This guide covers pairing your Mysa Baseboard 3 thermostat to Google Home using Matter, what you can do once it is paired, Google Assistant voice commands, and Google Home–specific limitations. For an overview of Matter and links to other Baseboard 3 Matter guides, see Mysa Baseboard 3: Connecting to your Smart Home using Matter.

Before You Start

Your thermostat, the phone running the Mysa app, and your Google hub must all be on the same Wi-Fi network. If any are on a different or guest network, pairing may fail or the thermostat may appear unresponsive.

  • Mysa Smart Thermostat for Electric Baseboard Heaters V3 / Baseboard 3 with the required Baseboard 3 firmware version, online in the Mysa app.

  • Mysa app (iOS or Android) 4.18 or later, signed in.

  • The Google Home app on an Android phone or iPhone.

  • A Matter-compatible Google hub — Nest Hub (2nd gen), Nest Hub Max, Nest Mini, Nest Wifi Pro, or another Matter-compatible Google device.

Step 1 — Make Sure Baseboard 3 Setup Is Complete

  1. Install and complete setup for your Baseboard 3 in the Mysa app.

  2. Open the Mysa app and make sure your Baseboard 3 is online and connected.

  3. Confirm the Matter QR code is available for your thermostat after setup is complete.

Important: For Baseboard 3, the Matter QR code is ready only after Mysa app setup is complete.

Step 2 — Add the Thermostat in Google Home

  1. Open the Google Home app and tap the + button.

  2. Tap Device.

  3. If prompted, select your home and tap Next.

  4. Choose the option to add a Matter device. Scan the Matter QR code for your Baseboard 3, or enter the setup code manually if available.

  5. Follow the Google Home pairing flow.

  6. If prompted, assign the thermostat to a room and give it a name.

  7. Tap Done. Your Baseboard 3 thermostat appears in Google Home.

Google Home Limitations

These come from the Matter standard and Google's implementation, not from a defect in your thermostat.

Baseboard 3 Is Heat-Only

Baseboard 3 supports Heat and Off through Matter. If Google Home displays other modes, do not use them; unsupported mode commands should not be used.

Tiles May Lag After a Change

Google Home tiles can take a few seconds to reflect changes made in the Mysa app or from another platform. Close and reopen the tile to force a refresh.

May Show Unresponsive Before Mysa App Shows Offline

After a Wi-Fi drop, Google Home may flag the thermostat as unresponsive before the Mysa app shows it offline. This is normal.

Re-Pairing After a Reset

Remove the thermostat from Google Home before re-pairing. Then pair again using the Matter setup flow for Baseboard 3.
