When there are sensors paired to the ecobee, they will take temperature readings from the locations they are placed at and report those temperature readings to the thermostat. The thermostat will then use all of the temperature readings, including its own and create an average indoor temperature. The ecobee then uses this average to adjust the temperature of the house. This is actually the temperature you will see on the main screen.

Even though the thermostat has more information to work off of, it is still not able to direct airflow to different areas in the home, heating or cooling will still affect the entire home when used.

Don't really see the benefit of these. If the room with the sensor is normally a colder room (which is why you would put the sensor there) You will be heating the whole house just to bring the temp up in that room. How can this be efficient?

Agree. Exactly what we do in our house. Just put the 1 sensor in the coldest (or hottest, depending on season) room and you're all set.

These are best used to avoid overheating or overcooling rooms when the door is closed (e.g. when sleeping), by having local temperature reading available. Sure the occupancy sensor won't help in those situations, but it can be disabled.

Can this be used as a security measure for motion detection?

If only I could get it into fan only when my kids leave the sliding door wide open during the summer... Grrr
You can if you add a door sensor to your automation setup.

Shows up as 8% for me. I uploaded a screenshot. Not sure which site you're using, as we can't mention them here. But I like to think of mine as being "tip top."

Installing, maintaining, and upgrading this system seems fantastic. Can't believe I've been pushing the buttons on my thermostat all these years like a sucker...

Best Buy chat immediately told me no when asking for price match. I then asked if they matched the manufacturer, and they said yes and matched it.

Probably a default response to say NO unless the url is on a list.

Best buy almost always pm the manufacturer. I did the same, the rep pm'd asap.

ok a few things to note hereFrownthese are my opinions and nothing more, take with a grain of salt)

cliff notes:
1. follow me = doesn't work, not good for saving energy or anything for that matter
2. sensors are great if you know how and what to use them for
3. everything is about the setup and not just plug and play.
4. new sensors battery life seems to be not as good as the old one's (might have changed with recent productions, but people complained that the battery would die in the first three months when it first came out.)
5. functions are hidden in system but can find most functions on thermostat. hard to know what does what

Long Read but worth It (trust me)

my current setup = ecobee 3 and 5 sensors setup with 2 extra incase any of the sensors go bad.

setup for me:
1. open all vents in house and install sensors where you think you might need them. start off with a min 3 sensors plus thermostat
2. cool house and check each sensors temp - reading should be + or - 1-2 degrees
3. in our case, thermostat is about 6 degrees or more colder that all other sensors and all other sensors read about 4 degrees off from each other.
4. any sensors that is reading more colder/hotter then current temperatures, adjust vents to restrict air flow to that room and test again.
5. repeat process until temps are close to each other or you get tired of testing and just give up.
6. if current temperatures cannot be close to each other, it's ok as time of day, sunlight, insulation will factor into room temp differences.
7. if on a separate level house (2 floors or more, set even temp per floor)
8. once everything is set up, let system stay the way it is, and test for the next couple of days to make sure temp on each sensor is to your satisfaction.
9. once done, continue to next steps.

setting up cooling comfort settings:
this is where it get's a little interesting as after the fist setup, most will leave it at that and say it's good, but you need to customize it a little more as different events will change our cooling needs.
if you leave this stock and set the temp on the thermostat, it will average all sensors and make the room with the most people hotter while making the other rooms ice cold.
Home, Sleep, Away, is the default settings but you need to add to this.

1. go to your comfort settings and tap on Home
2. set temp for home
3. under sensors, pick sensors that you want to be averaged in this comfort setting
4. save settings
5. add other settings depending on your needs and name them accordingly (kids Gaming, Visitors, Party)

doing it this way, you have full control of what sensors are averaged and not trapped by having the thermostat average all sensors.
yes it might not be a friendly way to do it as you have to change it depending on your needs, but at least you are only cooling the room your in and being comfortable at the same time.
we have this thermostat on google and just tell google to change it to the comfort setting we want

side note :
for the person that was asking about the auto fan on to help cool down the house without having the ac/heater on.
you can click on the setting and tap on the fan icon to turn it from auto to on or:
1. go to settings and then system
2. click on fan and enter a number from 0-60
3. what this setting does is turn on the in home fan, without turning on the ac/heater for x amount of min every hour.
this will have the internal fan cycle on and off every x amount of min every hour, even when your not home to circulate the air and try to prevent stale air inside your house.

hope this helps some, have ecobee and happy setup. it takes some time, but so worth it.

we replaced the old sensors with these newer ones at the last black Friday sale. The old ones have been redeployed into the garage, basement, shed and attic as temperature sensors. They are not part of the house temp averaging nor are they used for motion sensor. On the phone app we like to pull it up to see how hot (or cold) it really is if we were not sitting in AC or heated comfort!

Remote sensors like these are useful in very specific situations, but as many others have pointed out, do not actually change how effectively your HVAC system heats or cools. You don't need any sensor to tell you that one of your rooms is always warmer or colder, and if your AC runs extra long to get that warm room to the target temperature, guess what, the rest of your house is now freezing.

I actually found these to be much more useful simply as temperature sensors tied into my home automation system through my smartthings hub. In the summer, they turn on ceiling fans at certain temperatures automatically.

As far as their intended use though, to me they are just a very clever upsell that seems very appealing on the surface but is not really very useful in practice.

I have a Carrier Infinity furnace, originally with the Carrier Infinity thermostat/controller. Just a note, you can replace the Infinity communicating controller with a regular thermostat - I now use an Ecobee instread. The furnace control board has separate standard thermostat hookups you can use in lieu of the 4-pin Infinity ones.

One thing I lost was my full three stages with the modulating furnace, but with DIP switch settings on the furnace board I can still use it as a two stage with Ecobee, either low-high or med-hight. The other nice thing about the Infinity controller was that it could test static pressure in realtime, which was nice to tell if I was using a too-restrictive air filter, or if I had too many registers closed - but once I checked those things, static pressure never really changed so I didn't need to keep testing it.
I am afraid that switching your modulating furnace to Ecobee thermostat neglected its purpose and advantage.

Basically, you replaced a variating gas throttle dial with the on/off switch. In order to maintain a constant speed (i.e. temperature in the house) it has to frequently turn itself on and off, like a regular furnace, while the idea of modulating principle is to get the "right" amount of fuel and decrease those cycles to minimum, which should greatly extend the compressor's lifetime.
