Apple HomeKit

Last updated: October 7, 2026

Apple HomeKit

Connect Mysa to Apple HomeKit to control your thermostats with Siri, the Apple Home app, or HomeKit automations.

Applies to: Mysa for Baseboards (V1, V2, and Lite) and Mysa for In-Floor Heating.

Gen3 is different. It does not use these steps. Connect it through Matter instead: Gen3: Connecting to your Smart Home using Matter.

Connecting to HomeKit

After pairing your Mysa to the Mysa app, connect to HomeKit using the Apple Home app:

  1. Open the Apple Home app on your iPhone or iPad

  2. Tap + then Add Accessory

  3. Scan the HomeKit code on your thermostat, its base plate, or in the Mysa app — its location depends on the model

  4. Assign the thermostat to a room

  5. Follow the prompts to complete setup

Note Your iPhone/iPad and Mysa must be on the same Wi-Fi network during setup.

What You Can Do

Once connected, you can:

  • Control Mysa from the Apple Home app

  • Use Siri voice commands

  • Include Mysa in HomeKit scenes and automations

  • View and control Mysa on your Apple Watch

  • Control Mysa from your Mac

Siri Voice Commands

Check Temperature

  • "Hey Siri, what's the temperature in the [room name]?"

  • "Hey Siri, what's the [room name] set to?"

  • "Hey Siri, what is the humidity in the [room name]?" (Mysa for Baseboards V2 and V1 only)

Set Temperature

  • "Hey Siri, set the [room name] to [temperature]"

  • "Hey Siri, set the temperature in the [room name] to [temperature]"

Adjust Temperature

  • "Hey Siri, increase the temperature in the [room name]"

  • "Hey Siri, decrease the temperature in the [room name]"

  • "Hey Siri, increase the [room name] by [number] degrees"

  • "Hey Siri, decrease the [room name] by [number] degrees"

Turn Off

  • "Hey Siri, turn off the [room name] thermostat"

HomeKit Scenes

Create scenes to control multiple thermostats at once:

  1. Open the Apple Home app

  2. Tap + then Add Scene

  3. Create a custom scene

  4. Add your Mysa thermostats

  5. Set the temperature for each

Example scenes: "Good Morning" (warm up the house), "Leaving Home" (set back temperatures), "Movie Night" (comfortable living room).

HomeKit Automations

Automate your thermostats based on time, location, or other triggers:

  1. Open the Apple Home app

  2. Tap Automation

  3. Tap + to create a new automation

  4. Choose a trigger (time of day, when you leave, when you arrive, etc.)

  5. Select your Mysa thermostats and set the action

Troubleshooting

Mysa not appearing in Home app:

  • Make sure your Mysa is online in the Mysa app first

  • Your iPhone and Mysa must be on the same Wi-Fi network during setup

  • Check that Bluetooth is enabled on your iPhone

HomeKit stops responding:

  • Check that your Mysa is online in the Mysa app

  • Try removing and re-adding the thermostat in HomeKit

  • Restart your HomeKit hub (Apple TV, HomePod, or iPad)

"No Response" in Home app:

  • Your Mysa may be offline — check Wi-Fi connection

  • Try power cycling the thermostat at the breaker

  • Remove from HomeKit and re-add

Removing from HomeKit

  1. Open the Apple Home app

  2. Long-press on your Mysa thermostat

  3. Scroll down and tap Remove Accessory

This only removes the HomeKit connection — your thermostat stays connected to the Mysa app.
