Honeywell Wi-Fi Smart Thermostat Review and Giveaway

In January, Honeywell contacted me about doing a review of their RTH9580WF Wi-Fi Smart Thermostat. I agreed and received the unit a few weeks ago, installed it, and have been using it for about 3 weeks. The following is my review of the product, and at the bottom, you’ll find giveaway information (Honeywell is giving one unit away to a lucky winner).

Compatibility Test

The first thing I had to do before participating in this product review and giveaway is to make sure my current system is compatible with the new Honeywell thermostat. Honeywell provides an easy to follow guide on how to do this. You should check out this guide if you’re planning to participate in the giveaway (you have to verify that your system is compatible). Just as an FYI, my system doesn’t have the C wire, but has an extra wire that works with the thermostat — so I was good to go there.

Installation was a little more challenging. I tried to do it myself, but soon realized that the extra wire that I have wasn’t connected (so the thermostat won’t power up). I didn’t want to damage my HVAC system in the process of connecting my thermostat, so I called in the pro. He replaced my thermostat and re-configured the wiring in the basement…and viola…we are good to go!

Once the system powered up, the next few screens walk me through the system set up and Wi-Fi configuration. It took me about 10 minutes to do the initial set up, including set up an account online and download the iPhone app.

I upgraded from a very basic manual thermostat, so there are a lot of things that I like about this Honeywell unit.

  1. Control the thermostat from anywhere using a web browser…or my iPhone.
  2. Fully programmable 7 days a week.
  3. Run the fan on Circulate (which randomly turns on the fan for 15 minutes every hour).
  4. Shows inside humidity in addition to the temperature.
  5. Shows outside temperature and humidity.

To the right is a screen shot of the iPhone app, which happens to be my preferred way of setting up the scheduled. I find it the most user friendly option of the three (vs. set up on the thermostat itself and on the web).


As part of this review Honeywell is giving away one RTH9580WF Wi-Fi Smart Thermostat to a lucky winner. The giveaway is open to US and Canadian residents and your system must be compatible with the thermostat, check here. To participate, please follow the instruction below:

  1. My current thermostat has black LCD display. It tells you when it is time to change the filter. This one looks a lot more useful and stylish.

  2. My current thermostat might be from the turn of the century. We’re in desperate need for something more user-friendly that works always!

  3. I always thought it would be cool to control the thermostat from my phone. When I leave my home I try to turn off the AC or heater if its reasonable to do so; however, I often forget. If I had control powers on my phone I would be more likely to remember. This would help me reduce bigger costs. Interesting to hear how this system is working for you!

  4. We have a reasonably smart thermostat, but it cannot be accessed over the internet. I have our thermostat programmed so it drops the temp to 65F at night, raises it to 70 in the morning when we eat breakfast, and then drops it back to 65 when we are at work. Then turns the heat back up in the afternoon/evening when people are at home. Of course I change this in the summer, with the heater off and the AC on.

  5. We have a digital non programmable. It’s ok, but I never remember to turn it down at night when we’re going to bed.

  6. This would be a great gift for my mom in mother’s her house thermostat is so old and doesn’t have features like this one !!

  7. My current one is about 15 years old, it came with the house. Hubby is on a massive automation make over and I know this would make him very happy

  8. Thank you for this article – great timing as I was spending the weekend researching this one vs. the Nest. After all of my research, I will be purchasing (hopefully winning!!!) this one…it meets all of my needs for a better price.

  9. We currently have a Honeywell programmable thermostat. We love the convenience of set and forget. But time for an upgrade!

  10. ours now is just plain and doesn’t have any programming options available. I would love to be able to set this one over wifi

  11. We just recently purchased our first home, and we’re comparing the Nest and the Honeywell. My uncle (a HVAC guy) thinks they’re overkill, but if I have to deal with terrible kitchen configuration for a year until we can redo it I want at least one shiny toy (also: how old am I when I’m this excited about a thermostat?).

  12. the one I currently use is old and I have to push the buttons really hard to get it to work. I love this one. I love that It can be controlled anywhere
