I replaced a Honeywell Wi-Fi thermostat with this because of the periodic unreliability of their cloud network - they do not offer local control of their Wi-Fi thermostats beyond the physical controls so everything else goes through their cloud and it seems to throw errors and be partially or completely down at regular intervals - every week or two. (no, it is not me) Sometimes for a few minutes, sometimes longer. After the last glitch I decided I wanted local control with a different non-Wi-Fi product.
This paired easily (as a secure device, so write down the PIN before you pair) with my Zooz 700 based Z-Wave network and Home Assistant saw it immediately and created appropriate entities. You can either use the internal scheduling feature or turn that off and manage it in your home automation, which is what I did. I have it connected to a C wire (any 24V DC source will work) and it takes 3 AAs as a backup. If your furnace doesn't have a live C Wire you can just create one at the furnace end by breaking out the black wire and using a 24 VDC wall wart power supply.
I would give it 5 stars except that I had wanted to manage it with a separate temperature sensor and there is certainly nothing built in to be able to do that - I'd prefer to override both temperature and humidity sensors externally and expected that would be an included capability - if you are geeky enough to have a Z-Wave network, you probably want your sensors somewhere else, or be able to average a few of them. This doesn't appear to be able to handle that.
I bought this as refurbished and certainly it looked new to me and worked perfectly. A good savings.
