Honeywell RTH9580WF Review: Smart Wi-Fi 7 Days Programmable Thermostat

Honeywell RTH9580WF Smart Wi-Fi 7 Day Programmable Color Touch Thermostat Review

Honeywell has been making top-quality thermostats for quite a while, and there’s a good chance your 15-year old one has been made by them as well. The company is no slouch when keeping up with the times is concerned and have a smart thermostat out now, the RTH9580WF, whose healthy mix of advanced features, contemporary style and updated security make it worth taking a closer look at.

Features of the Honeywell RTH9580WF Smart Wi-Fi 7 Day Programmable Color Touch Thermostat

The Honeywell RTH9580WF Smart Wi-Fi 7 Day Programmable Color Touch Thermostat’s large, colorful display gives you access to a lot of useful and current information such as the indoor and outdoor temperatures, humidity levels and more. Changing the temperature a degree at a time can be done from the initial screen, and changing its other options is easy to do by tapping on the corresponding tab.

If the default blue background color clashes with the rest of the room’s furnishings, adjusting it to any other shade is done in a snap.

Apart from programming the temperature, the humidity can be set as well, provided you’ve hooked up the thermostat to a humidifier to ensure a steady influx of fresh air from the outside.

The smart in its name isn’t only there because of RTH9580WF’s numerous connection options, but because of the way it learns and adapts to your temperature needs. After you set it up and a few days have passed, the thermostat figures out the most efficient way of changing the temperature depending on your input, resulting in shorter transition times and bigger savings in the long run.

There’s no dedicated away mode which would automatically track whether or not you are home, but playing around with the scheduling settings and setting the thermostat to stop working when there’s no need for it to do so is an option.

No one will definitely be using it when you’re not around, however as the thermostat is password-protected and can be set to respond only to input via the app.

Unlike some modern thermostats that can only be connected to a specific smart device, the RTH9580WF can be controlled via phone, tablet or PC thanks to Honeywell’s comprehensive solution. The app that’s used for this can also be set to receive notifications whenever the device isn’t connected to the internet anymore.

While the act of installing the RTH9580WF is simple enough, it can’t be performed without there being a C wire first. Some existing thermostat setups already have it; if yours doesn’t you might need the services of an electrician.

While putting a C wire in can be expensive, the upside to this is that the thermostat’s Wi-Fi connection will be greatly strengthened by it, all but eliminating connection breakups other models suffer from.

If the thermostat does lose connection, there’s no way of establishing it again without manually reconnecting the device. Most home users will have no trouble with this, but it can become a real inconvenience for vacation homes or rented properties where renters are locked out of using it.

A bit more effort could have been put into the temperature sensor as it tends to be slow in picking up on temperature changes before taking actions to compensate. Room temperature can drop as much as three degrees before it kicks in.

While most people won’t be affected much by this, elderly people who have a weaker circulatory system as well as people who insist on keeping the temperature constant might take issue with this.

Pros

  • Password protection and touchscreen lockout add to the device’s security
  • Customizable screen color assures the thermostat will look good in any environment
  • Wide range of accessibility options and nuanced alerts
  • Ability to efficiently raise and lower temperatures to your desired settings, saving on energy and maximizing comfort
  • Capable of controlling a ventilation system and a humidifier

Cons

  • Can’t function without being connected to a C wire, which can be expensive to install if not already present
  • Has to be manually re-connected to the internet whenever it loses connection
  • Built-in sensor can be slow to react to temperature shifts

Conclusion

All things considered, the Honeywell RTH9580WF Smart Wi-Fi Thermostat offers a good variety of features for the mid-range price you’ll have to pay.

Its security is way above average, as is its overall presentation and connectivity. Other important aspects like reduction in power consumption and programmability don’t lag behind much either.

It’s the perfect thermostat for an undemanding household and for owners with new homes where the required C wire is more likely to be present. Amazon Alexa integration will help tech enthusiasts get a kick out of it, and your grandparents will pick up the touchscreen’s controls in no time too, making the RTH9580WF a state of the art gadget the whole family can benefit from.
