Full local Z-Wave HVAC Control

Introduction

My house has had a Emerson Sensi thermostat for the last 6 or 7 servers. While, this thermostat has served its purpose, and worked reliably (locally), I have had the ongoing issue of having to integrate it into my Home Assistant by using it through the Smart Things Integration. This cloud integration randomly stops working, and does not give very much warning regarding its status.

Normally, this wouldn’t be a huge issue, but, a few years back, I automated my fireplace. So, my fireplace will kick on during the day, to avoid heating the entire house, saving energy. Since, the fireplace bases its temp on the MAIN thermostat located in the center of the house, its important to have somewhat accurate details.

So, I have decided to upgrade both the fireplace, as well as my thermostat, to leverage z-wave.
