Installing the Cielo Smart Thermostat was a breeze, even for someone like me who isn't super tech-savvy. The detailed instructions and included C-Wire adapter made DIY installation surprisingly simple. I love being able to adjust my home's temperature from bed using the app - no more chilly walks to the thermostat in winter!

The energy consumption insights have been eye-opening. I never realized how much I was overspending on heating until I saw the data. Now, with customized schedules for when I'm home, away, or sleeping, I'm already noticing savings on my utility bills.

Customer support deserves special mention. When I had a minor wiring question, Jason from their team walked me through it patiently with pictures and even followed up later to make sure everything was working perfectly. That kind of service is rare these days.

While the app has tons of features (maybe almost too many), it's become second nature after a week of use. My favorite feature? Vacation mode - knowing my pipes won't freeze while I'm away gives me real peace of mind.

The only hiccup was some initial confusion with the app interface, but their detailed manual cleared that up quickly. After using this for three months across two different HVAC systems in my home, I'm convinced it's one of the smartest home upgrades I've made.
