I've used this 3 years. It worked fine until recently. It wouldn't connect to my wi-fi anymore. (No wifi changes) Showed "change battery" & "reconnect" errors. I changed batteries, & errors remained. I uninstall/ reinstalled the program 3 times!! After the 3rd time, I progressed through the connect to wi-fi pages far enough to see that there is NO SECURITY for my thermostat when using wifi. The app works now, but I'm wondering if it's worth it w/o added security.

The device itself and the app are great. But, although the physical installation instructions were concise and easy to follow, the wifi setup with an Android at least, was a nightmare. I tried contacting tech support to no avail. Finally, I was able to resolve the install on my own (I do IT, but it still was difficult). It required several settings changes on my phone, which should have been clarified before step #1. Do the people who write these terrible guides ever actually try to use them??

I just installed the Smart Touch ST75S. I found it very easy to mount, connect the wires, and power on! I thought it was a little strange that it only connects to 2.4GHz. Everything in my home is connected to 5GHz. It's a good thing that my router has both 2.4 and 5GHz. I gave it 4 stars for this reason! The overall setup is straightforward, and you must know what type of system you have. I have a one stage heat pump that required me to go into the "Advanced Set up" make the proper settings!
