Love this!
Love, love, love! Customer service is amazing, the rep walked me through a blown out fuse. Once we changed the fuse, the unit worked flawlessly. Easy to install and register. The unit is so sleek and beautiful. Highly recommend.

Great thermostat don’t miss it
Very easy install and set up. I like the app and multiple operating OS. I especially like the geo fencing perimeters, it ranges from close to 10 miles or more. Other thermostats that I have tried are only a few hundred feet.I also like the vacation set up also very nice programing. I am a heating & air company owner. I have been in the business over 30 years, and I give this thermostat 5 stars plus +++

Worked for 2 months
We have a 20+ year old HVAC system that we wanted a wifi enabled thermostat for, convenience and what not. It was pretty easy to install, especially since the C-wire adapter is included and the price especially was right. Worked immediately with our AC system and both thermostat and app were user friendly. Fast forward, two months later the thermostat wonât even power on. We re-installed the 20+ year old thermostat and the system works. We bought a new, more expensive Honeywell and that worked immediately as well. Not sure what the issue is with the Cielo thermostat but we can rule out our old system as the problem. Unfortunately the return window has passed and we are out the $80+ after only 2 months. You get what you pay for I guess.

Very nice thermostat. Great customer service.
I now have a total of eight of these thermostats. Five of them for Mitsubishi heat pumps, mini splits, 1 for a Tosot-gree heat pump, mini split and two for conventional hot air and hot water baseboard. For the heat pump, mini splits, it was pretty much plug-and-play after following the directions. The hot air system with AC in my house would not work after following the wiring diagram. I called customer service and spoke with Jason and after a few pictures back-and-forth figured out that I did not have a C wire to my thermostat. Made one connection at the furnace and we were up and running. I find these thermostats, more user-friendly than the thermostats that weâre going to come with the Mitsubishi and tosot heat pump mini split units. The six thermostats that I have for my heat pump mini splits are 400 miles away and I have no problem controlling them with the app on my phone.

Easy alternative to the big brands with an awesome support team
Recently added some mini split heat pumps in my house that did not have wifi controllers, which lead me to stumbling upon the Cielo brand to control them using their other product. Since I didn’t want to have multiple apps and preferred to keep everything together, I ditched my other smart thermostat and switched to this new one by Cielo.So far it has been great! My setup is very basic with a two wire oil system, so I’m not using any of the more complicated features, but it does the job. Setup worked perfect with an additional plug in adapter to add a C wire. No issues with wiring complaints like some of the other smart thermostats when you try to add a fake C wire.The only problems I’ve seen (across all of the Cielo products, including this one) is that they seem to be very new products, so there are a bunch of minor bugs here and there with the interface, scheduling, timing, etc, HOWEVER, their support team has been extremely responsive in assisting and have rolled out fixes very quickly. Still giving it five stars because of the support! If you have any issues don’t hesitate to reach out to their support team.Finally, I feel like the interface of the app could be streamlined better to be more intuitive, there is quite a lot you can do and it can get confusing quickly mixing multiple devices and models, but most of it is just UI/UX and will get better with time.No regrets, good products over all.

Great thermostat, easy to install
Great inexpensive thermostat. Very easy to install. I took pics of both my furnace wiring and thermostat wiring BEFORE I started to install. I do a lot of DIY stuff, but get intimidated sometimes by the project and I procrastinate. This one was easy once I started and was up and running within 30 minutes.
