This or Nest for Apple users? Who can share their experience?
Nest makes it very difficult to precisely AUTOMATICALLY control the device. It's supposed to "learn" what you want, but like most of that sort of AI, it's more maddening than useful.
Ecobee doesn't try to be AI, so it allows you to very precisely say what you want it do. You can use it in two ways.
- If you want to live purely within the Ecobee world, you start by setting up various "Settings" which are things like Home, Away, Sleeping, Exercise, and so on. Each setting is a temperature range and whether or not to force the fan on. (So, eg, I created Exercise as a setting that switches on the fan, and leaves it running even when the temp is in the correct range).
Then you set a time during which to run each Setting, so eg Sleeping from 10pm to 8am, Exercise from 7:30pm to 9pm.
I've found it's not a big deal if the times aren't that accurate, since mostly the temperatures ranges are somewhat similar. So Exercise runs for 90 minutes and somewhere in that time I'll do 30 min of exercise.
The Ecobee uses various sensors to see if a person is present in the house and if not will switch to Away mode.
- Alternatively/In Addition you can connect it to HomeKit and create HomeKit Automations. The main one I use is that when I leave the house it immediately switches to Away (instead of the delayed switchover if it's using its sensors to conclude no-one is around) and when I return it immediately switches back to an appropriate temperature range.
Both Ecobee and Nest come with sensors that detect human presence and temperature. The idea is that if you are in room A which is a few degrees cooler than room B, then the thermostat will try to ensure that room A is in the correct temperature range, regardless of how that affects room B. This can't work miracles, but it is VERY useful if you have the thermostat in say a cold basement, while the rest of the house is much hotter in summer. Ecobee comes with I think one or two sensors built in the pack, for Nest you have to buy a sensor, none comes with the system.
Maybe Nest works well for people who don't understand automation and who constantly keep changing the temp setting on their thermostat? All I can say is that I hate the Nest experience in my friend's houses, whereas the way I have been able to automate Ecobee is DAMN sweet. The house just automatically does what I want it to do, all the time, with no manual involvement after the initial set up. There was a period about two years ago where Ecobee's connection to HomeKit was somewhat dodgy and would fail about once a week, but that seems to have been robustly fixed and I've had no such issues for over a year now.
