Ecobee is likely the second largest smart thermostat maker after Nest. Their special sauce is every thermostat also has a remote temperature and motion sensor and you can add more, to make a sensor network to optimize power use in your HVAC. They also make other Smarthome products.

Which is why I went with Ecobee. As with many home, the thermostats are located in teh hallway, which is probably the worst in terms of controlling temperature for occupied spaces. Ecobee’s design senses what rooms are occupied and adjusts the HVAC system’s output accordingly; which is how HVAC systems should have been designed anyway.
I think the A/C should be turned up to keep the bodies cool. Or is that just how I use hotel rooms? (It's a fucking joke, alright! Funny how I feel the need to point it out these days.)
I hope it can sense people who are asleep and not moving. I once stayed at a "green" hotel. Every few hours I had to sit up in bed and wave my arms to keep the A/C running. My "green" office light can't detect me working at my desk. If I want to keep the lights on I have to pick up my trash can and wave it around. I disabled the ceiling lights and use a floor lamp on dark days. I'm probably saving power, since I rarely turn it on.
From looking at my data it appears to register room occupied periodically while asleep; I’m guessing the normal sleep movements will trigger it as it isn’t always showing “occupied” but does so at periodic intervals.
Years ago I worked in an office with “smart” switches and would have to wave my arms periodically to keep the light on. My office had a glass wall so if someone was walking by and saw me waving they’d stop in

I never understood what people expect to gain with this considering there is only a binary choice of the thing being on or off or high/low if you are lucky. There is no way to heat or cool individual rooms with most forced air HVAC systems.
Temperature averaging at multiple locations is helpful to avoid oscillations yet beyond that system design to account for losses and airflow is what matters not how fancy the controls are. People are more sensitive to change in temperatures rather than absolute temperat
The difference between the temperatures can be used to keep the circulation fan on until the difference is reduced to some specified level. Or, so the minimum/maximum temperature can be the setpoint for heat/AC, for instance.

People are more sensitive to change in temperatures rather than absolute temperature. Keeping a uniform temp throughout the structure and throughout time even at a lower setpoint is better than screwing with controls that can't accomplish jack to begin with.

The problem with this is it fails to address the underlying issue. It does not address the temperature differences.
When someone leaves the occupied room with the doors closed they feel hot.
When someone enters the occupied room even at the desired temperature they feel cold.
People are uncomfortable as they move about the building.
Issues with doors closed is sometimes missing or improperly sized returns.

The problem with this is it fails to address the underlying issue. It does not address the temperature differences.
Which is irrelevant in my situation. As long as the occupied room is comfortable the relative temperature differences are of no concern.

People are far more sensitive to changes in temperature than absolute temperature. Failure to prioritize uniform temperatures leads to an uncomfortable building regardless of what the set point happens to be or how fancy the control loop of the on/off switch.
That depends on how the building is used. Not every building has people constantly moving from area to area; hence such a setup fits their needs at a cost a lot less than redoing HVAC systems.
There is no way to heat or cool individual rooms with most forced-air HVAC systems.
"Smart" heater registers are available. They have booster fans to deliver heated/cooled air to individual rooms.
They can be built-in, or you can easily add them to an existing system. Just unscrew the old register from the floor/wall and screw on the replacement.

Smart is properly sizing supply and returns to provide uniform coverage throughout the structure. Stupid is cutting corners by applying band aids.
Attempts to block and or force air thru HVAC system is a bad idea. Forced air heating systems are calibrated by installer and designed to operate within a specific static pressure range. Fucking around without doing appropriate TR and SP measurements will damage the equipment. Too little static pressure increases HX wet time leading to premature failure. Too

That would add a fair amount of complexity (and cost). Used to work at a small business where our location was in a small office building with one furnace. Each unit did have their own thermostat and could control their own heating and cooling but it was controlled by a (complex) damper system. Physically it wasn't that complex, but the control/electronic side of it was.
