Review: Much improved - Update -- 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.
Review: Honeywell Lyric T5 Smart Thermostat - I ordered my Honeywell RCHT8610WF2006 Lyric T5 Wi-Fi Smart 7 Day Programmable Touchscreen Thermostat, via desertcart Prime ($107.99 + tax + FREE shipping) on 8/15. I promptly received it 2 days later, as promised. Frankly, you can't ask for anything better than that! After turning off the circuit breaker to my air handling unit, I removed the old thermostat and its mounting plate and photographed my original thermostat's wiring scheme, As my home had more than sufficient wires available for use, installation of the Lyric T5 was a breeze following the included instructions. Once installed, and upon resetting the circuit breaker, the T5 immediately powered on and displayed "Honeywell", followed by "Start Setup". Setting up the device was a simple process, thanks again to the provided concise instructions. After choosing the option of using the (previously installed) Lyric cell phone app to complete the setup, all steps were clear and easy to follow. Note that it's important to know what type of heating your residence uses. After a quick call to my "A/C guy" and with answers in hand (heat pump & air-to-air), I was able to complete the T5 setup in a matter of minutes. Connection of the thermostat to my home network was established without issue...it was practically automatic. With the T5 setup completed, customizing the cooling/heating controls to our liking was simple. While in the end we elected not to activate the Geofence mode, I may decide to do that in the future. If so, I'll update this review at that time. In closing, I find the Honeywell Lyric T5 Smart Thermostat to be an extremely capable and cost-effective product. It's an attractive device that is simple to install and easy to setup. If my initial experience is any indication regarding the quality of this WiFi thermostat, whether it will perform as advertised only time will tell. For now, I am extremely happy with this purchase.

## Questions & Answers

**Q: Can this be installed without a c wire. i only have 3 wires: rh, rc and w.**
A: Ah, the C-wire causes so much confusion. A thermostat is basically a switch (or 2 switches if you have AC). Each switch has a "hot" side connection to the power source and a neutral side connection that is connected to the furnace or AC unit. Rh/R and Rc are the hot sides for heat and cooling respectively and W is the neutral side for the heat source, Y & G are the neutral sides for the compressor and air handler fan.

The power source(s) are 24V transformer(s), where two transformers are usually used if you have AC but forced hot water heat (hence the Rh and Rc) but only one is used if you have an integrated HVAC system (AC + Hot Air) (Rh and Rc are jumpered together).

Dumb thermostats don't need much power and can run off batteries. Smart stats need continuous 24V power to run the WiFi, which is picked up from one of the R connections. And the C connector? It is the neutral connection back to one of the transformers from the WiFi.  It's needed because you don't get a 24V difference between, say, the Rh and W when there's a call for heat.

If you have a boiler only system then you can connect an external transformer between the (unused) Rc and C terminals to power these smart thermostats. Adding this external transformer to Rc is exactly the same to the thermostat as having a separate AC system transformer with a c-wire connection. Note: you should remove the jumper between Rh and Rc as you would if you had a separate Rc and Rh wire.

And if the other answers here are correct, you can also do this even if you have AC, but I don't know if you might mess up the chips in the thermostat.

Oh, yeah, the c-wire adapter that comes with the "T5+" version (or bought separately) makes use of the T5's "K" connector. The T5 has internal electronics the allow one wire (now called the K wire) to serve as both the G and Y wires and uses the second wire as the C-wire. The adapter is located at the furnace or AC unit and contains the inverse electronics that takes the K-wire and the C-wire from the thermostat and recreates the G, Y, and C wires to connect to the furnace.

Finally, if you don't have a furnace you can't use this c-wire adapter (you only have R and W wires) but there are 3rd party c-wire adapters that make the two wires act like three. [unfortunately they require you to install a small component in the wall behind the thermostat as well as the adapter at the boiler.]

**Q: I have power blinks often. If there is no battery backup with the Lyric T5 does that require me to reenter the schedule each time power goes off ?**
A: This thermostat utilizes a capacitor to maintain your settings if you experience a power interruption.

**Q: Can you turn the fan on without heat or cooling? Does this work remotely?**
A: Hi Susan, Yes you can use the fan without having to make a heating or cooling call to the system. Additionally, the Lyric app allows you to adjust the fan setting remotely.

**Q: App not emailing me**
A: Yes, I had the same issue during installation on July 12. I had to call the Honeywell support line and wait more than an hour on the phone to get my account verified manually. They claimed ignorance of any problem with email verification at the time, but clearly as of July 16 the problem was still there and their tech support had done nothing to fix it. Not a very good performance!

### ⭐⭐⭐⭐⭐ Easy installation
*by B***Y on February 5, 2022*

I was a little hesitant about buying this product after reading some of the negative reviews about wi-fi connectivity, but am very glad I did. The installation instructions are detailed and very clear. I had no problem with connecting to our wi-fi network and the Honeywell app worked very well on my iPhone. It did take a bit of time to complete some of the steps, but I think that has to do with a small microprocessor. There's a nice feature in the menu on the app that lets you add other users very quickly, so my wife has her own account and can control the thermostat with her phone. I didn't set up geo-fencing because it seems a bit impractical unless you live alone or commute together, though I imagine you can override it if you're the one at home. It comes with screws and drywall mounts and if I did it again I'd have drilled a pilot hole to see what was behind the sheetrock. Turned out the contractor put a board between the studs and I didn't really need the drywall mounts. It's really nice to be able to control the thermostat with a phone. Pre-pandemic at our old house we had one that had phone control and were on a February trip to the Yucatan peninsula. Warm and sunny and snowing in Portland. Bumped the temperature up on a layover and the house was toasty when we walked in the door. So far I've only used this one when I wake up before "Awake" on the schedule, but it's nice to turn up the temperature from under the covers. Plus, it's got a nice, clean minimalist look to it.
