Works as advertised. I can turn it on to warm up my place before I get there and I can check the temperature from anywhere.
I would recommend this to a friend!

Good - but not Great.

When one of my two thermostats died, I replaced both with T9s. The installers advised me not to bother with the added room sensors - but despite the confusing instructions, I included them and they have helped to level room temps. What bothers me most is that they both measure 3 degrees lower than the actual room temperature. I have tracking thermometers placed in each room and they always read 3 degrees higher. True - I can adjust accordingly - but if this is a quality instrument, I shouldn't have to.
No, I would not recommend this to a friend.

Primitive design.

Primitive design. No option for timed fan run. Overly sensitive causes unit to short cycle.

This thermostat has remote room thermostats that work great. Being able to set the temp in our bedroom at night has been great.

Worked great for a few weeks.

Worked great for a few weeks. It was awesome having control from anywhere. All of a sudden i was getting alerts every day saying the system was offline, then online, then offline again. I reset the wifi connection which didn't help. There have been no changes that could have affected it. Probably going to remove it and go back to a regular 'dumb' thermostat.

It doesn’t stay connected to my wifi. It will connect and then stay disconnected from there on out.
