Configurable, Good-Looking Z-Wave Thermostat
I bought this thermostat to use with Home Assistant. I was looking for a nice-looking, fully Z-Wave controllable thermostat, and figured I’d give this one a try even though it’s brand new. I’ve been very pleased with it so far.Installation was a breeze: just disconnecting the wires from my old thermostat, and connecting them to the same terminal. Unlike a Nest, you do have to understand a bit about what kind of system you have to properly configure the software. You need to tell the thermostat what kind of system you have (heat only, cool only, or both, conventional or heat pump, and how many stages). But if you’re moderately familiar with how normal HVAC systems work, it’s not hard to figure out.I scanned the QR code on the side, and the thermostat immediately joined to ZWaveJS via Smart Start as soon as I flipped the breaker back on. After the initial interview process completed, it shows up in Home Assistant properly as a thermostat, with all the controls you’d expect for a thermostat and more. You can even tweak the hysteresis values (how far temperature is allowed to differ from the target before the it calls for heating or cooling), set extra run time for the fan, and change the temperature offset to manually calibrate the sensor. All very nice. Out of the box, the temperature and humidity sensors seem well calibrated.Looks-wise, it’s a fairly sleek, unobtrusive design, especially when the screen is off. Not quite as polished as a Nest thermostat, but it looks nicer than any other Z-Wave thermostat I looked at.My one complaint is that the way schedules are defined, if you’re using local scheduling, is poorly documented in the manual. The thermostat has two sets of configuration parameters for setting a local schedule, one a “simple” schedule that applies for all 7 days in a week, and a second set of fine-grained parameters to set a separate schedule for each day. It’s not at all clear which set of parameters takes precedence when, and it took me a couple of days of back-and-forth emails with tech support to get a good answer. It turns out they use the Z-Wave configuration “default” flag in a very unusual way: the fine-grained parameters are ignored if the default bit for the parameter is set, even though the default parameters make a sane-looking schedule.The best practice is probably to set all the parameters for one schedule type or the other, and explicitly default the other set. Or, more flexibly, leave local scheduling off and control your thermostat from your Z-Wave hub.I will say I was impressed with the manufacturer’s tech support rep’s willingness to engage over minute details in the implementation. It would have been easy for them to say “you’re not using our hub, so we’re not going to help you,” but that wasn’t the response at all. Big thumbs up.I’ll update this review if I experience any issues with long-term reliability, but initial impressions are very positive. If you want a Z-Wave thermostat, this is a great choice.

Random relays stuck on. Manual is a mess.
Like another reviewer, I purchased this thermostat to use with Home Assistant. The device looks nice and boasts Z-Wave 800 Series connectivity. Unfortunately, the product worked so poorly as a thermostat that I decided to return it before ever testing its Z-Wave functionality.When turning on power to my HVAC system at the breaker box, the thermostat randomly turned on some combination of blower, furnace, and/or AC compressor, regardless of what mode the thermostat was in. Whichever relays were stuck on remained on, even after changing the thermostat to a different mode. It was truly strange to see my thermostat claim to be OFF … while it was running the AC and furnace simultaneously! I was able to get the thermostat to behave temporarily by performing a factory reset, but by the next day, the fan relay was stuck on again. My testing showed that a power outage or even just removing the thermostat from the wall (for a battery change) would re-trigger the problem every time. My HVAC system is not special; it’s a conventional one-phase heat/cool system with R, G, Y, and W wires â probably the most common type in the US. And I’m 110% sure I identified my four wires correctly. It’s not rocket science.Another review mentions “both heating and cooling running when set to cooling”. I’m pretty sure that person experienced the same pathological behavior that I did. Who knows, maybe I received the thermostat they returned.Then there’s the manual. It’s poorly organized, with information presented out of order, duplicated, or omitted. The installation instructions tell you to snap the thermostat onto its wall bracket BEFORE attaching the wires to the wall bracket, which is physically impossible. The manual does not say when to turn the power back on. The steps for removing the old thermostat appear after the steps for installing the new thermostat. The all-important table of system types appears twice in the manual for some reason. One table says the default is 7. The other says 12. The actual default is 5. The manual says that wire labels are provided, but none came with my unit. Finally, the manual says “Compressor protection is bypassed during testing” but does not explain what the “testing” is or when it occurs.There’s another version of the manual floating around the internet that you might find. Don’t use that one. Its table of system types is not even close to correct. The manuals have no markings to distinguish which version is which. Make sure to use the web address included in the package so you don’t end up reading the wrong manual.Finally, the thermostat was in an unsealed plain white box. There was no way to know if my unit had been sold before and returned.

Good looking z-wave thermostat
I wanted a zwave thermostat to run with home assistant so I could replace my nest thermostat. This is a nice looking thermostat that connects using zwave.This is a very flexible thermostat that can work with many different configurations. Make sure to read the docs and set the secret menu value to the correct value for your system. One interesting thing I found is that the thermostat will not function properly until it is configured in the secret menu and connected to your hub.I tried to set the thermostat up without connecting it to my hub and it would just start the air conditioning. Once I connected the thermostat to the hub it worked as desired.

I really like it. Great value.
I upgraded to a heat pump and was looking for one that connects through zigbee or ZWave since I own Hubitat hub already. Instructions in the manual are very detailed and may be overwhelming to some. But HVAC guy was able to configure it under 5 minutes even w/o working with this thermostat before.Operation: I had zero issues in five months I was using it. Menu is a bit cumbersome at first. But it is actually very simple – arrows cycle through the settings and a circle modify selected option. Scheduling is relatively simple but very tidious so it is best to use hub functionality to do it. I personally just set it to 73F for cooling and 66F for warming and run on auto.Other thoughts. I really like the appearance and the flawless integration with the Hubitat hub. The price is also very competitive.
