  • Great Addition to Our Winter Vacation Home
  • December 27, 2013
  • Recommended Product

For years we've been driving up to our vacation home in Truckee at North Shore, Lake Tahoe, CA and in the winter the house was cold and took forever to warm up. Now I set the thermostat to the warm temperature that we like before we leave and when we arrive the house is toasty warm.Easy to install with good instructions and great on-line video. Once installed, super easy to program and set up the wi-fi account. So far it has worked flawlessly.After much research I selected this model because I wanted touch screen but didn't need all the bells and whistles of the $200+ models.I am recommending this wi-fi thermostat to all my mountain friends.

I was interested in this thermostat for the wifi connectivity and with the hopes that it could save me money on energy costs. It's too soon to decide that yet, but I'm not sure if it will.First of all, the overall quality of the thermostat is great. It looks nice (THOUGH IT'S HUGE), and is easy to operate either from the device or over the internet. It has a back-lit LCD display that always glows a reassuring electric green. The device is nice but it draws the eye to it and doesn't fade into the background the way you would want a thermostat to.Installation was easy, though I was missing a power line from my furnace (my last thermostat didn't require one but it was buried in the wall) so it took me a bit longer to install then it should have. Once installed I grabbed a laptop and logged into the thermostat and then onto the web to set it up. This process took about 30 min in total as it downloaded an update to the device that took about 10 min itself. I've never been a big fan of the programmable thermostat because it always seemed to take more time to set it up then it's worth. The setup on the web was straightforward and simple so anyone could figure it out, though if you're squeamish about technology you may want to have someone else walk you through this process. Overall this was the easiest time I've ever had programming a thermostat.The website asked for more information than I would normally give out (wanted home address, name, phone, etc.) and there's no mention as to what data they're collecting and tracking, but I'm sure they're doing it. And the web app really only lets you set the schedule for the thermostat. It does tell you temperature inside and outside and can email you on events. It will notify you if the temperature drops below a user specified threshold for a certain amount of time, or it can notify you on any event you'd like (fan goes on/off, temp changed, etc.). Could be a nice feature if you're concerned about others constantly changing the temp. Aside from that there doesn't seem to be much added functionality from the wifi connection, though it is really nice to be able to set the temp from my phone whether I'm in the house or not.Essentially this is a rather large programmable thermostat that you can access remotely. It's nice, but aside from the ability to program it remotely there's not really much added value over a less expensive and smaller programmable thermostat.I'd recommend this for the household that wants to micro-manage their heating/cooling. If you're someone who wants to set up a thermostat and forget about it you should probably just get a less expensive model without the wifi. Hopefully Honewell will include some software in the future to allow you to monitor energy use a little better or even to integrate it with data from your Utility so you can get more out of it.

Also, it's not on web description, but it can control up to 2 stages of cooling and 2 stages of heating. You'll find that in the System Set Up section of the user guide.

The installation of the Thermostat was easy enough. Remove the old thermostat and mounting plate. use the included decals with the new thermostat to identify the color of wire to the correct terminal (don't rely on colors)The only "snag" i had was I did not have a dedicated "C" wire. I talked to a licensed pro for a work around, since pulling new wire was not an option. you can remove the "G" (fan) wire on the thermostat terminal and use it as the "C" wire. then on the furnace terminal you remove the "G" wire and also place it on the "C" terminal. THEN you have to make a jumper from the "Y" terminal to the "G" terminal on the furnace. This is so when the fan or AC kicks on it will also turn the fan on.The only down side to removing the "G" wire option is that you can no longer turn the fan to "on" it will work as needed and as normal when in the AUTO mode when the AC and Heat come on. i never just used the fan without the heater or AC so it made no difference to me.The only other issue I had was connecting the WiFi. when i was selecting my home network i kept getting a "REQUEST TIMED OUT" error. I finally just registered the thermostat online and the thermostat connected just fine, however it still shows on the network connection page as "REQUEST TIMED OUT" even though it is connected. My advise is to open the network connection page, enter your password, then register your product. do not wait for the network page to say that the devise is connected. mine still doesn't.Using the App is nice and convenient. i tend to use this more than the online option. I've already had to use it when the temperature dropped while we were gone. I was able to turn the heat on so we did not come home to a cold house.

  • Router issues
  • December 07, 2012
  • Recommended Product

First, the thermostat works well. However, the issue I had is in use of my NetGear router. The router was dropping the signal on an average of once every three days. I learned that's a common issue with some routers. The router would still be working, but the WIFI on the thermostat would get confused and disconnect the signal. It is unable to re-engage automatically. The thermostat system could only be reset if I unplugged the router for a minute or two and reapplied the power. Not very useful or convenient if your on vacation. I looked into getting some programming patch for the router, however, one idea I picked up by reading other websites was to purchase a simple ordinary lamp timer that can be purchased from any home improvement store for around $10. Set the timer to turn the router off for 5 minutes, once or twice a day, and then have it reapply power. It resets the router and the WIFI signal on the thermostat is restored. It's that simple.

  • Issues with long WiFi keys, but otherwise a great device.

