Apple HomeKit Setup — Mysa for In-Floor Heating

Add your Mysa for In-Floor Heating to Apple HomeKit to control your floor heating with Siri voice commands and automate temperature changes throughout your home.

Requirements

To use Mysa for In-Floor with Apple HomeKit, you'll need:

• iOS or iPadOS device — iPhone, iPad, or iPod touch running iOS 14.3 or later
• Home app — Apple's built-in home automation app on your device
• Mysa account — Active Mysa account with your In-Floor thermostat already added to the Mysa app
• 2.4 GHz Wi-Fi network — Your thermostat must be connected to your home Wi-Fi (HomeKit uses this connection)
• HomeKit-enabled device — Optional hub device (HomePod, Apple TV, or iPad) for remote access and automation

Tip: A HomeKit hub lets you control and automate your thermostat even when you're away from home. Without a hub, you can only control it when you're on the same Wi-Fi network.

How to Add Mysa to HomeKit from the Mysa App

The easiest way to add your Mysa for In-Floor to HomeKit is directly from the Mysa app:

1. Open the Mysa app on your iPhone or iPad
2. Select your In-Floor thermostat
3. Tap Settings (gear icon) at the top right
4. Scroll down and tap Apple HomeKit
5. Tap Add to HomeKit
6. Choose a location (room name) for your thermostat
7. Follow the on-screen prompts to complete setup
8. Your thermostat will now appear in the Home app

Note: You may be asked to assign your thermostat to a room in HomeKit. This helps Siri know which room you're referring to when you give commands.

What You Can Control via HomeKit

Once added to HomeKit, you can:

• Set target temperature — Ask Siri to raise, lower, or set a specific temperature
• Monitor current temperature — View the current floor or ambient temperature from HomeKit
• Include in scenes — Add your thermostat to HomeKit scenes (e.g., "Good Night" scene turns off heating)
• Create automations — Set temperature changes based on time, location, or other triggers
• Use with other HomeKit devices — Combine heating control with lights, locks, and other accessories
• Access remotely — Control your thermostat from anywhere with a HomeKit hub

Important: HomeKit shows temperature control only. You cannot switch between Ambient and Floor temperature modes via HomeKit — use the Mysa app for mode changes.

Siri Voice Commands

Once your thermostat is in HomeKit, you can control it with Siri. Common commands include:

Note: Siri responds to the room name you assigned during HomeKit setup. Make sure your thermostat is assigned to the correct room for accurate voice commands.

Troubleshooting Connection Issues

Thermostat doesn't appear in HomeKit

• Verify your Mysa is connected to your 2.4 GHz Wi-Fi network (check the Mysa app)
• Restart the Home app and try adding the accessory again
• Ensure your iOS device is on the same Wi-Fi network as the thermostat
• Check that your Mysa account is active and the thermostat is properly paired in the Mysa app

HomeKit can't control the thermostat

• Confirm your HomeKit hub is online (check Home app settings)
• Restart your HomeKit hub (unplug for 30 seconds, plug back in)
• Remove the thermostat from HomeKit and add it again
• Check that your Mysa app is fully updated from the App Store

Siri commands aren't working

• Make sure you're using the correct room name assigned in HomeKit
• Check that HomeKit has the latest data by opening the Home app
• Verify the thermostat is responding in the Mysa app (not offline)
• Try rephrasing the command (e.g., "set the floor to 25" instead of "set the floor heating to 25")

Automation isn't triggering

• Verify your HomeKit hub is online and up to date
• Check that conditions in the automation are correct (room, temperature, time)
• Make sure the thermostat is assigned to the correct room
• Test the thermostat manually from the Home app to confirm it's responsive
