How to determine TX battery voltage on a Vantage Vue ISS?

[WindnFog]

Is there a variable that has the ISS transmitter battery voltage available?  Reading the here, and in the documentation, suggests it is a boolean variable.  At least $current.txBatteryStatus seems to be.  I'd like to find something like $current.consBatteryVoltage or equivalent for the ISS.  The hardware is a Davis Vantage Vue.  What does the plot "Remote Sensor Signal Strength" use as the basis for the % axis?  Basically, I want to monitor transmitter battery voltage or some other metric as opposed to just knowing if it is good or bad.

Thanks, Paul

No. There are not.

Battery voltage is not transmitted from the ISS to the console.

Thanks, Jose. I was beginning to conclude that. I was hoping to
get some warning the battery was starting to go, but it's a binary
signal - good or bad. Davis says to expect about 8 months at my
latitude, and it was 7 months old . . . also this during a Canadian
winter. Today I climbed up the 30-foot tower and replaced it. It was
at 2.7 volts as opposed to a little over 3 volts for the replacement. I
was getting the infamous "Low Battery Transmitter 1" console message
recently. I could clear it and wait until midnight for it to reset, but
it was coming back every 5-6 days.

This is typical of what I've observed for the past number of
years. Issue resolved for another 7-8 months. I understand some early
model Davis stations had a hardware issue related to its super capacitor
and/or corrosion, but this is just normal wearing out of the battery.

It might make sense to run 3-volts up there from a ground mounted
power source of some kind, but leaves and the like in the rain collector
generally mean it needs to be inspected a few times a year, anyhow.
