Pairing Your Mysa Smart Thermostat
This guide walks you through connecting your Mysa Smart Thermostat (formerly Mysa for Central HVAC) to the Mysa app.
Before You Begin
- Thermostat is powered on and displaying the Pairing Mode icon (looks like a Bluetooth symbol)
- Phone's Bluetooth is enabled
- Mysa app installed (App Store or Google Play)
- Your 2.4 GHz Wi-Fi network name and password ready
- Phone is within 1–2 meters of the thermostat
Pairing Steps
1. Open the Mysa App
Sign in to your account (or create one if you haven't already).
2. Add Your Thermostat
- Tap Add Mysa from the main menu
- Select Mysa Smart Thermostat from the product list
- Select No when asked if the thermostat is installed — this starts the configuration flow
- Grant Bluetooth permission when prompted
3. Connect via Bluetooth
- Tap Next while standing near your thermostat
- Tap Identify to confirm you've selected the correct device
- Accept the pairing notification on your phone
- Name your thermostat
4. Connect to Wi-Fi
- Select your 2.4 GHz Wi-Fi network
- Enter your password
- Wait for the connection to complete
Note Mysa requires a 2.4 GHz network. If you only see your 5 GHz network, check your router settings.
5. Firmware Update
After connecting, the app may install a firmware update. Keep the thermostat powered and the app open until complete — this can take several minutes.
If the update fails, you can skip it and retry later from Device Settings.
Success
Once complete, you'll see:
- Your thermostat on the app home screen
- Current temperature and setpoint displayed
- Status shows Online
Troubleshooting
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
Re-entering Pairing Mode
If the Pairing Mode icon isn't showing, hold the up and down arrows simultaneously until the Bluetooth symbol appears.
Pairing Fails Repeatedly
- Close the app completely
- Power cycle the thermostat (breaker off for 10 seconds, then back on)
- Re-enter pairing mode
- Reopen the app — it will detect incomplete setup and offer to resume
Firmware Update Stuck
If stuck for more than 5 minutes, tap Skip and retry later from Device Settings.
