It would seem that if we have an adc in the system, we could also program an action or a node red script to shut down the pi when the house battery volts are below a threshold.
If we find a simple USB power bank that offers pass through charging and has enough power for the Pi 3, it would seem that we are there:

The input voltage is only 2A though. Not sure what that would mean in practice. I do like hardware that can be pressed into other uses instead of being only useful with the pi.
Some people have said that the trick is to use a very short cable between the power bank and the Pi 3. I think this may be the solution to my struggles powering the Pi 3 on my existing PSU.
This is pretty clever, using an ethernet switch to trigger shutdown:

Has anyone tried this board?
