  • Great product that requires patience and TLC
Disclaimer: So I admit up front that I had to give this device a lot of TLC and have a considerable amount of patience to get it to work for me. However, the tweaking, researching, and correcting was worth it. I really love this device and it has made my life easier. One awesome thing about the thermostat is that it has SO many options that you can customize to fit your variables. On the flip side one of the most frustrating things about this device is that it has SO many options that you may feel overwhelmed, confused, frustrated and lost. If you hate technical things and struggle with patience then this device may not be right for you. But if you purchase it with the understanding that it will take several days to tweak and adjust to your variables then you should end up loving it. Word of advice - try and solve one problem at a time - meaning reduce variables to get one piece working and then focus on the next variable - if you try and adjust the thermostat and have multiple sensors attached then it will make it more complex. Also - I have had great customer service in my interaction with the company. After a 15 minute wait I get a real person on the phone that is helpful, friendly and willing to make things right. Their communication is top notch. I find their knowledge base on the website a little hard to navigate - but it has answered many of my questions - so while is not super efficient it is effective. Background: We are a family of four in a 2 bedroom apartment in Texas. The apartment had a mercury thermostat on the wall which was hard to read. I replaced it with a Honeywell digital thermostat which worked great until we had kids. My wife started to worry about the temperature differences in our room vs. the kids room at night since their room tended to be cooler or hotter at night in the winter or summer. Plus, as anyone in the south can attest, our weather can seem all over the place and we constantly had to guess on if we should set the thermostat to heat or cool each night before bed - which is one of those grappling 1st world problems we had to deal with. :0) We purchased a nest thermostat and returned it within a month. The two reasons why we returned it were (1) we could not see the actual temperature of the room and (2) it had to get past the set temperature by a degree before it would finally kick on the air or heat. My wife complained enough that I was at a loss and determined I needed to do more research. I looked at several other options from Honeywell and other thermostat manufactures but after reading tons of reviews finally decided to purchase the Ecobee3. Installation We have a regular HVAC that is basic and not very complicated. (1) Fan (2) Heating (3) Cooling. I went to my breaker box and turned off the power to the heat and cool. I uninstalled my old thermostat and found 1 white, 1 yellow, 1 green, 1 red and 1 blue wire running through the wall from my HVAC to the thermostat. However the blue wire was not connected to the HVAC while the other wires were. I discovered that this blue wire was necessary for the installation to give constant (C) power to the display of the Ecobee. Not having much electrical engineering experience, I went to my HVAC and took a picture of how everything was connected and sent the picture to Ecobee's customer service team. I then called them up and asked them to look at the picture I sent and help me figure out where to connect the blue (C) wire. They were super friendly and helped me figure it out. I had it connected within 15 minutes. I used the included circle back plate since the old thermostat was covering an electrical breaker box. I then connected the red, yellow, white, green and blue wires to the Ecobee back plate and screwed it into the wall. I flicked on the power and everything powered up. Walked through the initial setup of wifi and registration and was on my way. Thermostat Things I love about the thermostat: (1) The display is SUPER easy to read - and it displays the actual temperature. (2) In auto mode you can make the difference between cool and heat 2 degrees (2) When the temperature in the room reaches your set point it begins cooling within 0.5 of a degree - it doesn't have to pass the set point to turn on the cool or heat. (4) It is touch screen and really easy to navigate and adjust (5) It is closer to the wall and is more attractive than the Nest Tweaking I had to do: (1) When we first got the thermostat it's built in sensor was reading hotter than the temperature on the wall next to the unit. And when the air kicked on it would fluctuate cooler about six degrees within 5 minutes of the air coming on. It seemed really buggy. I was really worried. I called customer service and they explained that air was running from under the thermostat into the wall and affecting the sensor. This made sense to me because the back plate had many openings on the back that would let air go straight up the wall - especially since I had an empty electrical box sitting back there. They recommended that I go and pickup some plumbers putty and seal the holes to prevent air from running up the wall and past the sensor. It was a pain in the butt, but I went to wally world and picked some up for a couple bucks. I then took off the thermostat and used the putty on the back of the base plate. I covered every place where air could escape leaving the screw holes and spot for the wires open. I then screwed the wall plate on the wall and re-attached the wires. I then used the plumbers putty to cover the screws and surround the wires so no air could run back unto the wall. Plumbers putty is non-conductive so I didn't have to worry if it got on the wires - but i still was really careful. This fixed the issue completely. The sensor now reads the correct temperature as I used my infrared thermometer to measure the temperature of the wall next to the thermostat. After reading several reviews here on Amazon several people have complained that the sensor on the thermostat is higher because of the heat of the screen - but my experience has