Sonoff SNZB-02P Temperature & Humidity Sensor vs YoLink Smart Wireless Thermometer Hygrometer

The YoLink Smart Wireless Thermometer Hygrometer, which costs slightly less and has a much stronger owner rating, with long-range LoRa connectivity. The Sonoff SNZB-02P Temperature & Humidity Sensor adds low battery alerts.

The YoLink Smart Wireless Thermometer Hygrometer, thanks to its LoRa radio, which covers outbuildings, cellars and distant rooms where a Zigbee sensor would lose contact.

The Sonoff SNZB-02P Temperature & Humidity Sensor, which sends low battery alerts alongside temperature and humidity warnings. The YoLink reports temperature and humidity alerts.

Yes, in practice. The Sonoff SNZB-02P Temperature & Humidity Sensor needs a Zigbee coordinator, and the YoLink Smart Wireless Thermometer Hygrometer needs a YoLink hub to bridge its LoRa network.

The YoLink Smart Wireless Thermometer Hygrometer, because LoRa was designed for exactly that distance. A Zigbee sensor depends on mains-powered repeaters between it and the coordinator.

Buyers with an existing Zigbee network who want cheap sensors across several rooms and value explicit low battery warnings.

Buyers who need readings from far outside normal wireless range, or who simply want the better-rated sensor of the two at a slightly lower price.
