Adding a CT101 Z-Wave Thermostat to Home Assistant
— Smart Home
These are the steps I used to successfully pair a CT101 Z-Wave thermostat with my USB Z-Wave stick running with Home Assistant. These steps were not totally clear in the instructions that came with the thermostat, so I wanted to write them down here.
- Put the Z-Wave USB stick into pairing mode; this varies depending on how you are integrating Z-Wave with Home Assistant.
- Press the “Menu” button on the CT101; a “Mate” button will appear under the antennae icon on the touchscreen.
- Press the “Mate” button once; “R1” will appear on the screen.
- Press the “Mate” button again; the thermostat should pair with the Z-Wave stick.
I’ll also mention that once paired with a Z-Wave stick, the thermostat did not run its programmed schedule for me anymore. That was fine because I used Home Assistant to automate the thermostat temperature setting.
