What happens next
Lobby checks batteries every 30 minutes. You get one email per screen and won't be emailed again about that screen until it has been charged. The takeover notice clears itself as soon as the screen is charged.
Tips
- On every plan, the Overview page already tells you when screens need charging soon, and the table view on Screens shows each screen's battery.
- For self-hosted screens, Lobby estimates the percentage from the battery's voltage.