proven to me that the reason the temperature was reading higher before was not because the screen was hot - but because air was rushing past the sensor up the wall. My thermostat sensor is now very accurate and I am very happy. One other setting I adjusted on the thermostat was only having the air or heat come on for 1 minute if needed. By default it comes set to 5 minutes of heat or cool - but I didn't want it to always blow for 5 minutes even if it had hit the desired range. Again - it is cool that Ecobee allows this to be adjusted. Sensors: One external sensor comes with the Ecobee and I purchased a two pack of external sensors separately bringing the total sensors on my system to 4 (Thermostat sensor and 3 external sensors). The sensors are a really cool feature and satisfy the worry that my wife had about our rooms being different temperatures at night. However, they are really confusing because of the way that they work. If you have the "follow me" feature enabled or disabled also adds to the complexity. There is a 3 min delay on the web portal and app from when changes are sent to the thermostat and then to Ecobee's server. So the sensors are great when they are actively being used and have about 30 minutes to adjust. Things I love about the sensors: (1) replaceable battery that has a estimated 4 year life on a cheap battery (2) comes with a stand or you can mount it on a wall (3) tracks temperature and occupancy (4) you can attach 32 of these suckers (5) you can select which sensors will be used for each activity What I have learned about the sensors: (1) if you have them checked on as part of your activity then they will average across all rooms (2) they only send their data to the thermostat every three minutes (3) if you touch the sensor it will read high because of your body heat (4) Until the sensor is actively used in an activity it seems to not send updated data to the thermostat (5) You can only delete a sensor from the thermostat not from the web portal or app (6) You can reset a sensor by flipping the battery and letting it sit for 5 minutes (to drain the capacitors) and then flipping the battery back over (7) The sensors work up to 45 feet from the thermostat - even through walls (8) one of my sensors disconnects and reconnects a lot, but I haven't troubleshooted it yet with tech support (9) I read that if you take out the battery and pull up the little metal contacts under the battery it shouldn't disconnect as much? (10) the sensors gradually adjust so that they don't drastically affect the air turning on and off - but this can be frustrating because it may increase your average temperature for a while. (11) the temperature on your thermostat and devices/web portal will list the average temperature when a sensor is being used - which can be confusing. (12) there is a place on the thermostat on apps/web portal to see each individual reading for each sensor - but again - it takes time for that to sync up with the thermostat and company servers. (13) I found on the web portal that I had to save my changes for each sensor several times and refresh the page before it would finally sync up and save and then start using my setting. Overall Recommendation: Yes I would get the Ecobee! It took a while to setup and adjust but now I don't have to think about it. ... show more

  • It's a Keeper!
Nearly twenty years ago I purchased a programmable thermostat with individual schedules (both heating and cooling) for each day of the week and happily installed it in my home. The stat was time-consuming to program, so the on/off switch was frequently used as a substitute for effective scheduling. Instead of a 'C' wire it employed two 'AA' batteries to provide power to operate the backlight for the screen and to maintain the settings, a very good thing considering how much time it took to set each of the daily schedules. There were no settings other than for the schedules and a filter change timer, but at the time I suppose it would have been considered 'cutting edge'. After considering the Honeywell, Nest, and Ecobee3 I chose the Ecobee3 and was one of the last 'lucky' people to pay the full price for it before it went on clearance. Purchased with the stat were an additional two remote sensors, probably unnecessary in my present house since there is really only one room other than the living room where I desire temperature control (the main bedroom, which tends to overheat because of poor air circulation). However, being somewhat of a technology lover I am experimenting with a sensor located on a table next to the couch so that the living room temperature can be controlled at that level while the wife and I are watching TV or movies. Why don't I just change the set-point to accomplish the same thing? I own the sensors, so I might as well make use of them. Mounting and wiring the Ecobee3 was a straight-forward task, but then I have spent the last thirty-five years working as a temperature controls technician and systems programmer. Don't worry, though; you won't need all that experience. If you don't have a 'C' wire and your stat cable doesn't have a spare wire for you to connect for that purpose, Ecobee3 has you covered. Included in the box is a device that will give you a 'C' wire using only your existing stat cable. Once the stat is mounted and powered it is time to pair it with your network router. You don't have a router? Well, in that case you will be limited to local access, meaning you will have to access the stat from its own display for any and all data input and you will not be able to remotely access it from a smart-phone. You won't have an on-screen weather forecast, you won't be able to geo-fence (explanation forthcoming) and you won't have access to the Ecobee3 website with its usage data. Even without remote access the Ecobee3 is a wonderful programmable stat, but face it: I bought it so I could get online with it from anywhere. Once connected to the internet a whole new world opens up. I have my geo-fencing set up based on my travel distances and comfort settings. If you are unaware of geo-fencing it is