The Aqara Temperature and Humidity Sensor is open: it runs on Zigbee and works with Home Assistant directly or reaches the big ecosystems through an Aqara hub. The Ecobee SmartSensor is closed: it speaks a proprietary radio to ecobee thermostats only, so it is only useful inside an ecobee home.
The Aqara Temperature and Humidity Sensor reads temperature, humidity and atmospheric pressure. The Ecobee SmartSensor reads temperature and adds occupancy detection, which is what lets it prioritize an occupied room, but it does not measure humidity or pressure.
The Ecobee SmartSensor runs for around five years on a single CR2477 coin cell, while the Aqara Temperature and Humidity Sensor is rated for about two years on a CR2032. Over the life of a sensor you mount and forget, that is fewer swaps and fewer chances to crack a battery cover.
The Ecobee SmartSensor carries a three-year warranty against one year for the Aqara Temperature and Humidity Sensor. It is the longer commitment of the two, though it only pays off within an ecobee setup.
The Aqara Temperature and Humidity Sensor supports both temperature and humidity alerts, so it can warn on a damp room or a cold fridge. The Ecobee SmartSensor alerts on temperature only, since humidity is not one of its readings.
The Aqara Temperature and Humidity Sensor pairs with an Aqara hub or a third-party coordinator and is not tied to a single thermostat brand.
The Ecobee SmartSensor feeds that thermostat directly over its proprietary radio and is the cheapest way to add room-priority comfort to it.
The Ecobee SmartSensor tracks temperature and occupancy only, while the Aqara Temperature and Humidity Sensor adds humidity and atmospheric pressure.
Occupancy detection on the Ecobee SmartSensor lets an ecobee thermostat favor the rooms people are actually using.
The Ecobee SmartSensor is rated for around five years on one coin cell, against roughly two years for the Aqara Temperature and Humidity Sensor.
The two reviews start from the same comfort goal and split on scope. Aqara Temperature and Humidity Sensor owners love the accuracy, the tiny size that tucks into fridges and covered outdoor corners, and the freedom to pair it with almost any Zigbee hub, and they grumble mainly about a brittle battery cover and occasional short battery life. Ecobee SmartSensor owners describe a thermostat upgrade, saying it finally makes an ecobee system react to the room people are in and stops conditioning empty ones, with pairing in minutes and years of battery life; their gripes are a spotty link in large multi-story homes, a first-try pairing that sometimes fails, and a price they find high for a small puck.
For a general smart home the Aqara Temperature and Humidity Sensor is the more flexible pick, with temperature, humidity and pressure readings and open Zigbee support, plus alerting on both. The Ecobee SmartSensor wins inside an ecobee home, where occupancy detection and a much longer battery make it a strong thermostat companion.
The Aqara Temperature and Humidity Sensor is a standalone Zigbee sensor with three readings and broad hub support. The Ecobee SmartSensor is a thermostat accessory with no radio of its own beyond a proprietary link, reading temperature and occupancy only, so the Aqara fits any home and the Ecobee only fits an ecobee one.
No. The Aqara Temperature and Humidity Sensor measures temperature, humidity and atmospheric pressure. The Ecobee SmartSensor measures temperature and detects occupancy, but it does not report humidity or pressure.
The Ecobee SmartSensor reaches Home Assistant through the ecobee thermostat and its integration, not directly. The Aqara Temperature and Humidity Sensor connects to Home Assistant directly through a Zigbee coordinator.
Anyone who wants a small, accurate sensor for temperature, humidity and pressure across a Zigbee or Home Assistant home, with alerts and automations and no dependence on one thermostat brand.
Existing ecobee thermostat owners who want room-level control and occupancy detection so the system heats and cools where people are, and who value a battery that lasts for years.
