Adding Honeywell T6 Pro Series Z-Wave Therastates to Home Assistant Green

Hardware
1

Can anyone help me understand what I need to do to add my Honeywell T6 Z-Way thermostats to my Home Assistant Green?

2

Buy zwave stick

Install zwavejsui addon

Pair t6 to ha using zwavejsui

3

Totally agree. However there is also Step #4. Set up Automations. The T6 will be integrated into Home Assistant, so you can use the “Climate” actions. Easy peasy.

Thanks. Z-Wave is part of HA green I thought or am I mistaken? Or are you saying even with HA green I will need a zwave stick?

5

Yes. You need to add zwave device. It does not have built in zwave.

Thanks. I purchased a z-wave USB stick but z-wave JS add-on is not starting. Here is what I am getting in the logs:

It is not seeing zwave stick.

Do you have both zwavejsui and zwavejs running? You cannot use both. I prefer zwavejsui.

Trey - You need to add ZWaveJS. Go to Settings/Add-Ons and install it.

TMJ, David - thanks for the assist! It took a couple of times to get is running but it appears to be working.