a method of setting your stat to 'away' and 'home' mode based on your distance from your residence. In order to use this technology you must have a smart phone assigned to your stat's account and you must carry it with you as you travel. The phone must be set up to broadcast its position. In determining a geo-fence diameter you should consider how much time it will take to recover from the 'away' settings and how close to your 'home' settings you want the house to be when you walk through the door. A geo-fence event occurs when your phone moves outside the fence area and another event occurs when your phone moves back into the area. Since those two events are distinctly different, one of them can trigger your Ecobee3 to transition to 'away' mode and the other can transition it to 'home' mode. A really nice feature of the Ecobee3 is the vacation scheduling. An alternative to geo-fencing, vacation scheduling will set your home to 'away' mode at a pre-determined date and time and then return it to 'home' mode at another pre-determined date and time. Multiple vacation schedules can be set up ahead of time and will not be forgotten by the stat. Smart home and away is yet another method the Ecobee3 uses to help save energy (and money). The thermostat and each remote sensor has an integrated occupancy sensor which can trigger 'away' or 'home' modes based on occupancy. If the system is indexed to 'away' mode and one of the sensors senses movement the system will temporarily switch to 'home' mode. Conversely, if the system is in 'home' mode and no movement has been detected for a couple of hours it will switch to 'away' mode. The system can also be switched manually either at the stat or via the smart-phone app. I find it interesting to look at my sensors with my smart-phone and see that they are following my location accurately. Changing the active set-point manually can be done at the stat or by a smart-phone and you can choose to keep the override until you change it back or else allow the next change of schedule to change it automatically. The Ebobee3 can be controlled by "Alexa" via an Echo or Dot, but I don't have either of those devices and therefore cannot give an opinion. There are numerous settings for fine-tuning the control of heating and a/c systems and the stat does an admirable job of doing the control. The Ecobee3 keeps my house at a more consistent temperature than the old stat did, probably due to the smart recovery options that I have turned on. Yes, the Ecobee3 costs way, way more than a twenty-five dollar programmable unit and to some folks that is enough to dismiss it as totally unnecessary; but, I think it will result in savings over time, maybe even enough savings to pay for it. So far I haven't found any down-side to this stat, in fact the programming is so much quicker and easier than with the old stat that I actually use the scheduling now! And if it doesn't pay for itself? I will still like it and still recommend it. Here are some things that could be added to the Ecobee3 that might make it more appealing. Combination camera/remote-sensor modules that could display video across the internet. A method of using the occupancy sensors to trigger intrusion alarms. A more attractive smart-phone app. Really, the app is rather dull looking and there is no option available to spiff it up. It would be nice to be able to use photos or video feeds as wallpaper so that you would see your house when you sign on, and see individual rooms when clicking on a sensor. Instead all you get is a white-on-black display that looks like the stat. OK, there is a little bit of orange and blue to signal heat or cool, but practically speaking it's white on black. This is an area where I think the Nest wins, although it's app isn't exactly a masterpiece either. The Apple HomeKit integration is wasted on me since I don't use an iPhone, but for others it is a definite benefit. I would like to see the screen colors be selectable instead of set-in-stone white on black. I think that is enough of a list for now. None of those things is a deal-breaker or deal-maker since this stat is worthy in its own right. From what I understand, everything that I have said here would apply equally to the new Ecobee4 since it is essentially the same stat with the addition of Alexa functionality. Shopping for a smart thermostat is an exciting adventure, but finding the perfect fit is not so easy. Each stat has functionality that the others don't have, which means that the one eventually chosen will probably be missing something you want; but, in the end you will end up with a vastly better stat than the one you remove. Edit August 23, 2017. I set my Ecobee up to run the fan a minimum of ten minutes each hour since that option is available. Since I work during the day and spend a lot of time gone on weekends I didn't notice an issue I was having; however, one evening a couple of weeks ago while watching television there was a rather loud thumping sound in the attic that actually shook the house. It happened three or four times during the evening and I finally realized it was my air handler doing it. The unit had never done this before I switched to the Ecobee3, so I went over all my settings and decided as a first step in troubleshooting to disable the minimum fan run time. The thumping went away and has not returned. The software in the Ecobee evidently has a glitch that allows more than one process to try to control the fan af one time which is causing the fan to stop and restart before it actually is all the way stopped. I am glad I found this out before my fan motor was destroyed. As stated, once I disabled the fan minimum run time the problem went away. I have emailed tech support with the description of the problem and am waiting for them to tell me it is resolved before I go back to using the minimum run time. If this is a big issue for anyone, you might want to wait until it is resolved by Ecobee. It is not a big issue for me and I still like the stat, but be aware that if you use this function you may be putting your fan motor at risk. ... show more
