by the system
bvm-712
3rd party internet hotspot, powered by the system
3rd party 48v battery (Eco-Worthy 50ah 'stackable')
3rd party all-in-one scc/inverter/charger (EG4 3000, rarely connected to shore/grid power)
