Connects to the WiFi network.
The thermostat works well and we love the ability to adjust the thermostat from our phone app because the thermostat is connected to our wifi. The thermostat is easy to program and has enough flexibility for our family.

Cheap and simple, but mighty for a refurb!
I basically wanted wifi for the cheap basic stupid thermostat I had, for not a lot of money. Enter this review…I got it mounted and setup in about 30mins while making sure I was following the directions. It was pretty much plug n play for my HVAC system. It was pretty easy to get the wi-fi setup and working through the manufacturers app. I had no problem getting it setup in Home Assistant through the Honeywell Total Connect integration. Now, I can set my thermostat anywhere, and use just about any entity for automations in Home Assistant. I have total control!The unit is refurbished, but came in excellent condition with no noticable wear/imperfections, appeared to have came with all needed parts, manuals, and works as advertised. You DO NEED a C WIRE to power the unit! I got it for a little over $40 which is a ste… I mean good deal! :-DNov. 2025 update, I haven’t had hardly any issues with this refurb unit, nor have I really touched it, but to see if the buttons still work. I supplied a recent image to show at bit of what you can do with Home Assistant. I managed to diagnose my AC before going out over the summer when the cooling cycles were progressively getting longer.

EIC Bypass Required, But Worth It for This Affordable Smart Thermostat
⭐⭐⭐⭐⭐ “It Works Great—Once You Wrestle It Into Submission”Nothing about wiring this thermostat was simple… unless you consider rewiring your entire HVAC system “simple.” That said, I’m still giving it five stars for the price, the design, and especially the Wi-Fi interface, which is slick once everything’s up and running.⚠️ Heads-up for anyone with an EIC (Equipment Interface Control) from a previous thermostat:If you try to connect this thermostat using the 3 wires coming out of the EIC (that was previously installed) like I initially did, prepare for frustration. There won’t be enough power to run the new thermostat—it’ll just sit there, mocking you with a blank screen.💡 The fix?Bypass the EIC (from the previous install) completely. I went with a good old-fashioned wire-to-wire hookup, cutting the EIC out of the loop entirely. Suddenly, the thermostat powered on like it had been ready all along. Magic.📲 As for setup:Get the Wi-Fi connected first. Download the app, create your account, and don’t forget to click the email confirmation link—it’s easy to overlook. After that, you can log into the app and set up your heating/cooling schedule with times and temperatures.✅ Final thoughts:Once installed, this thermostat has worked flawlessly. I’m very happy with the product overall. Big shoutout to customer service, who quickly helped me locate the MAC ID and MAC CRC numbers (pro tip: they’re on the back of the thermostat itself, where it connects to the base). and is required for completing the account set up and syncing your thermostat with the Wi-Fi network. Once that was cleared up, everything synced smoothly. Highly recommend—but bring your wiring patience!

Does not work- heater still running 8 degrees above the set temperature!!
Butter beware- see photo!! We keep it pretty cool in the house overnight, due to a genetic disorder that causes my son and I both to overheat easily, and become ill. In the photo, you’ll see that the thermostat is set to 61– I just woke up sweating and nauseous, and the heater was running. It’s 69 degrees in here- eight degrees above the set temperature, and I had to turn the system off to get it to stop running!! It just got cold enough to be running the heater where we’re live, but it was also having issues with the AC– it would run for less than 5 minutes then turn off for less than 5 minutes, over and over and over. I even timed it because I noticed how often it was clicking on and off. I’m going back to a Nest thermostat, because this thing is garbage.