The installation booklet is very complete. It should cover most common HVAC systems at home. I have a system installed in 1985 with a newer heat pump about a decade ago. It took me a while to work out the Aux/E connections, but everything seems to work.Setting up WiFi was where I encountered my first problem. The system is very simple and the user only needs a WiFi capable device (laptop, tablet, smartphone, etc.) You connect to the WiFi network created by the thermostat to select and configure your WiFi key. (You do secure your WiFi, Right?!?) You can then paste in the WiFi key. We use a PKA network with a 63 character key. The thermostat only accepts up to 48 characters for a key. So the only way I was able to connect to my network is change my router's key (and I will have to re-enter this key on 18 other devices who can handle a 63 character key with no problem.) This is a big fail.Being a programmer by career, I decided to do a little hacking on the web page of the thermostat. Using Firefox and the Firebug add in, I enabled the Console and reloaded the thermostat page (192.168.1.1). Then I opened the network pulldown for my local WiFi to reveal the password textbox. This textbox has an HTML id of passp. I executeddocument.getElementById('passp').maxLength = 64to set the maximum length allowed by the textbox to the real value for a WPA key. This allowed me to paste in my full 63 character key and the thermostat connected to the network fine. To artificially limit the web interface for the key is just idiotic. I wrote to Honeywell and told them just that.If you have a WiFi key of 48 characters or less, you will not have a problem setting this up. In those situations, it is a brilliant configuration method.Once I setup my smartphone app and connected to the thermostat, it downloaded a software update to the thermostat.I like the ability to set Heat and Cold to Auto. This will switch between Heat and Cold mode as needed to maintain the temperature above the Heat setting and below the Cool setting. (Min of 3 degrees must be between the settings.) This is great for the spring and fall weather that normally has us switching between modes almost every week. I find this more useful than the WiFi capabilities of the device!Setting update using my smart phone app to the cell network (not local WiFi) takes about 5-20 seconds from submit to updating on the thermostat. I occasionally get a web service error from the app, even though the setting was changed. I've had it change on the thermostat, but time out on the app, so it shows the previous setting. If you have this occur in the app, exit and go back in will load the current data from the thermostat.Setting up schedules on the web page is no contest compared to manually working the data points on my old t-stat. Nice improvement.The registration of the device allows you to set other functions like emailing you when the temperature is over or under a set limit for a set time. You won't be surprised with broken AC or Heat when you get home.All in all, I'm really happy with this now that it is setup. Very slick device. If the setup issue was addressed by Honeywell, this would be a 5 star device.

  • If you are having trouble enrolling on your home network...
  • November 11, 2012
  • Recommended Product

after installing the unit, I spent 2 hours trying to enroll the thermostat into my home network with no luck. I then found out that any apple device that has been upgraded to IOS 6 will not be able to enroll the unit since the thermostats were manufactured with firmware that was before IOS 6. I used a PC laptop, found my home network, enrolled, and by the time I was finished, the new updates had been sent to the thermostat from Honeywell's website which allowed me to now use my apple devices (ipad, itouch, iphone) to control my new wifi thermostat. Honeywell should add this information to their youtube enrollment video in the comments section. Hope this information helps others out there.

  • Great thermostat - Great App and PC Interface
  • September 12, 2012

Came close to buying another WI-FI thermostat from HD but decided to wait for Honeywell to enter the consumer market with an affordable WI-FI product. They are "spot-on" with the RTH8580WF. Easy to configure and the app interface makes it a snap to use. True Auto Heat/Cool changeover which is absolutely necessary where A/C and Heat can both be needed at varying times of the year. (Fall and Spring in the Austin area often go from boiling to cold on the same day). The thermostat shows both the Heat setpoint and Cold Setpoint so there is no need to toggle between them (big display with smaller numerals/letters than I prefer). Probably the best feature is having the ability to change the temperature from a smartphone via internet app (available for android or iphone). We travel a lot and hate coming home late to a hot home. Now, with the click of a few keys on my smartphone, our home is cool upon arrival. Buy the way, do not forget that a "C" wire is absolutely necessary for this thermostat to work. The "C" wire is the grounded side of the 24V AC transformer that is the control voltage for your A/C - Heating unit. If none of what I just said in the preceeding sentence makes sense, outsource to a HVAC installer or get help from a knowledgeable friend.

  • Horrible customer support
  • January 09, 2014

I bought one of these and installed it several months ago. At first it worked great. However, after several months the screen failed. The thermostat is still functioning but I need to use the app on my iPhone to adjust the settings. Taking the logical approach, I reached out to Honeywell to try to correct the issue.In summary, after 3 months and countless emails, I'm still in the same position. Their support individuals first had me try several things to correct the problem. These did not correct the issue and I was then refered to the warranty supervisor (it was within the warranty period). Multiple attempts over 4 weeks to contact this individual have gone unanswered. I then tried reaching out to the support organization who told me that as the case had been refered to the warranty supervisor I needed to follow up directly with him and there was nothing they could do. 4 more weeks have gone by and I have no response from this person and additional attempts to get Honeywell to help me in some other way have all gone unanswered.I can only conclude they do not stand by their products. I'm about to replace 2 other thermostats and would like a product such as this but I will pruchase one from a competitor. I'll also be replacing this unit.

Easy to install and works perfectly. I never lost the connection. Even when I lose power, it reestablish the connection by itself once the power is back on and it keeps running the schedule normally. I think the people with connection issues might have a problem with their WI-FI settings and not with the thermostat. The smartphone and tablet app works perfectly without any issues. The app is very convenient and a money saver.I have it for almost a year know and it still working sharp.
