This web page summarizes all the ANDE telemety trends since launch.

Not only does this reveal neat things about ANDE, but more importantly these plots show how simple it is for just about ANYONE to throw this kind of data together (from ANY device) if the data is transmitted anywhere in the world on APRS. That web page summary took me under 30 minutes to write.
Look at the web page SOURCE and you will see that these data plots are simply CALLS to the global APRS data system at Steve Dimse's K4HG's FINDU.COM data base. This data base maintains every APRS packet in the world ever transmitted (I forget how far back it goes).
But if you have any application that is transmitting APRS formatted telemety packets (any KPC-3+ TNC), anywhere in the world, the data is not only available in real time, but also is avaliable in PAST time too thanks to the FINDU.COM live database.
This means you can throw together a KPC-3+ TNC, a radio, a power source and some 0-5volt sensors, stick it anywhere in reach of the global APRS system, and without lifing a finger, you can monitor it (see above) from anywhere in the world and go back in time to see anything you want. Plug a GPS into it and you can watch it move on APRS too.
This is why we made PCSAT1, PCSAT2, ANDE and RAFT as simply flying KPC TNC's with downlink to the APRS linked ground stations. The telemetry then is a done deal because the global infrastructure is already in place, the data base is in place, and the plotting stuff is all in place.
As an example, this URL call to FINDU.COM will show the battery voltage of my KPC-3+ digipeater over the last 10 days!

To see the same plots from your KPC-3+ TNC, just put it on the APRS frequency, simply change the CALL to your KPC-3+ and/or change the "last=240" parameter to any time period you want, and you can see your own telemetry, anywhere, anytime. Of course your KPC-3+ TNC has to have been beaconing telemetry (see the TELEMETRY Beacon command).
Anyway, I don't think everyone is aware how simple this stuff is. SO I just thought I would share it.
