A nice upgrade
Top reviews from the United States

- Reviewed in the United States on July 25, 2018I should have come on here much sooner than now for an update. But I can honestly say this is now a 5 star. I've saved so much money since switching and I haven't had any issues. Performance wise this works great👍.
I just installed this today, so this isn't so much based on performance as much as the installation process. I had read the reviews prior to buying this and I could tell I might be in for a hard time. I can tell you that for the few hours it's been running, it works excellent and I like everything about it. But you shouldn't trust a review based on so little time.
So let's say, assuming there are no future problems, for the $$, I thinks it's remarkable. Also, the app set up is so smooth and easy you'll have everything you need ready in minutes.
The biggest concern you'll have with set up is whether or not you have the "C" wire. If you do not, there is a relatively simple solution. You'll have to get into your furnace though so it's going to take a bit more of your time. And your patience. Can't stress that enough. Honeywell provides you with an extra wire so I assume there are many people who will run into this problem if you have an older house/condo. The thermostat itself doesn't require the extra wire, but your furnace will. I'm not the most handiest of men, but I figured it out pretty quickly. I could take a few minutes explaining what goes where and how,
but the best thing to do is to go onto YouTube and type in "smart thermostat no C wire". There are a few people who will walk you through it, but even Honeywell themselves have a video for this (that's what I used). The narrator talks a bit slow (remember, patience) but I found it to be real
simple as she explained it.
The other problem I had was with the WiFi connection. I kept getting an error that it wasn't connecting. I don't have a sure-fire solution to this but I had to reset the thermostat two times and on the third try, it made the connection. This lasted about a 1/2 hour trying to figure out why it wasn't connecting. Still don't know exactly why it was so difficult, but in the end with persistence (and luck?) it's now working.
If I do have problems with the performance I will come back here to let people know. Because for everything it does (geofencing!), and the ease of use of the app, it seems like a no-brainer to get it for the price. And if the performance is good for a while, I'm going to change the rating to 5 stars.
- Reviewed in the United States on March 24, 2018Update -- I changed my rating from 3 to 5 stars. With the latest updates it's working really well. I'd still like to have more flexibility setting schedules and hope that'll be included in a future update.
The positives:
- Very easy to install. All three connected to my router with none of the issues described in many other reviews.
- No problem using them with both Siri/Apple Home and Alexa/Echo.
- Intuitive user interface
- The iPhone app is generally reliable and intuitive (but not entirely...)
Negatives:
- There is only one set of four time periods per day that cover both heating and cooling. Because of variable electricity rates where the rate change happens at different times by season, we use different times for heating and cooling settings. This thermostat does not support that. I'm hoping for a software upgrade that allows the addition of more time periods.
- There are occasional dropouts of connectivity with WiFi. So far they've re-connected on their own reasonably quickly.
- The server the iPhone app connects to is occasionally unavailable and the app fails. This happens more frequently than seems reasonable.
- The iPhone app does not refresh very quickly and there seems to be no way to manually refresh (by pulling down and releasing for instance). It's hard to tell it hasn't refreshed because it seems to behave normally. The only way I've found to force it to refresh is to kill and restart the app.
- Occasionally I make a change on the app and it seems to accept it, but then it reverses to the original setting. There is no indication that a commanded change has or has not been accepted by the device.
- Reviewed in the United States on January 25, 2018I was hesitant to buy the product because of many negative reviews that it didn't work, couldn't get it setup, etc.
However, on couple sites, I saw it as one of the best smart thermostats at a decent price and decided to give it a try.
Yes, it does require a C wire - if you are not sure what it means, it would help to check with your HVAC guy. Installation guide has also a method without using a C Wire (using Green wire for C Wire purposes), but then you loose the ability to control fan without Furnace/AC, if you want to run the fan only for example...Your furnace board needs to be able to support the C Wire connection regardless. The problem with the newer, more feature rich thermostats is that they need more power than just when the furnace/AC is on + couple AA batteries to keep the wifi connection and bigger/nicer displays, etc. C Wire provides that additional power from the furnace...
I had a 4 wire (18-4) running from thermostat to furnace. Since I plan to stay in this house for the long haul and wanted to do it right, I bought the 18-5 thermostat cable (18 gauge each - 5 wires) and ran the new cable from thermostat to the furnace and removed the old cable. Connected to the furnace and to the thermostat all in less than 45 minutes. Turned on the power, followed the instructions to install the honeywell lyric app, connect wifi, setup the daily schedule from the app and furnace turned on within couple of minutes like nothing ever happened. Very happy with the setup and thermostat so far...
Update 7 months later - still very happy with the product, buying a 2nd one for my 2nd furnace/ac...

5.0 out of 5 stars Funciona con HomeKit, fácil instalación
Excelente producto, funciona muy bien e increíble relación calidad-precio, tiene muchas funcionalidades como uso con Siri, que otros productos (incluso de la misma marca) no tienen. La instalación es super fácil, si ya tienes cableado con otro termostato hay que asegurarse que tenga el cable C.
Yo instale el termostato desde la calefacción y solo necesite comprar cable eléctrico que tenía 6 cables de colores dentro. Muy muy fácil de instalar.
La programación también es muy fácil. Si eres de México hay que poner en país a EUA para que te permita configurarlo pero al terminar la configuración, cambiar el país a México y ya te permite poner tu dirección para que veas la temperatura exterior.
Excelente compra.

1.0 out of 5 stars Not secure, unreliable!
This product is rubbish. The wifi constantly disconnects making the device disappear from the app and from homekit. The worst problem is that the device will not accept wifi keys with special characters in it. Difficult to set up, unreliable networking. Keep clear of this guys!

5.0 out of 5 stars Best thermostat
People complain about the setup but are usually technologically illiterate. Setup was fast and easy. Longevity wise it hadn’t disconnect from the wifi by itself at all. The mobile app itself is a little buggy. If you were to change the temperature In app sometimes it changes back to what the schedule was set at by itself. Other than that, it works flawlessly with both wifi and Apple HomeKit.

4.0 out of 5 stars Installation was easy but setup can be difficult for heat pump system.
Installation was very easy. We have a heat pump and the old thermostat had a w/o/b terminal but the new T5 Lyric has separate W and O/B terminals so I had to do some research online before figuring out that I need to plug into the O/B. The installation instruction was not descriptive in the installation of heat pumps. The setup was also a bit dicy and requires you knowing how the reversing valve actuates to cool or heat. Overall the setup had to be the most difficult part of the entire installation. Seems to work OK now but there were some dodgy moments when changing between cooling and auto changeover modes.
