Smart thermostat maker Ecobee has just announced a new free update called eco+ that it claims will save you even more money when you use one of its devices. Ecobee is first rolling out eco+ to its latest product, the SmartThermostat. It'll push the update to its other thermostats -- including the Ecobee 4, Ecobee 3 and Ecobee 3 Lite -- starting in early 2020. To get the update, you'll need to download the latest version of the Ecobee mobile app.
Eco+ consists of five separate features that you can enable independently of one another. The one that likely has the greatest potential to save you money is called Time of Use. When enabled, this feature will, like its name suggests, attempt to take advantage of time-of-use electricity rates to maximize efficiency. It does this by precooling or preheating your home when electricity is more affordable, and cutting back when it's more expensive.
The other major potential money saver is called Smart Home and Away. It will automatically adjust the temperature in your home when you're not there. This feature was available on Ecobee thermostats before today's update. However, the company has improved so that it works faster. Previously, it took approximately two hours for an Ecobee thermostat to confirm you weren't at home. With Eco+, it can now do that in about an hour.
Then there's Schedule Assistant, which will recommend changes to your heating and cooling schedule. If you've used a Nest thermostat anytime in the past couple of years, the concept of automatic schedule adjustments will be familiar. Where Ecobee's execution differs is that one of its thermostats won't make a tweak unless you first approve it. Ecobee says it doesn't want your thermostat surprising you.
Another new feature called Feels Like will measure the humidity in your home and adjust the temperature as needed. Lastly, there's a feature called Community Energy Savings that will make micro temperature adjustments based on when demand for electricity spikes in your community. Ecobee claims this feature can reduce strain on the electrical grid.
How much money you can expect these features to save you money will depend a lot on your home. According to The Verge, in an independent study Ecobee conducted of 250,000 customers, the 120,000 using eco+ were able to save on average an additional six percent on their HVAC costs. That's in addition to the 23 percent the company claims its customers are already saving.
Update 2:40PM ET: This post has been updated with additional details on the study Ecobee conducted about how much money eco+ can save users.
