    Not Surprised!!

    • Written by Harold G from LONDON

    Honeywell does very little testing before releasing products to the market. This results in customers finding all sorts of firmware/hardware bugs.

    "No Response" with HomeKit

    • Written by Steve C from Peoria

    Piece of junk. Most of the time I get a "No Response" message with HomeKit or Siri telling me "Your T5 thermostat is not responding." After months of problems and no help from Honeywell, i dumped it and replaced it with an Ecobee, which has been solid so far.

    Hot Cold Set Points

    • Written by Ravi R from Santa Clara

    I got this because of its compatibility with HomeKit. While the thermostat itself supports setting different hot and cold set points - HomeKit does not (offers only a single set point) which makes the HomeKit support completely useless. For example, changing the single set point to 70 when the temperature was 68 first results in the heater heating the house to a little beyond 70, then the cooling kicking in to bring the temperature back down a little below 70, and so on... Just to be clear, the thermostat itself works fine, it’s the broken HomeKit support that’s a deal breaker here.

    The connection to HomeKit is unreliable. I usually have to open the Honeywell app to adjust the temperature. Sometimes Siri says that the device is not responding. I also hate that it requires a connection to Honeywell’s unreliable servers. I will be selling this junk and replacing it with iDevices thermostat.

    Best Thermostat!

    • Written by Chandelor A from Topeka

    This thermostat is the best HomeKit compatible thermostat for the price. It took me a little while to setup because we had to run a jumper wire due to the age of our old thermostat. Honeywell customer support was so helpful throughout the process. If you put it together and you’re not getting power to it or HomeKit isn’t work it could be due to the “C Wire.” Once I figured this out it operated perfectly. We’ve had it for over a year now and it has functioned flawlessly. The HomePod interacts with it perfectly! I also love the monthly energy reports emailed to me from Honeywell. I highly recommend this thermostat. You won’t be disappointed! Utilize Honeywell customer support if you run into any challenges during the setup.

    Connecting I phone 8 to Lyric T6 wireless thermostat

    • Written by Moira R from Sutton codfield

    I had this thermostat fitted four weeks ago, at first I found out through Honeywell that their server was down that was after numerous telephone calls. I now have talk talk broadband and I am still unable to connect my phone,the thermostat is configured and set up but I get to the very end of trying to pair my phone enter the four digit code and then it tells me “error” unable to connect” I am finding this so very frustrating it has cost us £300 plus all the time wasted for the engineer and ourselves to have a thermostat that is useless, I have a call booked again with Honeywell for Monday, they say it could be “talk talk” can anyone tell me if they have had any issues with talk talk and the connecting of their phones to the thermostat, I would appreciate if anyone has had the same problem for any comments that may help me with this issue.

    USed to work with Homekit until Lyric app was updated

    • Written by Diane L from Lake Worth

    I purchased this app a few months ago and it worked with the Homekit. Then Honeywell Lyric updated the app and now it doesn't work with Homekit. Not sure if it is Homekit or Lyric fault. Can't seem to find any information on this.

    Great product !!!

    • Written by Barry I from Walnut Creek

    This device was easy to install, program and manage from day one...
    It does everything I need in a single zone thermostat. Compatible with all digital assistants including Apple.
    Favorite features include: Geofencing which works amazingly well; Remote control from the app when away; automatic vacation advanced planning.
    And the price is right !!!

    run from this product

    • Written by ABE D from TULSA

    I bought this 150.00 product as a gift and wish i would have went with the Nest. Installation as far as wiring was a piece of cake but programming it through the app is a different story... Every time i have tried to connect the device to the app and to WIFI, i get a "Device not found error".. I have called tech support several times and the issue still has not been resolved, So i am going to box the piece of sh@# up and send it back... THE MORAL OF THIS STORY IS.....DONT BUY THIS PRODUCT!!

    Works wonderfully with native App not with homekit

    • Written by Lou K from Cary

    Nothing but issues with this thermostat and it’s conn to HomeKit.
    Half the time I try to use Siri with this product it becomes non responsive. I’ve tried troubleshooting to no avail even swapped for a new thermostat still does not work properly.

    Trouble shooting steps included multiple factory resets, Assigning the Lyric a static IP, assigning it it’s own 2.4 ghz network on its own LAN, putting it on a mesh network. So far nothing has solved my problem and Honeywell points the finger at Apple. It’s been almost a year of this nonsense and it’s still not fixed.

    So close and yet so far...

    • Written by Rick S from Yellowknife

    Installing the T5 was easy but the instructions that come with it are horrible.
    They attempted to write the instructions so that anyone could install it.
    They succeeded in making the instructions a bunch of gibberish.
    Luckily this is the age of google and a quick search solved that problem.

    Installing the app is also easy. Set it up on 2 iphones and programmed the geofencing.
    Worked like a charm, kept temps as programmed and sent notifications when I crossed the boundary.
    On the 4th day it stopped sending notifications and no longer recognized 2nd phone.
    5th day, it didn't recognize either phone.

    I finally got an email from Lyric with 2 steps to try.
    Did the 2 steps and sent them an email saying it didn't work.
    This is the response I got.
    "I am truly sorry that you are having issues with your Lyric T5.
    Please keep in mind that if you wish to proceed with the troubleshoots we are more than happy to help."

