Pairing & Wi-Fi Troubleshooting

Last updated: July 19, 2026

If your Mysa won't pair, keeps disconnecting, or won't join your Wi-Fi network, work through the sections below. For the standard pairing steps, see Pairing Your Mysa for Baseboards.

Thermostat Not Appearing

  • Move closer (within 1–2 meters)

  • Toggle Bluetooth off and back on

  • Close and reopen the Mysa app

  • Check that the thermostat isn't already paired to another account

If the thermostat is linked to another account: if you purchased a used thermostat or moved into a home with existing Mysa devices, it may be linked to the previous owner's account. Contact support@getmysa.com to verify.

Ownership Transfer

If your thermostat is linked to a previous owner's account, request an ownership transfer:

  1. Locate the serial number inside the faceplate — unscrew the screw at the bottom of the thermostat and slide the front cover off

  2. Take a clear photo of the serial number

  3. Email support@getmysa.com with the photo to request the transfer

Pairing Fails Repeatedly

  1. Close the app completely

  2. Soft reboot the thermostat (hold up + down for 10 seconds)

  3. Wait for the pairing icon to appear

  4. Reopen the app and try again

Wi-Fi Connection Fails

  • Confirm you're using a 2.4 GHz network (not 5 GHz)

  • Confirm the network name (SSID) matches exactly — network names are case-sensitive, so double-check capitalization, spacing, and any special characters. If your router shows the name in a settings page, compare it character-by-character rather than relying on memory.

  • Check that your Wi-Fi password is correct

  • Move your router closer or check for signal strength issues

  • Restart your router if needed

Phone Settings for Pairing

iOS:

  • Connect your phone to your 2.4 GHz Wi-Fi network before starting

  • Bluetooth must be ON

  • Location Services must be ON with Precise Location enabled for the Mysa app

  • Local Network Access must be enabled for the Mysa app (Settings > Privacy > Local Network)

Android:

  • Connect your phone to your 2.4 GHz Wi-Fi network before starting

  • Bluetooth must be ON

  • Location must be ON (required for Bluetooth scanning)

  • Wi-Fi Assist or Smart Network Switch must be OFF (can disconnect from Mysa during pairing)

  • Mobile data must be OFF during pairing

  • Battery saver mode must be OFF during pairing

Router Settings

If pairing repeatedly fails, check:

  • Security: use WPA2 or WPA2/WPA3 Transitional (not WPA3 only)

  • MAC Filtering: disable, or add your thermostat's MAC address

  • Band Steering: disable if your router automatically switches devices between 2.4 GHz and 5 GHz

  • Hidden Network: if hidden, try temporarily making it visible during setup

Mesh or Merged Networks

  • Check if your router can separate 2.4 GHz and 5 GHz bands

  • If not, temporarily create a guest network on 2.4 GHz only for setup

  • Some mesh systems (Google Wifi, Eero) work fine — try pairing closer to the main router node

  • After successful pairing, the thermostat stays connected even on merged networks

True Hard Reset

If nothing above works:

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

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

  3. Enter pairing mode — hold up + down on the thermostat for 10 seconds

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

  5. Wait a few minutes for everything to fully boot up

  6. Start fresh in the Mysa app

Network Diagnostics Tool

If you're having connectivity issues during or after pairing, use the built-in Network Diagnostics tool:

  1. Open the Mysa app

  2. Tap Support (top-right corner)

  3. Select Network Diagnostics

  4. Follow the on-screen prompts

This analyzes your network environment and provides recommendations — especially helpful if your thermostat has trouble staying connected or pairing repeatedly fails.
