Ideally it would be nice to have the battery warning appear maybe 12 hours before the MagTag dies due to low power. That should give plenty of time to notice the problem and recharge the MagTag.

I originally had the warning appear when the battery reached 3.8 volts but that guess is way too high. I think the MagTag has lasted a week so far since the warning appeared. I have a battery testing script running and 3.3 is about the point where the battery drain accelerates so I'll set it there for now but I may lower it some more later when testing is complete.

Would it be possible to include the US EPA Converted measurement?

The endpoint this code uses is going away. The replacement requires the API key to be in a header. I think this means updating to a new version of the MagTag libraries. Has anyone already done this?
