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

  1. Reboot your phone — power it off completely, then turn it back on

  2. Reboot your router — unplug it, wait 30 seconds, plug it back in

  3. Put the thermostat into pairing mode — hold up + down for 10 seconds until the pairing icon appears

  4. Hard reboot the thermostat — turn off the breaker that powers it, wait 30 seconds, turn it back on

  5. Wait a few minutes — let your phone, router, and thermostat fully boot up before continuing

  6. 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.
