Which one should I buy? ecobee4 or Nest Learning Thermostat

What do you do every day with your thermostat especially in the winter? are you like me whereby you manually adjust the thermostat on a daily basis depending on the time of the day you are at home?

Currently I have a Honeywell thermostat.













I have to manually adjust the thermostat to 67For 19 Degrees Celsius at night when I go to bed and I leave the thermostat at this temperature during the day when I go to work. In the evening when I come home from work, the main floor (my living/dining/kitchen areas) is a little cold as I leave my window opened a little to have some fresh air inside my place.  So I crank up my thermostat to around 72F or 22 Degrees Celsius.  I repeat the manual adjustment of  my thermostat everyday until one day I heard that with a Smart Thermostat, you can save energy (up to 23% in the cost of heating and cooling per year.  This in turn saves you money as you spend less in utilities.

In addition to saving energy and money, you can also get a $100 Rebate for Ontario  Homes.  The rebate applies to those who live in a house in Ontario.  Recently the rebate has been extended to those living in condominium or apartment in Ontario.  If you rent and you’d like to explore the SMART Thermostat, you must get consent from your landlord to participate in the SMART Thermostat Rebate.

The Rebate program is administered by IESO (Independent Electricity System Operator’s).  50% of the program is funded by Green Ontario Fund  and the other 50% is funded by IESO.  The rebate program was launched on December 13, 2017.

I wish I have SMART Thermostat at my place.  After hearing about the benefits of having Smart Thermostat and the $100 Rebate for Ontario residents, I started to do some research on the types of Smart Thermostat.

BIG Questions that everyone has when it comes to deciding on a Smart Thermostat:

  • ecobee4 or Nest Learning?
  • Is it easy to install? which one is easier to install?
  • Is my thermostat compatible?




  • Comes with One FREE Room Sensor Compatible
  • 3.5% Touchscreen
  • Save up to 23% on heating and cooling per year

  • Smart thermostat is Connected to WIFI. Control from anywhere anytime (from iOS/Apple Watch or Android devices.)

You can also purchase extra ecobee Room Sensors which comes in a pack of 2. The Room Sensors pair with ecobee to help manage hot/cold spots in the house/condo.

Click on the Room Sensors image below if you’d like to buy the ecobee Room Sensors. In my home, my main floor is always colder and upstairs bedroom is warmer. with the room sensor this will help provide comfort at the right temperature.

If you prefer to save money, you can also purchase an older version of ecobee (ecobee3 lite). This is also eligible for $100 Rebate.

Tip:  make sure to do a compatibility check to see if your thermostat wiring is compatible with ecobee4 before purchasing one.

My friend installed Nest Learning Thermostat in his condo and he likes it as it learns your patterns on how warm or how cool you like your home. Once Nest Learning Thermostat learns your patterns, you hardly ever have to touch it.

Nest Learning Thermostat gives you data on the past month.  It did not keep stats or reports so it is hard to see how things trend from the past several months or more.

Below are the Differences between ecobee4 and Nest Learning Thermostat

Features ecobee4 Nest Learning
Amazon Voice Service built inside Yes No
FREE Room Sensor Yes No
Warranty 3 Years 2 Years
Learns Habits over time No Yes



It seems like ecobee4 Smart Thermostat has more features than Nest Learning Smart Thermostat.  I would pick ecobee4.

However, if you like the fact that Nest Learning Thermostat learns your habits over time and automatically schedule the thermostat, then Nest Learning Thermostat is the one for you.

How to apply for $100 Rebate if you live in a condo or an apartment:

  1. Check if the thermostat is compatible with your  home.
  2. Purchase and install one of the eligible smart thermostat models. (ecobee4, ecobee3 lite, ecobee3, Nest Learning Thermostat, Nest Thermostat E)
  3. Connect your smart thermostat to Wi-Fi then register your smart thermostat with the manufacturer online.
  4. Submit your rebate application through the manufacturer’s rebate portal:
  5. The manufacturer will send you a rebate cheque of $100 in 8 to 12 weeks. Cheque will be payable in Canadian Dollar to participant and mailed to address provided on the Rebate application.  The cheque must be cashed within 6 months of issuance.
