Aeotec Multipurpose Sensor vs Shelly BLU H&T ZB

For climate monitoring, the Shelly BLU H&T ZB, which reads temperature and humidity and lasts about three years on a coin cell. The Aeotec Multipurpose Sensor is the better device when the job is a door, a window or a vibration alert, with a temperature reading on the side and no humidity at all.

Contact sensing versus humidity sensing. The Aeotec Multipurpose Sensor detects open and close, vibration and tilt and reads temperature only, while the Shelly BLU H&T ZB measures temperature and humidity with no contact sensing.

No. The Aeotec Multipurpose Sensor measures temperature alongside its door and window contact, vibration and tilt sensing, and it has no humidity sensor. The Shelly BLU H&T ZB is the one of these two that reads humidity.

No. The Shelly BLU H&T ZB is a temperature and humidity sensor with no contact or vibration sensing. For open, close or knock detection, the Aeotec Multipurpose Sensor is the device built for it.

The Shelly BLU H&T ZB, rated for about three years on a CR2032, against about a year on a CR2450 for the Aeotec Multipurpose Sensor.

No. The Shelly BLU H&T ZB has no display, only a button and one red LED. Its readings are delivered over Bluetooth or Zigbee, and the Aeotec Multipurpose Sensor does not have a screen either.
