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

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-Wave Fully works in Hubitat Great design (the base where the wires attached and the main unit that snaps onto that) Detailed instructions for installation Cons: 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)

I needed a new Zwave thermostat after the highly expensive brand one I had started failing with memory errors. I can say this DOES work fine so far (about 4 weeks and counting) with my Simon alarm system. Remember to delete the old thermostat from your system before you unplug it from power if you can. It seems to have all the features I want, is a good size (not giant like some) and seems to be working better than my old one ever did.

I decided on a z-wave thermostat because I didn't want to to add another potential failure point to my smart home. With Wi-Fi devices you have to create a separate manufacturer account and then either use their specific app or connect that account to you smart hub and then it communicates with that device through the cloud. In my case I am using SmartThings to automate and control all of my devices, so having the thermostat connected directly to my hub was preferred. It was easy to pair and has worked flawlessly. It's not as flashy as some of the other (more expensive) thermostats, but if I want to see the weather forecast, I look at my phone, not my thermostat. The only downside is that you can't program a schedule into the thermostat if it's paired to a z-wave controller, which kind of makes sense since you can still accomplish that through automations with your hub. But it seems like it could still be available as an option. Of course you can still walk up to the thermostat and change things manually if you want. I would definitely recommend this thermostat to those with smart hubs that want a direct-connected device.

I bought this to replace the old mechanical thermostat in my RV. I needed total control over heating and cooling to be sure it stayed comfortable for my dog while I’m away. Remote monitoring was also important in the event my heating or cooling failed. I chose this specific model because it will operate on batteries alone with no C wire attached. Because of my application, installation wasn’t straight forward. My gas furnace has just 2 wires, one with 12vdc. The rooftop AC has 4 wires, compressor, fan hi, fan low, and ground. This thermostat doesn’t have a connection for ground so I connected the ground from the AC directly to the RV ground wire. There is also no provision for fan speed in this thermostat so the fan low wire remains unhooked. The two remaining wires connected to compressor and fan on the thermostat. This is working great in my RV. In Auto mode it will call for heat or cooling as needed based on individual set points. I have not tried the schedule function as I have it connected to a z-wave hub. Once connected to a hub the internal scheduler is ignored. Scheduling can then be done through the hub app. I did not already have a z-wave hub so I purchased an exlo atom hub at the same time. This tiny hub plugs into USB power which allows me to keep it powered continuously from the RV 12v. The hub acts as a controller for the devices connected to it and a bridge to WiFi. The app for the hub requires an account but does not require any subscriptions. Once connected to the hub I have access to the thermostat through the hub app on my phone. The app displays the current temp/ humidity and allows changes to temp settings and mode. The hub also has access to all settings and outputs of the thermostat allowing integration with other z-wave devices through scripts and can send notifications. It remains to be seen how long the batteries will last. Battery level is displayed in hub app.

No se pudo usar, se devolvio porque llegaron quebrados

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!!!

It's a nice looking product and I think it has good functionality. However, it is not suitable for the Z-wave frequency band in Europe so I needed to return it. It is intended for use in US/Canada.

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.

It's for the Z-Wave, NOT FOR WIFI connection. The picture is misleading.
