Honeywell Home Lyric Round Wi-Fi Thermostat - Second Generation (RCH9310WF)

It's very cool. It works well. Awesome but... it has some trouble with HomeKit. Not totally ready for prime time. The last update seemed to fix some of the connections to my phone. I run the home from my iPad. Very important that you set up a hub. The iHome smart plugs were SO easy to instal but for this I had the HVAC dude out. I didn't want to screw it up. Prolly something a handy dude could do himself. Whatevs. So I'm not that dude. Now the Lyric is set up, and most of the time it talks to my phone and my iPad. Even when I'm gone. But you prolly will get messages in your Apple ecosystem that the Lyric is "updating." It usually plays nice, but sometimes its gonna happen. If you can't deal then don't get this thermo cuz its not perfect. I totally thinks it is SO awesome I just wait for it to come back. It's not like I change the temp 5 times a day. I set it and leave it. Switches on the AC as needed. Will even switch between heat and AC auto. It lights up when you walk by. I kinda like that--pretty cool.UPDATED 5/13/2017:Ok, so Lyric has done some major firmware updates, and Apple updated to iOS 10.3. The thermostat is now totally awesome. Never goes off line any more. It is always synced to my Apple Home--iPad, iPhone whatever. And now 5 stars earned. My best bud saw it and went home to order one for his house. It's that cool... and hot when needed.

They start off by telling you on the box that if you don't have this thermostat installed professionally, you void the five year warranty. That means you, homeowner!The app then lead to very carefully through the installation of the new thermostat, and it does a great job with the electrical and mechanical bits. Thermostat wiring can vary quite a bit, so they have you take a picture, and tell the app what wires you see. These appear later in a diagram when you're doing hook up.Wall mounting is easy and the device even comes with a built-in level so you can get that right.The software installation is not nearly so clear. At one point, you would expect it to list the Wi-Fi services that it can see, but it couldn't find the three services I had blasting in the room. I ended up entering the necessary wifi info for one of them. Apparently it took, but the app did not seem to realize this. This left me continuing to try to reconfigure it, getting an error message that said it was already configured.I never got a "congratulations your thermostat is hooked up to the Internet! "Message from either the app or the thermostat. But clearly that's what happened.The app needs to switch back-and-forth between your Wi-Fi network, and the thermostats Wi-Fi network. But the switches are not made clear, and the activity meter gives no indication what it is waiting for, so you can sit there for minutes waiting for something to happen. They really need to work on this part.I followed the directions for hooking this up to my SmartThings hub, and that seems to integrate just fine. There are still a lot of features involved in all this that I haven't figured out, but the basic seem to be working just fine.Aside from the set up confusions, this seems like a fine product. I'm looking forward to using it.-- revised review:I bought two of these, with great hopes. Honeywell has been in the thermostat business for a long time, and these were to replace two of their old model.The first one stopped working: it would boot, and just sit there through its partially-display sunburst initialization. I could find no documentation for its status. I contacted Honeywell, and we went through some quite technical debugging, involving special wiring and my voltmeter. They were well-prepared to do this, and eventually sent me a new thermostat, which worked fine.Then my second thermostat stopped working, its booting halting somewhere else during initialization. And the first one? It now appears to work, but doesn't turn on the furnace.So these devices have two problems:- they seem to de after a few months, and- their diagnostics are totally useless. This is a shame, since they are little computers with displays, and could in principle supply exact error condition indications, with web-accessible documentation for dealing with them.So, I have reverted to the old thermostats, and am looking for some other new ones.

The thermostat was pretty easy to install on a House built on 2005 only thing is the C wire wasn't hooked up on the furnace end but thats not a big deal because the extra wire is there it just needs to be plugged in on the board. If you don't have a C wire on your thermostat already but have a spare blue or black wire all you need to do is connect that to the C screw on the control board in your furnace. Overall other than that the thermostat works well and is easy to operate.Pros:Easy to install (30 mins or less with existing wiring)Easy to use appMoney Saving features with away modesCan auto switch between heat or ACCan auto set away temps based on outside tempHourly weather screen to check the weather quickly"C" wire (For Constant Power) is only required for Apple HomeKit use (Recommended though or it will go through AAA batteries pretty fast)Cons:Plastic is a little brittle on the wire connections ( Don't press to hard when releasing a wire or it may snap off)Some models sold on Amazon are Contractor models and the 5 Year warranty is voided if installed by a homeownerContractor mode in settings to test that the thermostat is controlling heat and AC and check battery % is password protected (password is the 4 digit date code in device info)

I own 3 of these and intend to purchase one more for our 4 zone house. Initially I had a rough start with these as I do not have a common wire and relied solely on the battery. It does okay without the common but it really dumbs down the capability of the thermostat. I bought the Fast Stat common makers from Amazon which is a product that adds a common to your 2 wire lines without needing to run ANY additional wiring. The common makers did WONDERS for my Lyrics! I have not experienced a single issue since adding the common. My boiler and zone controllers work perfect with the Lyrics!

Looks nice but have to reset it every week. Keeps coming off the wifi.
