Quick and Easy install, even for an old HVAC system...
By Mr. Hand on Reviewed in the United States on August 2, 2023
My house was built in the 60s, the HVAC is about 20 years old... I bought this to help maintain better temperature in the home and better regulate the older system... It works fantastic. It comes with the adapter to hook up an older system... it plugs in just right, super easy... And it maintains the temperature in our home much better... We get 2 total sensors in the package (the thermostat has a built-in one) and the extra one... and we bought 2 more of the Room Sensors (updated) and they link up to the system just fine. I recommend between 3 and 4 total sensors, on each floor, to give the system the best chance of working properly with this system. It is saving me money, nearly paying for the thermostat and sensors... by the end of summer, it will have paid for itself. That is a bonus, because next year, it will save me money. Alexa integration works flawlessly...

Ecobee4 Thermostat device goes offline and never working again
By NSK on Reviewed in the United States on October 13, 2020
I like this product,Ecobee4, when it is working. You can control the temperature from the phone and you can control when you're away and home. The problem is that when it goes offline, my A/C in Houston will be hot and can be unbearable. There are no backup or manual control to override offline. I called the Ecobee support and the lady was very helpful and patience. I give thumb up on service support but disappointed that the device didn't work. The support lady walked me through several steps to figure out the problem. We made several attempts but still didn't work. I took several pictures of Ecobee4 setup and everything was correct. Instead of trying to diagnose on my A/C main system, I told her if I can put back my old one and if that works then this product is defective. It's that simple.
