Battery Card Display
You can display a device's battery voltage in the app. To enable a battery card
indicator on the data display, go to Settings > Stations > (choose a station) >
Advanced > toggle Enable Battery Card
If you're watching the voltage level (because you are a true weather geek!), it
may appear the Tempest is not charging even when the sun is out. That's
because there is a "start-charge" threshold that must be reached before charging
begins. This prevents the battery from going through a multiple charge cycle "yo-
yo" during the day. Don't worry, that's normal. Every battery is a little different, but
once it starts charging it will continue until the sun is no longer shining or it gets
to a maximum of around 2.7 or 2.8 volts. From there, with no further input, it will
decrease relatively quickly (over a couple hours) to around 2.6v, and then very
slowly from there until the cycle starts again when the sun comes back out. This
is perfectly normal too!
