Pairing Fails Repeatedly

Last updated: October 28, 2026

If pairing fails again and again, do these steps in sequence.

Steps

  1. Connect your phone to your 2.4 GHz Wi-Fi network. Mysa connects to 2.4 GHz Wi-Fi only. Mysa does not connect to 5 GHz Wi-Fi.
  2. Copy the Wi-Fi network name and the password from the Wi-Fi settings on your phone. Paste them in the Mysa app. This prevents typing errors.
  3. Close the Mysa app fully. Do not only minimize the app.
  4. Reset Mysa to start pairing again:
    • V2, Lite and V1: Hold the up arrow and the down arrow for 10 seconds. Mysa removes its Wi-Fi, its Apple Home (HomeKit) pairing, its schedule and its settings. Then you must set up Mysa again in the Mysa app.
    • Gen3: Hold the up arrow and the down arrow until the countdown on the screen ends. Gen3 resets its Wi-Fi and removes all its smart home (Matter) connections. Then set up Gen3 again in the Mysa app, and add it to your smart home app again.
  5. Wait for the pairing icon on the screen. Gen3, V2 and Lite show the Bluetooth symbol. V1 shows the Wi-Fi symbol.
  6. Open the Mysa app. Tap +, then tap Add a Mysa.

If pairing fails again

  1. Restart your phone and your router.
  2. Do a hard reboot of Mysa: Turn off the circuit breaker. Wait 30 seconds. Then turn on the circuit breaker.
  3. Do the steps again.
