Encountering a Homekit error?

Are you getting any of the following errors messages when trying to add Mysa to your WiFi network:

"Couldn’t add Mysa-[6 characters]? Home couldn’t connect to this accessory?”

"Couldn't Add Accessory: Home couldn't connect to this accessory"

"Couldn't Add Accessory: Accessory already added"


Step 1)

Turn off WiFi assist as it can interfere with the pairing process.

Launch Settings app > Tap cellular > Scroll down to the bottom of the screen and switch the WiFi Assist toggle to Off.

Launch the Settings app, tap Cellular, and then tap on the on/off switch next to Wi-Fi Assist.

Step 2)

Ensure you have deleted your thermostat from the Mysa App.

Mysa app > tap thermostat > tap settings in the right-hand corner > tap the trash can icon


Step 3)

Ensure you have deleted the thermostat from the Apple Home App.

Apple Home app > tap edit > tap the thermostat you wish to remove > scroll down and tap Remove Accessory



Step 4)

Factory reset your Mysa thermostat (hold down on the up and downs arrows simultaneously for 10-15 seconds). The thermostat should reboot and the smiley face should appear. 

Step 5)

Reboot your Mysa Thermostat by turning the breaker off then back on.


Step 6)

Open the Mysa app and try to add your thermostat to the WiFi network again. 

Once it is paired and you can find it in the main app screen, it may show the disconnected symbol (a red exclamation mark over the Wi-Fi symbol) for roughly 30 seconds and then it will go away on it's own.
