Pairing Mysa with Apple Home via Matter
Last updated: June 29, 2026
Product: Mysa Smart Thermostat for Central HVAC | Firmware: 4.5.37 or later | App: Mysa app 4.11 or later
This guide covers pairing your Mysa Smart Thermostat for Central HVAC to Apple Home using Matter, what you can do once it is paired, Siri voice commands, and Apple Home–specific limitations. For an overview of Matter and links to other platforms, see Connecting Your Mysa Smart Thermostat with Matter.
Before You Start
Your thermostat, the phone running the Mysa app, and your Apple Home hub must all be on the same Wi-Fi network. If any of these are on a different or guest network, pairing may fail or the thermostat may appear unresponsive.
Mysa Smart Thermostat for Central HVAC with firmware 4.5.37 or later, online in the Mysa app.
Mysa app (iOS or Android) 4.11 or later, signed in.
iPhone or iPad running iOS / iPadOS 16.2 or later.
A Home Hub — HomePod, HomePod mini, or Apple TV 4K. On iOS 18+ you can pair and control locally without a hub, but automations and remote access still require one. iPad is no longer supported as a Home Hub.
Step 1 — Get Your Matter Pairing Code from the Mysa App
These steps are the same regardless of which platform you are pairing to.
Open the Mysa app and tap the menu icon (top left).
Under Other, tap Home Assistants.
Tap Mysa for Central HVAC, then select your device.
On the Connect using Matter screen, tap the Pairing Code field to copy the code, or keep the QR code visible to scan from another device.
Note: Each pairing code can only be used once per platform. If you are adding the thermostat to a second platform, do not return to the Mysa app for a new code — instead, generate a sharing code from the platform you already paired to (see Using Matter with Multiple Smart Home Platforms). The same pairing code can be used again with the same platform if re-pairing is required.
Step 2 — Add the Thermostat in Apple Home
Open the Home app on your iPhone or iPad.
Tap the + button (top right) and choose Add Accessory.
Point your camera at the QR code in the Mysa app, then tap Add to Home.
To pair using a code instead, tap More options → My accessory isn't shown here → Enter setup code… → paste the copied code → tap Continue → tap Add to Home.
Choose the thermostat location when prompted, then tap Continue.
Name the thermostat (the default name is "Mysa Smart Thermostat for Central HVAC").
When the thermostat details are displayed, tap Continue.
Tap Done or View in Home. The thermostat tile now appears in Apple Home.
What You Can Do in Apple Home
Feature | Available | Notes |
|---|---|---|
View current temperature | Yes | Shown on the tile and in detail view |
Adjust heat setpoint | Yes | 7°C – 30°C via Matter |
Adjust cool setpoint | Yes | 16°C – 30°C via Matter |
Heat / Cool / Auto / Off | Yes | All four modes selectable |
AUX / Emergency Heat mode | Shows as Heat | Display only — system is working correctly in AUX mode |
Fan-only mode | Shows as Off | Display only — the fan continues running; use the Mysa app to control fan-only mode |
View humidity | Yes — same tile | Shown alongside temperature in one accessory tile |
Auto mode (dual setpoints) | Yes | Deadband enforced; change the deadband in the Mysa app |
Siri voice control | Yes | See examples below |
Scenes & Automations | Auto mode only | Automations work reliably only in Auto mode (see Limitations); automations require a Home Hub |
Siri Voice Commands
"Hey Siri, set the [room] thermostat to 22 degrees."
"Hey Siri, what is the temperature in the [room]?"
"Hey Siri, turn on heating in the [room]."
"Hey Siri, set the [room] thermostat to cool."
Auto Mode and Deadband
Auto mode lets the thermostat switch between heating and cooling based on your "heat to" and "cool to" setpoints. You can enable Auto mode directly from Apple Home; when enabled via Matter, a default 2°C deadband applies. Deadband control is not available in Apple Home — change the deadband (2°C–6°C) only in the Mysa app, and Apple Home will honour it.
Apple Home Limitations
These come from the Matter standard and Apple's implementation, not from a defect in your thermostat.
Automations Only Work Reliably in Auto Mode
Apple Home automations work correctly when the thermostat is in Auto mode. Automations configured to set Heat or Cool mode separately do not behave as expected — instead of following the automation setpoint, they follow the Auto mode setpoints already configured on the thermostat. Avoid Apple Home automations for Heat or Cool mode; use Auto mode automations, or use Mysa app schedules as a reliable alternative for all modes.
Default Device Name Is Not Unique
Apple Home names every paired thermostat "Mysa Smart Thermostat." If you have more than one, rename each immediately after pairing to avoid confusion.
Device May Stay Online Longer After Wi-Fi Loss
Apple Home may continue showing the thermostat as available for a few minutes after it loses Wi-Fi, longer than Google Home or Alexa. This is normal platform behaviour.
Temperature Range Is Narrower Than the Mysa App
Matter platforms support a heat setpoint of 7°C–30°C and a cool setpoint of 16°C–30°C, compared to 5°C–30°C and 16°C–37°C in the Mysa app. Values set outside the Matter range in the Mysa app display correctly in Apple Home but cannot be re-selected from Apple Home without an error. Use the Mysa app for the extended range.
Re-Pairing After a Reset
Remove the accessory from Apple Home before re-pairing. Then pair again using a new QR code from the Mysa app. Re-pairing the thermostat in the Mysa app disconnects all Matter platforms and requires recreating automations.
