This week I've had two interesting scenarios.
One a rb411 (4.10)somehow disabled its wireless card. I had to reprogram its frequency etc.
The other, five days later, a 433 (4.6) somehow lost its bridge and I had to set that back up.
Both systems are attached to a solar powered facility. Temp is about 20degrees F on any given day and colder at night. I am working on setting up a voltage monitoring email system as I'm suspecting that with the cold the battery voltage is dropping and causing improper shutdowns on these two radios. (I'm towing the line with the solar charging and not a lot of sun up here now. If I have a cloudy day I've had the bh drop at night) I can see from the log that there was an 'improper shutdown' although I'm not sure what a proper shutdown would be.
The health status gives voltage readings. Is there a way to have the unit safely power off at a certain voltage? But then how would I turn it back on?
I've been using a low voltage disconnect at the battery array to protect the batteries from draining too far but it is a 24volt array and I believe the RB will go down to about 9volts before turning off.
In essence has anyone experienced a similar issue of settings disappearing (possibly due to power drop)?
