RTH6580WF Wi-Fi 7-Day Programmable Thermostat, White

Bottom Line: The installation was ALMOST effortless, and the performance has been rock solid. I'm very pleased by the unit and would certainly buy it again. I, too, had to unplug the unit once during installation in order for it to complete the temporary wifi connection to my android phone. However, that was the only hiccup. Otherwise, the installation went smoothly. In short order, the wifi link to my WPA2-encrypted router was complete, using a 2.4 GHz channel per instructions. For the past month, I've monitored the home remotely to determine if I needed to engage the aux heat strips during unusually cold periods. I currently live 500 miles farther south, and have not yet moved into the home, so remote control of the HVAC was the purpose for the purchase. The thermostat interface is simple and basic, but entirely sufficient. I don't have to mess with it to see the relevant information; it's all there on the main display. As a recently retired electronics engineer, I have an extreme distrust of new technology, because most companies chase the easily-wowed but ignorant masses with pretty bells and whistles at the expense of design maturity and reliability. To a former design engineer for the military, this is a frustrating trend. Similarly, I cannot abide the intrusiveness and privacy concerns over voice-activated devices monitored by Amazon and/or Google (or whomever). You can do all that lazy nonsense with this thermostat, but I don't want or need it. I want and need rock-solid internet connectivity and sufficient remote control for when I'm in a different state and I'm worried that the heat pump won't be able to pull enough heat out of the air to warm the house. And in this scenario, Honeywell delivers. As with all purchases, particularly electronics, there is a risk of buying a lemon or experiencing infant mortality with one or more electronic components. Fortunately for me, I saw no evidence of quality concerns with the device. It appeared well-made, competently assembled, and sufficiently documented. I do urge people to follow the instructions carefully and slowly. I suspect I moved too quickly, possibly doing steps out of order, which may have caused my wifi hiccup. Either way, it was easily corrected with the power cycle and more carefully following the instructions. I have no issues with the phone app. It works fine and allows me to do everything I want to do. It's streamlined, effective, and reliable. Surprisingly, it doesn't annoy with poor design details or irrelevant BS. (Not looking to be entertained by my thermostat. I just want the bloody thing to work and do what I tell it to do, when I tell it, without becoming a new and contrary personality in my life.) In this regard, the app has been a pleasant surprise. In summary, if you are looking for a solid performer and you value reliability over gee-whiz style and the latest marketing fad, then consider the Honeywell RTH6580WF. It's a very good value, delivering full performance at a much lower cost than most alternatives. Consider repurposing all that saved money towards something of greater life impact than a "stylish" thermostat. Good luck.

I am very pleased with the unit and it is performing exactly like I hoped, after a month of usage. Its very cool to be able to modify and monitor the temperature setting of my home on my iPhone or laptop from anywhere. Since installing it I have not yet taken a long trip away from home but I know that when I do its going to bring some piece of mind to be able to check in and make sure the house is warm and not freezing up. Scheduling: I really like the ability to set the daily/weekly schedule from the web interface. If you've ever tried setting schedules on thermostats with only a few buttons on the face plate you can probably relate to how frustrating it can be. For this unit however, the web interface through Honeywell Total Connect makes it quick and easy to make schedule changes. The app for iOS works well for this also though I prefer the regular web interface. Reliability: Once the unit was connected and happy, which took a little bit of work (see below), to date I have had no disconnects or some of the other issues reported by some reviewers. Wiring Setup: This took some head scratching but it in the end wasn't too bad. Upon removing my old thermostat, of course I found I had no "C" wire, and the labels on the old thermostat did not match the Wifi thermostat (the old thermostat had "G", "W", and and "RH/RC" wire, with only "G" matching). However I found that the instructions that came with the Wifi unit had decent enough cross-correlation for what to do with non-matching labels ("RH" was actually "R" for example). To deal with the missing "C" wire I was lucky to find a number of unused wires in the wire bundle running to the furnace with the existing wires -- I chose one and it became the "C" wire, hooking up to the Wifi thermostat on one end and my furnace (a York Diamond 90) on the other. Wifi Setup: This was surprisingly more painful then the physical installation, but once finally connected I had no issues. I had repeated "Connection Failure", error code "E02" which according to the manual means I was entering an incorrect Wifi network password -- but I was not. Through a lot of internet searching I found out my problem was I had a space in my Wifi network (SSID) name, which the Wifi thermostat does not tolerate. Removing the space from my network name solved the problem, however only after also changing my network security from "WPA TKIP PSK" to "WPA2 AES PSK" (the former is supposed to work however it would not work for me, at least with my particular router-Wifi thermostat combo -- oh well it was time to start using the better wifi security setting anyway!) Switching Wifi Networks: I replaced my old router with a new router recently (with a new Wifi network name) and tried to go through the network setup again. Not sure how to have it join the new network, I tried resetting the unit by removing the face plate from the wall, waiting a few minutes, and putting back in place -- well this only resulted in having to set the clock again and it was still looking for the old Wifi network. Tried this a few times with no luck. If I had read the instructions again I would have seen there is a section called "Disconnecting Wifi" with a particular set of key presses to have it forget the previous network and start the Wifi search again (hold down up and fan keys for three seconds, then change setting #39 to "0"). Did this and quickly had it on the new Wifi network. This is good to know how to do as I imagine you would need to do this if you changed your Wifi network password as well. The documentation is good, especially regarding installation and the wire hookups. They could add more Wifi troubleshooting hints -- it was frustrating when it was giving me an error suggesting an incorrect Wifi password when that wasn't the trouble at all. If I experience any major issues I will revisit this review but so far I am happy.

Me ayuda a ahorrar energía porque puedo programar toda la semana el cambio de ajuste de temperatura o apagado del equipo y así, si se me olvida apagarlo lo hago a distancia y si mi rutina permanece el equipo arranca cuando lo necesito y se apaga cuando no estoy.

Not easy to use also the application not work in UAE

Good quality Honeywell Controller
