I currently have my Weatherduino running on the bench displaying battery voltage for the TX unit.
I know that you are constrained by the Vantage Pro2 protocol but I was wondering if you can see a way to report voltage from multiple TX units.
I'm seriously considering running my RX unit from battery on continuous charge to allow logging during blackouts. It would be nice to be able to monitor all of them.
An additional feature could be to have some audible or visible notification on the RX unit or WD unit to alert the user to the fact that either the internal or remote batteries needed charge or replacement.

Any thoughts guys?

Currently the Wireless Display units, can show the power supply voltage for TX unit 0 and TX unit 1, but there isn't any alarm function.

Regarding the RX unit, I think you can get what you want without any hardware or software changes. You may just add a small digital voltmeter display to the output of your battery pack.

For less than 2€, something like this will do the job:

My only problem with a voltmeter on the TX battery is that the TX unit is not that accessible for reading.

The suggested idea of the voltmeter is not for the TX units. For these, you can monitor the battery voltage at the WD unit.
Look at the picture below:

Good point.

A quick question. Is the voltage reported by the #battery web tag in Cumulus the RX supply voltage or the TX unit supply voltage.

Is the battery voltage of the TX unit 0
