Honeywell TH6320ZW2003 T6 Pro Series Z-Wave Stat Thermostat &, Smart Home

Works great with Hubitat
When I first ordered this they sent me the wrong one, they sent me the WiFi version. I sent it back and reordered this Z-Wave version again and I got it a few days later. This one fully works with Hubitat and it actually has it’s own driver in Hubitat. If you are replacing an existing thermostat make sure you take pictures of where the wires are attached to the old one. You will not use all of the terminals and you need to make sure the wires go in the correct place otherwise you could mess up your HVAC. The instructions are fairly detailed and can be confusing if you’re not sure what you are doing. I luckily had the instructions for my old one and that helped a lot. I have had this installed on a traditional forced air gas furnace and A/C and now installed it on a heat pump furnace and A/C.It comes with a larger back plate that you can use if needed, I liked the look without the back plate so that’s how I installed it. The wires easily push in to place and once I had them there I mounted the base to the wall. The cover flips up to hide the wires. The main unit pushes onto the base. Once that is all done you need to go through the setup on the device and configure everything and boy can you configure EVERYTHING. The instructions also help out in detailing what each function does and the order of them. You need to make sure you configure it for the type of system that you have. Once that is all done you can go through and test each stage of the system to make sure everything is working how it should. After all of that I connected it to my Hubitat and got it setup in there.Overall this is a great thermostat and works well for controlling almost any kind of system and integrates into your smart house. The hardest thing is installing it and figuring out where each wire goes and making sure you have the switches set correctly and the thermostat configured correctly for your system. Make sure you read and reread the instructions for installation. Once you have it installed though it’s a breeze to control and set schedules and everything.Pros:Z-WaveFully works in HubitatGreat design (the base where the wires attached and the main unit that snaps onto that)Detailed instructions for installationCons:Installation can be difficult (need to make sure wires are all in the correct places, switches set correctly and thermostat configured for your particular system)

Better touch screen and Z Wave than Trane 14942771
I ditched my EcoBee 3 for completely local automation and this is not bad! I had a Trane 14942771 Z-Wave but I wanted a auto cool/heat temperature differential less than 3 degrees, and it won’t let you do that. This one will let you go down to 0 differential in 1 degree increments, but I can’t imagine how that would work… anyway, another thing I didn’t like about the Trane is that it would only report current temp in whole degrees, and this one lets you set it to report tenths like the EcoBee. (To see more fine detail on progress toward the set temp.) I also got indoor humidity back.Over the years I’ve installed a Radio Thermostat wifi, two EcoBees, and the Trane thermostat, and I’ve always laughed at how the first letter of my wire colors match to the terminals, with the exception of C which is brown. This one threw me for a loop at first, I wired it up and set it to cool, and got… heat. I went back and read the wiring diagram and this is the only thermostat that has a different terminal for a single stage heat pump with electric aux heat. So watch out, if you have a heat pump, wire your aux heat to E and not W.I liked the base plate and unique snap on wiring connector, with push terminals instead of set screws like the Trane, and the touch screen is snappy. Lots of configuration options but it is missing one thing that I have only seen on the Trane — it would let you delay compressor on after fan and eliminate the lights dimming. Yeah, I know that’s probably only relevant to 1990s pre-variable speed HVAC like mine, but it was nice to have!I won’t be using the scheduling, I’ll be doing that with the Hubitat and my own software, so I can’t speak to that.

This product works amazingly well with Home Assistant. One caveat, the zwave when on battery power (no C wire) goes to sleep. The fix was easy, send a command to the T6, wait 5 seconds and send again. the first command is ignored but does wake up the zwave. the second command is acted upon. At least through a lot of experimentation this is what I found. It only matters if there is a significant delay between sending commands that the zwave goes to sleep. This solution has worked 100% of the time!!!

This has all the features that you would need in a zwave thermostat. pairing is very easy and the connection is solid. It has auto mode as well but needs to be enabled but going to menu 300 in settings.
