With built-in Alexa Voice Service, ecobee4 can listen to your voice commands and respond. Have it set a timer, read you the news, adjust the temperature, and more. It also comes with a room sensor that helps manage hot and cold spots in your home, delivering comfort in the rooms that matter. And because they can detect occupancy, they can automatically enable the right mode on your ecobee4 for energy savings when it senses no one is home.
Q: does the ecobee4 use z wave technology
A: No, the ecobee4 thermostat only uses WiFi for connectivity. My Smartthings hub has a built-in device handler for ecobee which uses the cloud API to read data and send commands to the thermostat.
A: You don't need the DOT because the thermostat has full Alexa functionality. HOWEVER, the microphone and the speaker on the thermostat sucks when compared with the DOT.
Q: Does the thermostat work without WiFi or Is WiFi always required?
A: Thermostat works without WiFi, it will be in a manual mode that means Alexa does not work and the smart phone app does not work.
A: Since you referenced opening and closing ducts.... I will also put in my comments here, I have answered this same way on several other questions and it might also help you here; The Ecobee in and of itself can help you with what zone you care about for temperature but won’t help you with being able to truly ‘zone’ the house. You can set what sensor(s) you care about in the comfort setting group, from 1 to as many sensors as you have. During the sleep group, I have it only caring about the remote sensor I have in the bedroom. I actually wanted to zone my house because my bedroom would freeze out during the day while the AC was trying to keep the living room temperature comfortable and then at night, we would overheat because now the living room was fine but the bedroom got hit with the sun during the evening. The Ecobee can with the extra sensors make the furnace care about the other rooms and or average out the house, or at night focus on a smaller number of sensors or even a specific one like I talked about, my bedroom. I myself wanted more though and have areas that I don’t care about turn off the vents when I don’t care about them or when they reached temperature that would freeze out stop after the room temperature leveled off at the desired point. I went with the Ecobee and Keen Home smart vents https://keenhome.io because they actually tie together and work together to get ‘zone’ effects like I wanted. The smart vents can close off when the room reaches the desired level for that specific room and then open back up when needed. It doesn’t “call for heat” or “call for cool” but if you use an Ecobee sensor in that room, the Ecobee can then call for heat/cold based on average for the house or for that specific room and then the smart vents will use that same sensor to detect and close off the vent when the set level for that room is reached. It is the best way I have found to do this kind of zoning without having my whole system replaced with something more expensive. I hope that helps.
A: In short, yes. I have the ecobee4 and it works perfect. I needed to make some minor adjustments after I'd installed it the next day. However, I was at work when my wife complained about it. I opened the app and made the requested adjustment and it's worked perfectly since. I liked it so much that when another thermostat went out 10 days later I didn't think for a minute. I jumped out and picked up another one.
Q: Does the Ecobee4 come in white??
A: Unfortunately no, which is why I have not yet purchased Ecobee even though it is compatible with CoolAutomation. Nest was smart enough to come out with white. I don't know why Ecobee does not recognize the obvious. Most people do not want to mount black squares on their white walls.
A: No, it would only turn on the 1 (Main House) Furance. Put 1 sensor in the ‘other’ heat pump Furance room, and IF it’s getting colder there, compared to the Main House, the Main Furance would kick on!
