Question 1

What is the difference between the smart sensor and the room sensor?

Accepted Answer

The smart and room sensors do not use WiFi. They use an RF connection with the thermostat. Company descriptions indicate a 65' range  for the smart sendor vs. a 45' range for the room sensor. The company stated in a pro training session that the actual distance can be farther depending on material (walls, etc.) attenuating the sensor signal to the thermostat. I believe the company rep also stated the response of the smart sensor is much faster than the room sensor (something like 5 seconds vs. a minute or two.) And yes, the battery can last much longer (approximately 5 vs. 1 year)

Question 2

Has anyone used both the old sensor (came with Ecobee 3) and this new one and noticed a difference? What is better during real world use?

Accepted Answer

I have both the room sensor and the smart sensor, 2 each. First the difference, room sensor cannot detect occupancy but smart sensor does, if you have follow me setup you’d have better results if you use just the smart sensor. Battery life is about the same given smart sensor uses the more expensive and higher capacity CR2477 VS CR2032 on the room sensor.

Question 3

Does this model work with ecobee3 lite?

Accepted Answer

I also had issues updating the firmware on the 3 lite. Customer service was able to push and I was then able to pair without any problems. Working great now!

Question 4

Do we need more sensors to place 1 in each bedroom or 1 is enough?

Accepted Answer

It depends.  We have a 3 bedroom home but since it’s just me and my wife, mostly only one bedroom gets used. However, one of our adult children visits about once a month and uses one of the bedrooms a couple nights while he’s here. So, we have a sensor in that bedroom as well. But, that sensor only participates in “sleep” in the schedule, so it only pays attention to that sensor at night.  If you use every bedroom in your house, you may want a sensor in each. Or, you may determine that generally speaking, whatever the temp is in your room, the other rooms may have the same temp, so you don’t need the extra sensor(s).
