Device Offline Alerts
Last updated: August 20, 2026
Mysa sends an email if a thermostat has not reported a reading in over three hours. This is different from temperature and humidity Smart Alerts, which are push notifications only.
An offline email can mean:
A power outage at home
An internet outage
The thermostat lost power or Wi-Fi
If the thermostat is offline in the app, reconnect it from Mysa App > Wi-Fi & Pairing.
