I am very impressed with the Ecobee SMART Si-01 thermostat. After spending weeks reading reviews about WiFi enabled thermostats that met my requirements, I purchased this one. I wanted a thermostat that could be used at my vacation home and monitored remotely. This model connects to WiFi in your home and sends low and high temperature alerts to your email. The installation was easy and took about an hour.

I have an oil furnace with 1 stage heating and no AC. I replaced a 2-wire Honeywell mercury thermostat. The Ecobee will not run on 2 wires alone and requires a 24V power supply. Since I did not want to fuss with running a new thermostat wire from the furnace control panel to the Tstat and I needed to connect the EcoBee to a backup power supply, I purchased a power adaptor. LockState Connect LS-24VAC 24 Vac Adaptor for LS-90i. I followed the EcoBee wiring diagram for the SMART Si with external 24VAC transformer. Using this diagram, I wired the 24V transformer to the "C" and "RH" terminals on the Ecobee. I then wired the two wires from the furnace to the "W" and "Y" terminals. The EcoBee powered on and reported the correct ambient temperature, but could not operate the furnace. After more reading, I took off the cover on my furnace control panel and discovered that the thermostat wires were connected to terminals "R" and "W". I went back to the Ecobee and connected the thermostat wires to the "RH" and "W" terminals. After powering the furnace and EcoBee back on, everything worked correctly.

The thermostat is easy to operate and intuitive. EcoBee has plenty of online technical support and knowledge info. I also downloaded the EcoBee app for Blackberry and it works great. On the EcoBee web portal or with the app, you can simply change temperature and the HVAC equipment turns on. Since the thermostat is connected to the Internet, you can view outdoor temperature and forecasts from the home screen. On the web portal, you can even download the climate data (CSV file) for your home to track temperature, humidity, climate set points, HVAC operation time, etc. If you enjoy looking at data like me and playing with Excel, this is a really cool feature. All of this is free! This EcoBee model was easy to install given my simple heating system.

For people where this device will be used at a vacation home, when you register on the EcoBee web portal, enter the address where the thermostat was installed, NOT your primary address. This is not clear on the registration form. The thermostat uses this address to determine the outdoor weather.

Be aware that the SMART Si is not compatible with EcoBee smart plugs or the remote sensing module. This did not bother me.

I would highly recommend this product to anyone thinking about purchasing a new thermostat. I cannot think of anything negative about this product. EcoBee is a great company at the forefront of energy technology. I will consider purchasing other products made by them.

I had this item installed in my home today after using a Honeywell non-internet connected device. The difference is the additional control that you have upon leaving your home. Once on the road, you can set your thermostat down (or up) to maximize savings. It also runs a program to help with savings. The device looks sleek and the color screen garners attention. Overall the price is very comparable to non-connected thermostats. This device lives up to its name (Smart SI) and takes outside weather via the internet and Humidity into account when helping you to save. This is especially helpful in the southeast where humidity plays a big role in cooling your home.

I will follow up with a second review after a couple of months of usage but so far, I am very impressed!

This is my second Ecobee stat see my review for the other one here:ecobee EB-STAT-02 Smart Thermostat 4 Heat-2 Cool with Full Color Touch Screen. I have the EB-STAT-02 installed at my vacation home, and this one I have installed at my full time residence.

Although it's not as feature packed as the touchscreen EB-STAT-02, the SmartSI is, nonetheless, more than adequate for most homes.

A year ago, before this stat became available, I purchased a WiFi enabled Filtrete stat from the big orange box down the street. Big Mistake but that's another story...

Anyway, this thermostat delivers!

Ecobee's primary sales target is the professional contractor but I've found their tech support most helpful in the past. This thermostat was very easy to install though, so no tech support was required it was a wire for wire exchange. It took less than an hour to mark the existing wires, remove the old stat, install the new one and reconnect the wires.

Connecting to my home's wifi network was a simple, intuitive process similar to connecting a notebook computer or other device.

Since I already have the Ecobee web interface setup for my vacation home, adding my primary home thermostat to the same page was simple. There's a drop down box that I can select either location from turn on the A/C at the vacation home, turn it off at the primary home, go!

Not to downplay the "stand in front of it" appearance of the unit, it's downright beautiful in comparison to the Filtrete unit, but I don't see it all that much. I walk past it in the morning on my way to let the dogs out, noting that it displays the current indoor and outdoor temperatures as well as humidity levels (outdoor readings via the internet). I have, from time to time adjusted the temperature up or down a bit but for the most part, I interact via the internet. I just find it easier to sit in front of my computer and program in the home, away, sleep and wake up settings. It's a programmable thermostat provided that your day to day routine doesn't change much, you won't *need* to tweak it.

All in all, a great thermostat that I highly recommend!

Honest reviews on ecobee EB-SMARTSi-01 Smart Thermostat 2 Heat-2 Cool with Full Color

As Amazon sometimes combines reviews, I feel the need to say this is for the thermostat pictured, the Ecobee EB-SMARTSi-01... I bought this thermostat months ago and let it sit on my shelf while I contemplated all sorts of challenges or frustration attempting to install it. Wow was I ever worried for nothing. The install was a snap... it was super easy. Here's a run-down of my experience that may help you. As they say, PROFESSIONAL INSTALLATION IS RECOMMENDED... I'm just a guy, and installing this yourself is at your own risk! Be sure to power-off everything at the breaker!

