Back when I left the house last spring with the Jeep, I left the A/C on... Forgetting completely that it should be returned to 90 degrees.. Of course it dawned on me as I was driving, but by that time I was most of the way to Holbrook... I vowed that I would have an internet controlled Thermostat before I left Mesa, again....!
I had to call the home security people and have them go over and reset the stat.. But I had no way of verifying that it was done, or what they had set it to... Nope not going to do that again...
I thought about purchasing a NEST learning thermostat, but it costs $249.... Beyond the cost, I wondered if I wanted to have the stat learning about visits from the security company while I was not here.... It would keep track of the motion of their presence, and try to keep them comfortable.... Nope that's not going to work....
So Honeywell makes a normal programmable thermostat that is controlled over the internet.. Has 4 Temperature times for every day... And auto switches from heat to cool with another different 28 period group of settings for the cool side as well.... Besides, it was only $150, at Home Depot..
This whole thing surrounds whether you have a common wire in your cable from the furnace... Since this house is only two years old, I assumed I would..... When I was trying to remove the old stat from its base, the whole thing came off of the wall... It was barely mounded in plastic dry wall anchors... But here is what I had.....
The G wire was green and W was white and Y was yellow and R was red... But the C for common was that blue wire in the center.... And sure enough the meter measured low voltage between that and the red one...
I took this picture to remember how it was before I removed the old base... Can't be too careful.. And I did turn off the furnace breaker as well... It wasn't too long and the new base was wired and fastened into the stud in the wall... No plastic hollow drywall anchors used....
With the wires matching their colors it wasn't long before the whole deal was wired and mounted... When I flipped the breaker, the stat lit up.... Collective sigh of relief... and the fan switch started the fan....
Here's the new one after the date and time were set, and its connected to the wifi... Note the antenna and signal bars in the top right..
You take your computer and search for wifi connections with OS like you were finding a different router... One will have the name thermostat and some numbers... You connect to that, and start your browser on the 192.168.1.1 local ip address... The stat answers you and offers links to all the routers in its view... You select yours and enter the password... It signed on and transferred my computer over to that router automatically... It offered the web site to sign up for an account, verifying the email you enter with a confirmation entry...
And just like that, I was on the internet with the new stat... I did download the app from the app store on my phone, and entered my newly set up passwords.. And........ I can turn up the heat from my phone.... Wowsers... Of course I could be in Kansas and turn off the A/C just as easily...
So if your old thermostat has a common wire and you have an internet wifi connection, here's something else you can use that expensive cell phone for while driving in traffic.......
It was a really nice day, so I went after that new stat and some groceries on the motorcycle... It saves mileage on the Jeep, but I'm fairly certain it will be more expensive putting miles on the three wheeler in the end....
