Amazing device / some routers may not play nicely

Edit update: ok did get the apps working, problem was in the router the internet company gave us. It blocked the port or protocol the thermostat needs to communicate to the phones. Once I hooked my Nighthawks ac1900, it worked flawlessly. I really hope this helps some one.Thermostat works extremely well. I get monthly emails with the previous months energy usage, really nice feature. Geo-fencing is working well for my wife, kids, and I. Only goes into away when all phones are out of the house. I must apologise for my first review, Changed my rating to 5 starts, due to the fact this device has exceeded my expectations once I got it connecting to the internet.Old review: The thermostat works great, nice touch screen. Easy to adjust temp, and modes, nice programmable time feature.The app used to control it though a smart phone on the other hand proved worthless to us. We really wanted this feature and felt that the price we paid for this unit deserves a working app. The problem is when we are setting it up through the app, at the very end it states it cannot find the device. Tried with my Galaxy s9 and my wife's Iphone x. We then tried various friends phones in hopes that maybe our phones were to new and not playing right with the app. I had called customer service and they walked me through the exact same set up that didn't work and got hung up on. Didn't try to call back. I will be looking into another brand for our next purchase

Seemed easy to set up.

Turns out this installation was easy, very simple. I have three systems (central air and gas furnace), and still had the original construction grade non-programmable thermostats from 12 years ago that used up batteries and wasted energy. The price is right, and Entergy has a rebate program. I installed two so far, and will definitely replace my third as well. Like others I had an unused blue wire running along with red, green, white, and yellow. The instructions in the box were simple and clear. Up in the attic the blue wire was cut several inches shorter than the rest, but it was easy to repair. My system had connectors R C W Y G for red common white yellow and green. All wires except blue were already connected, so I connected it to C. The wire that runs to the outside condenser unit was connected to C and Y. Installation of the new thermostat was straight forward. The new thermostat connected to my wifi router right away. I used an ipad tablet with the Honeywell Home app to set it up. I also bought an echo so I could check and adjust the temperature through Alexa. I set it n a schedule, you can have a different schedule every day of the week. I have not tried the geofence. I’m very satisfied, but this is day 1. It appears the most difficult thing is to figure out which interface is going to work the best, whether its Alexa, Honeywell Home, geofence, or something else.

Great smart thermostat

I have had one of these for several years, and just recently moved into a bigger home. I brought that one with me, and added 3 more because the new home has several zones for heating and cooling. They all work great together, and I was even able to install one of these on electric baseboard with the help of an Aube RC840T-240 relay. Even though the instructions for the T5 thermostat say you can't use it for 120/240VAC systems, that Aube device makes it possible. The price fluctuates quite a bit on this thermostat, so wait until it goes on sale and scoop it up. You won't be disappointed.

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.

Fantastic thermostat. Setup was a breeze.

Some people have had a hard time setting this thermostat up. I'll note a few things I noticed.Firstly, make sure you set your WiFi router supports 2.4 ghz with WPA+PSK+AES. Most routers these days support both 5 ghz and 2.4 ghz connections and multiple WPA and WEP security schemes and many will be setup by default to use WPA+PSK+TKIP. TKIP is not as secure as AES and many newer devices will not support it. That includes this thermostat. So switch your router to AES before beginning installation.Secondly, it's way easier to do your initial setup on an iPhone or iPad rather than an Android device as the Honeywell Home app will automatically read the Wifi configuration on your Apple device and send it to the thermostat. This won't happen on Android; you'll have to manually type in your WiFi password if using Android.Once you've set up the thermostat, you can control it with your smartphone. The next thing you'll want to do if you have an Echo device is setup the thermostat with Alexa. You have to add the Honeywell Home skill to Alexa and then link your Honeywell Home account to the Alexa App. Once you've done that, make sure you discover your new thermostat or Alexa will be unable to control it.Once it's enabled, you can say things like "Alexa, what temperature is my thermostat set to?" or "Alexa, lower my thermostat by 2 degrees.."The thermostat is instantly controllable from anywhere in the world (as long as you have your smartphone!).And, if wiring it up sounds scary to you, you can always hire an HVAC technician to do it for you. But, honestly, if I can figure it out, probably anyone can. :)
