Aeotec Multipurpose Sensor vs YoLink Smart Wireless Thermometer Hygrometer

The YoLink Smart Wireless Thermometer Hygrometer, for temperature and humidity monitoring specifically. It measures both, costs less, is the better reviewed of the two, and sends alerts by app, email and text over a long-range radio. The Aeotec Multipurpose Sensor reads temperature only and is really a door, window and vibration sensor at heart.

Purpose and range. The YoLink is a dedicated temperature and humidity sensor built for long-range coverage of freezers, greenhouses and outbuildings, while the Aeotec is a short-range Zigbee contact and vibration sensor for a door or window that also reports a basic temperature.

No. Despite sitting in the temperature and humidity category, it reports temperature only, alongside its main door, window and vibration detection. Only the YoLink Smart Wireless Thermometer Hygrometer measures humidity in this pair.

Yes, but different ones. The Aeotec Multipurpose Sensor needs a Zigbee hub such as a SmartThings or Home Assistant coordinator. The YoLink Smart Wireless Thermometer Hygrometer needs its own YoLink hub to bridge its long-range radio to the app.

SmartThings and Home Assistant users who want one Zigbee device to cover a door or window, catch a knock through vibration detection, and read a rough ambient temperature, rather than someone shopping specifically for humidity monitoring.

Anyone watching a freezer, a greenhouse, a coop or a detached building who needs both temperature and humidity, wants alerts with no subscription, and needs a radio that reaches farther than Wi-Fi or Zigbee typically can.