1) First off, you need 5-wire thermostat wire. YOU MAY ALREADY HAVE THIS EVEN IF YOU ONLY SEE 4 WIRES AT YOUR EXISTING THERMOSTAT. Check at your heating/AC unit. You may see a blue wire ("C" on the thermostat, both your old one as well as your new Ecobee, is for cyan... or "blue"). On my Lennox unit the original install had the blue wire wrapped back around the existing thermostat wire... since "regular" modern thermostats (cheap ones) just use a battery in the thermostat itself. On my heating/AC unit, all the markings corresponded with the existing thermostat... the wire colors all went where they'd logically go... and everything in the Ecobee matched that. So it was pretty easy... yellow from the old thermostat, from "Y" in the unit, to "Y"... blah, blah, blah... simple, huh? Just connect the blue wire to the "C" at the unit, and the "C" at the Ecobee.

2) I couldn't tell at the time, but this blue wire was back behind the wall at the existing thermostat. I only saw that the house wire was 5-conductor once I checked the heating/AC unit.

3) On my house, the builder stupidly put the existing thermostat right in the sun's path through the house. So I've always been annoyed that for an hour a day my thermostat is in direct sun and makes the AC work overtime trying to lower an incorrect 90 degree reading. It was because of this that I decided to relocate the new thermostat. I didn't realize it at the time, but I could have used the existing thermostat wire... pulling it through the wall and floor, from down in the basement. This would have saved me running new wire (5-wire is cheap and name brand at Home Depot)... and this means you'll ONLY need to match up wires at the thermostat... which, if I didn't need to relocate mine... would have made it LITERALLY a 5-minute install.

4) Cut to getting everything in... all looks great, breakers back on... everything good. Take note that many newer units have a regular switch, like a light-switch, at the heating/AC unit... so you'll have the breakers in the box, plus a standard switch on the side of your unit... AND you may have (as I did) a pressure switch that disables all heating/AC power unless the unit's door is installed! You'll think something broke, but everything is fine once the unit door is back on.

5) So... the Ecobee powers up... gives me the little code as I register my unit and log into the Ecobee site... and all is right with the world. Well, almost... one thing I found is that my new Ecobee didn't show the same temps as my old thermostat. My old one was always in sync with a digital thermometer on my wall. At first I thought, "great, now I have to fool this thing with adjusted settings"... but nope, just go to Menu...Settings...Installation Settings...Thresholds...Temp Correction... then if your thermostat reads 2 degrees low, just +2 on the adjustment. Now it's perfect!

6) Other reviewers that say the Ecobee web-portal is clunky, or beta, or whatever... are you kidding me? It's CAKE... very smartly laid out. Chances are that if somebody's struggling on their site, they're way over-thinking it! To program your thermostat for the entire week (read: forever) should take you a couple minutes at the most. At the bottom of the program grid there are 4 buttons for each day... the grid matches those colors. All you do is drag the mouse across a chunk of time, like say, 8a-5p, then a box pops up so you can designate what that time is called... for example, "Away", then you can enter temperatures for ANY time that is then called Away... and so on... like I said... CAKE... it could NOT be any easier!

7) The greatest thing beyond all this... is you can lock out your thermostat. I have roommates. A long time ago I made the mistake of telling a guy to make himself comfortable before I went out of town... he literally used FOUR times the gas that I'd ever used before! I have no idea what he did... but this thermostat solves all those problems. The NEST thermostat is a learning thermostat that lets your house be a democracy. Anyone with a kid, or an inconsiderate roommate, knows that person thinks nothing of dialing the thermostat down to 50 degrees to cool off the house, then forgets about it as they leave for the day. With the Ecobee, all that is history.

8) Now I can either lower my heating/cooling bills... or rather, get more value from those expenses by taking advantage of reduced usage overnight and while the house is empty... then increasing the comfort level when it's most appreciated.

I'm very happy with this thermostat... from the ease of the installation, to the appearance and function... to the ease and functionality of the web portal... and the fantastic convenience and integration of the smart-phone app. So far I haven't been able to find one thing to complain about... and reading other reviews where somebody had a problem... apparently they gave up before finding the simple solution. One guy said the display was too bright, uh yeah... super easy to change that... I found another guy who mentioned the temp difference that I mentioned... yeah... it's super easy to change that.

I never thought I'd say that I was thrilled with a thermostat... but the reality of finally having REAL control and peace of mind over my home's comfort, and the cost to keep it comfortable... is like watching money go down the drain and suddenly somebody hands you a remote control drain-plug.

I have radiator heating and I've always struggled with overshoot, even with thermostats. Based on the reviews of others and some chatting with the company sales reps in forums, I decided to go with the SmartSi (the other option I was looking at was the Nest).

I have to say that I'm very happy with it. I enabled the adaptive mode, and on the first day it overshot by a few degrees like any other thermostat, and the next day it started the heat an hour early and cut it off after only 15 minutes. An hour later the temperature topped out right at the setpoint right on time. Sometimes it misses by a degree, but looking at the online reporting it seems to be smart enough to run the heater in little pulses throughout the day to just keep things where they're supposed to be.

Having the outdoor temperature on the screen is handy as well.

The only glitch I ran into was that it lost time during power outages (installed it right before Sandy hit). The unit recovered time quickly when it could get online. It turns out the battery inside wasn't seated properly I emailed support and they offered to replace the unit, but were fine with me opening it up myself. That took all of about 5 minutes and fixed the problem now it doesn't lose time at all if I cut the power to it.

Biggest issue DIY'ers are likely to run into is a missing common line. This has to be on the heater relay if you have separate heat/AC. If you don't know what you're doing best to hire a professional for that you can damage your heater relay if you don't wire it correctly or if you short it out.

Obviously haven't run it in cooling mode but for some testing, but if it can handle radiators I'm sure an AC will be no big deal. The unit takes into account outdoor temperature so it can anticipate how the temperature will change before it actually does.

Their support is outstanding. Email, phone, Google groups, etc. They do prefer to work through contractors though, so I'm not sure how much wiring help they'll give you due to liability concerns. So, keep that in mind.
