What the differences mean

Heat pause or motion

The Ecobee SmartSensor for Doors & Windows can pause HVAC on an open door and lists occupancy. It does not list a motion sensor, and it does not measure temperature. The SwitchBot Contact Sensor lists motion and light as well as contact, and it has no HVAC link. A hallway that should turn on a lamp is a SwitchBot job. A door that should stop the furnace is an Ecobee job.

Warranty

The Ecobee SmartSensor for Doors & Windows carries a 3 year warranty. The SwitchBot Contact Sensor carries 1 year. That is the Ecobee's scored edge. Battery ratings are similar on paper, 3 years on a CR2477 against 3 years on two AAA cells, so warranty is the gap, not the cell life.

Platforms

Home Assistant is supported on the SwitchBot Contact Sensor and not on the Ecobee SmartSensor for Doors & Windows. Alexa, Google Home, SmartThings, Apple Home and Matter need a SwitchBot hub. The Ecobee reaches Google Home, Alexa and Apple Home only through the thermostat, and it does not support SmartThings or Matter.

History

Both keep a history. The Ecobee sheet says history is supported, without a day count. The SwitchBot sheet says the same. The Sonoff-style 90 day figure is not on either product here, so history does not separate them.

Which one to buy if

What owners say

Owners of the SwitchBot Contact Sensor praise speed and a small install, and they care about motion and light as much as the contact itself, while warning that the good remote and voice features assume a SwitchBot hub. Owners of the Ecobee SmartSensor for Doors & Windows praise a tighter job: the thermostat reacts when the door opens, the hardware is discreet, and notices are reliable. They are much louder about the subscription wall and about expecting temperature sensing that this model does not have.

Frequently Asked Questions

Which is the better hallway sensor, the Ecobee SmartSensor for Doors & Windows or the SwitchBot Contact Sensor?

The SwitchBot Contact Sensor. It is the more affordable and better reviewed, with contact, motion and light, Home Assistant direct, and the other platforms through a SwitchBot hub. The Ecobee SmartSensor for Doors & Windows is the one that pauses HVAC and carries the 3 year warranty.

Are these affordable door sensors for a normal home?

The SwitchBot Contact Sensor is the more affordable of the two and does not need an ecobee thermostat. It still needs a SwitchBot hub for remote voice control. The Ecobee SmartSensor for Doors & Windows costs its place in an ecobee system, where an open door can pause the heat, and motion alerts need a subscription.

Does the Ecobee sensor measure temperature like a room sensor?

No. Temperature is not supported on the Ecobee SmartSensor for Doors & Windows. Occupancy is. The SwitchBot Contact Sensor does not measure temperature either. It measures motion and light instead.

Which warranty is longer?

The Ecobee SmartSensor for Doors & Windows, at 3 years, against 1 year on the SwitchBot Contact Sensor. Published battery life is 3 years on both, a CR2477 on the Ecobee and two AAA cells on the SwitchBot.

Who should buy the Ecobee SmartSensor for Doors & Windows?

An ecobee thermostat owner who wants the hallway door to pause heating or cooling, plus occupancy, and who accepts the subscription for motion alerts. Buy the SwitchBot Contact Sensor for motion, light and Home Assistant.
