Cumulus in there latest beta update has added a tag that displays if the transmitter batteries are ok.  (Davis only)

Here is a link to my simple battery monitoring page.

Hey Miles,
I'm running an older version of Cumulus 1 and it has the battery status in the lower left corner of the display. The other Steve at SoftWx has battery status on his free VPLive program.

I made the battery page so I could check from work on my cell phone at home the Cumulus program work fine also WeatherLink, VPLive I don't use as I have no need to use this program at this time. VWS seem to be stuck with no real improvements (graphic, tags, so on) for Davis Station in a really long time less its a new station that need to be added.

Here what you need parts list
1. roll of bell wire
2. drill to drill hole in house
3. project box with D.C.Volt meter mounted

I wonder if it monitors additional items; solar, soil?
Thanks. Will check it out.

Add a push switch, otherwise it would drain the battery faster than the ISS, and you could be onto something  Laughing

Certainly not in a roll of bell wire of volt meter.  The WL "Alarm and battery" report has all sensors and station voltages.  It is a simple mater to grab the data from that report.

Well you must be using a different ver of WL as mine only give the console voltage and for the station you only get an OK and no voltage values. I built the web page just to monitor if the weather station batteries were working from a remote location and the Ok indication indicator is just fine. As for the console I just run the console in the winter with it plugged in then in the summer I unplug and run on the batteries so maybe that voltage value will be more important.

Can you post an example? Voltages from the non-console batteries would be very interesting, but I didn't think they were in the data passed by the console, AFAIK you can't display them on the console either.

From teh manual:  "Note: If you have a Vantage Pro2 console or Envoy with firmware dated May 2005 or later (or version 1.6 or later), battery status displays for every station and repeater selected in the Set Transceiver dialog box, and for repeater A through the highest repeater selected in the Set Transceiver dialog box. "

To get the batt voltage for other than the console you have to do a bit of fancy footwork.

Bushman,

I have looked through every piece of documentation I can find on the VP2, including VWS docs and have been unable to find the reference you quote above. Can you tell me what manual you are referring to? Also, I did find in one of the Davis Repeater docs a reference to being able to handle up to 4 battery status indications but it appears that is only a OK or Not OK indication and not an actual battery reading. Can you elaborate more on what you are talking about? If you are able to find actual battery voltage for the ISS on a wireless Davis VP2 I am very interested to see how this is done and where it is reported.

NOTE: WL & VPLive do provide actual console battery voltage but only give an "OK" for the remote ISS battery.

Well the only useful info I found when reading through the manuals is if you got the console plugged into the wall is that the battery voltage that is displayed is useless  d'oh! how did I miss that when I read those manuals before I bought that weather station over a year ago.
That's on page 39 or in the pdf its 42 that's the console manual

I suspect that is because when you are using the AC adapter the voltage across the battery actually comes from the adapter and not the batteries themselves. When the AC adapter is removed (or unplugged or when the house power fails) then you would read the true battery voltage. Of course that could also be when you discover your batteries are dead...  Shocked So, perhaps it would be a good idea to periodically unplug the AC adapter and check the battery voltage. That may save you when the power goes out and your in the middle of a storm for which you want to collect data.

Well with the brick plug in it read 4.47 and when I pull the brick it read 4.46. Don't remember if the spec told what the lowest voltage that the console will run at.

IIRC 3.2v is the warning.  It should still operate a  bit below that.
