Check US physical installation requirements

Before you begin

• Exact US hardware variant
• Manufacturer installation documentation

Confirm the latest app screens with the manufacturer. Menu labels can change. Do not enter a Matter QR or setup code on this site.

Pairing steps

1. Match supply voltage and load type, not wattage alone.
2. Verify neutral and single-pole/3-way requirements for switches.
3. Match lock backset, door thickness and bore requirements.
4. Use the thermostat manufacturer’s HVAC compatibility checker.
5. Arrange qualified installation when the existing configuration is uncertain.

Confirm it worked

• Both physical and platform conditions are satisfied

Test the particular function you need. A device appearing in the app does not prove that advanced features, automations or remote control are available.

If pairing fails

• This checklist does not authorize electrical or HVAC rewiring.

• Choose your symptom
• Recheck the device and hub requirements