    I bought the T5 because of the geofencing but now I have to use the daily program mode.
    Better than a regular t'stat, but not what was promised.

    If the unit had kept working as it did for the first 3 days I would be writing a completely different review.
    I think the T5 itself is not the problem. The app however, seems fairly glitchy.
    The support is abysmal, emails are not the way to trouble shoot something like this.

    Honeywell Lyric App (downloaded from the App Store)

    • Written by Peter A from Bangor

    The Lyric app does not communicate with the thermostat. This renders the system almost useless for the purpose it was bought. The thermostat is expensive at £150.
    It is disgraceful that Apple should hold this app in their store.

    Product only as good as its weakest lin

    • Written by John P from Terrebonne

    Lots of weak links throughout the software and hardware. Tech-support of any kind is nonexistent. Luckily the AC installer at my house. He called Honeywell. After 15 minutes of back-and-forth, got the app to work. With software loaded on both my iPhone and my iPad the outside temperatures iPhone verifies correct reading; 72°F; conflicts with the iPad reading 91°F. The sleep option cycle does not integrate with manual operations correctly. Could not fix these design failures . Geo fence seems to operate as though the two devices don't recognize each other… If one is away both are away. The home/away settings on the thermostat appear to override the geo-fence. Fortunately you can override everything by manually changing the temperature on your iPhone. This is not a set it and forget it system. Also the lack of confirmation of existing sittings leaves doubt as to the system status. Honeywell… Burn me once shame on you… Never again… No shame on me for sure. This device came with my air conditioner. I should've done my own research. You have some good ideas… Your execution is abysmal.

    Works nearly perfectly

    • Written by Jim M from Poway

    I really don't understand the problems or issues of the other reviews... I've had my T-6 (same as T-5 just different color) for 5 months now. I LOVE IT.

    My thermostat installed in like 15 minutes start to finish. My son installed it, not a pro.

    Setup was easy. App works great, love showing it off to people!

    I typically use geofencing to reduce power usage while I'm away from the house, it works VERY well.
    While home, it maintains a very even temperature.

    It has lost connection to wifi 1 time (my wifi is finicky and is reset at least weekly). That's better than the rest of my smart home.
    I simply pulled the thermostat, waited a few seconds, and in 5 seconds it was up and running.

    I'd say this deserves 5 stars for a great thermostat, great app, and arriving home to a comfortable setting!

    Future Look:
    My only wish would be a sensor so that when people leave doors and windows open that it wouldn't even try to heat/cool the house! After a minute or so of being left open, it should send a msg to me and shut off. Honeywell, here's a great idea!!!

    OK thermostat terrible app

    • Written by William W from Winter Springs

    Purchased the Lyric T5, mounted it on the wall, connected the wires as per instructions. Install is straight forward, however setting up the app to finish installation is anything but simple. After an estimated 15 attempts I did finish the set up and for the past month have been using my iPhone 6s to control the thermostat. Twice during the last 30 days the app would lose connection with the thermostat and I had to go through the whole set up process again to reconnect. Yesterday after going through the entire set up process with no luck I called tech support and after a 45 minute call did get the thermostat working again but still no wifi connection with the app. I live in Florida and after 45 minutes of no AC we gave up trying to get the app to work. Yes the process does shut off the AC. Today called tech support again, deleted the app, reloaded the app, went through another 50 minutes of tech support and still could not get the app to finish the set up. The tech said there was a problem on their end and he opened a tech support request to try and resolve the issue. Life is too short to continue to deal with this. FYI if you go to the app and click on the 3 lines on the top left to show the settings screen and push and hold the word "home" it brings up a debug screen you can email to tech support so they can see the issues. I'm returning the Lyric to Home Depot. Don't have the patience to deal with it.

    Love this thermostat. Great product Honeywell.

    • Written by Jason B from New Albany

    I installed it in February. I am only 26 & I was able to hook it up & get it firmware updated. The geothermal feature is nice. It is IFTTT compatible too. For example everyday at 5pm change temp to 72 degrees. I can't tell you how many times I've been upstairs in my bed & said "Hey Siri change temperature to 72 degrees." Instead of walking down stairs to change temperature like I use to. I have a Quiet Comfort Honeywell Tower fan upstairs too. Love love love this thermostat.

    The T5 was relatively easy to set up, but there were some network issues with it communicating to the servers @ Honeywell and it would always be offline. Several calls to their technical support and basically they said I needed to contact my internet provider. I've had a Nest and most recently the ecobee3 and never had an issue with either connecting to their respective servers.

    My solution, return both T5's and buy 2 new ecobee3's. Those are both up and running in my house and no server issues at all.

    Honeywell's last of customer support have incredibly surprising and now they've lost a customer.

    Professional install, easy app setup, couldn't be happier

    • Written by Robert M from Ballston Spa

    We had two of these installed along with new AC systems for our house. The techs hadn't installed a lyric before but had no trouble with them. They did need to run a common wire, but this wasn't a set back. There's no way I could have installed these myself without pulling my hair out. However, for the guys that work with these all day...it was a breeze.

    They were amazed at how quickly I got everything going with the Lyric app on my phone. Once they left I quickly had it setup with HomeKit and was able to share the controls with my wife. I think these look great compared to the standard white/beige units I'm used to seeing in homes.

    The verdict is still out on long term performance, but I'll circle back once I've had a few months to test these out.
