Hard Reset
Last updated: July 23, 2026
If you've worked through pairing, Wi-Fi, phone settings, and router settings and pairing still won't succeed, do a full reset of every device involved.
Steps
Reboot your phone — power it off completely, then turn it back on
Reboot your router — unplug it, wait 30 seconds, plug it back in
Put the thermostat into pairing mode — hold up + down for 10 seconds until the pairing icon appears
Hard reboot the thermostat — turn off the breaker that powers it, wait 30 seconds, turn it back on
Wait a few minutes — let your phone, router, and thermostat fully boot up before continuing
Start fresh — open the Mysa app and begin the pairing process again
Why This Works
Pairing failures are often caused by stale connection state on one of these three devices (phone, router, or thermostat) rather than a hardware fault. Resetting all three together clears out that stale state rather than troubleshooting each individually.
Still Not Working After a Full Reset?
This may indicate a hardware issue rather than a connectivity one. Contact support with your thermostat model and a description of exactly what happens when you try to pair.
