T5 Plus Wi-Fi Touchscreen Smart Thermostat

This thermostat is a very good value. I had little to no problems with the install. I read alot of reviews and figured out everything I needed to do before the item arrived. I would say that HVAC systems can be wired in a number of ways and the generic instructions provided did not match what I was seeing in my HVAC. I did not have a control panel in the air controller where all the wires were connected to. I did notice four wires coming out of the air controller which were labeled W, C, R, and G. I saw 4 wires, W, G, R, and Y, connected to my old thermostat and the blue (c) wire not connected. I also saw that the blue wire on the other end at the HVAC was also not connected to anything. I saw three of the wires W, G, R connected to their corresponding labels coming out of the air controller via wire nuts. I saw the yellow wire connected to another wire going somewhere else, which I correctly deduced was the AC compressor. (I found online that the yellow wire is to tell the AC when to come on) Also going to the AC compressor was a black wire connected to the C wire coming out of the air controller. All of that is to just show the generic directions were no good to me. I am not an HVAC installer and did not know the purpose of the wires before this. I actually found a diagram online which showed me the installation I was dealing with. I decided that all that was needed for me to do was to strip both ends of the blue wire (C) and connect it to the air controller's c-wire, along with with the AC compressor's c wire.When my thermostat arrived, I connected the thermostat to the wires per the instructions. I did overlook pushing up the switch for the jumper RH RC so at first it did not work. After I pushed that switch up, I had power. After reading about putting the phone into airplane mode, I did this to start with and followed the prompts on the thermostat and phone. It connected quickly and seeminglessly. The geofencing has worked well so far. There is limited scheduling ability along with geofencing and it works for me. I have set a temperature for when I am asleep, when I am home, and when I am away. (this is pretty much all that is available when you are using geofencing) There is also a vacation setting which I will be using on my next vacation. I like that I can communicate with the thermostat outside of my home. For instance, when I am on vacation and the temperatures are very high or low, depending on the time of the year, I can turn on the air hours before I get home.It does have the auto change over setting whereby it will change from AC to Heat automatically. It works pretty good because there are two sepereate temperature settings for cool or heat. I have my heat set to 68 and cool set to 76. This prevents the ac from running in the winter and the heater from running in the summer. Of course, if you really want to waste electricty, you could set the two settings temperature close to each other and then the heat would turn on in the summer and the ac would turn on in the winter. (I thought the purpose of these things are to save electricity?)I dont have an ECHO ecosystem, I am a Google home person. I have successfully intergreted the thermostat into my google home. I am able to turn on the air or heat. The only complaint I have is that the thermostat has seperate cool and heat temperture settings but when I tell google to turn my heat, or air to a certain temperture, it turns both settings to the same temperature no matter what the verbage I use.I bought my thermostat through Amazon Warehouse so it is even more of a value buy. Many people do not realize that most of what Amazon warehouse sells is open box products. (brand new products that were sent back). It was not used at all. I always get the ones that says packaging is damaged but the product is new...
