Frequently Asked Questions
Which is better overall: Aeotec Multipurpose Sensor or Sonoff DW2-WIFI?
The Sonoff DW2-WIFI wins overall as the more affordable option with broader connectivity, connecting directly over Wi-Fi with no hub and adding IFTTT, low-battery alerts and 90-day history. The Aeotec Multipurpose Sensor counters with a higher owner rating and added temperature and vibration sensing.
What is the biggest difference between the Sonoff and Aeotec sensors?
How they connect. The Sonoff DW2-WIFI is a hub-free 2.4GHz Wi-Fi sensor, while the Aeotec Multipurpose Sensor is a Zigbee device that needs a Zigbee hub. The Aeotec, in return, adds temperature and vibration sensing the contact-only Sonoff lacks.
Does either sensor work without a hub?
The Sonoff DW2-WIFI does. It connects straight to 2.4GHz Wi-Fi via the eWeLink app with no separate hub or bridge, though owners note pairing can be finicky and may need the Wi-Fi 'b' protocol enabled. The Aeotec Multipurpose Sensor always requires a Zigbee hub.
Who should buy the Aeotec Multipurpose Sensor?
Buy the Aeotec Multipurpose Sensor if you run a Zigbee hub and want a higher-rated sensor that also reads temperature and detects vibration for automations. It suits SmartThings, Hubitat and Home Assistant households wanting a versatile multi-sensor.
Who should buy the Sonoff DW2-WIFI?
Buy the Sonoff DW2-WIFI if you want a cheap, hub-free Wi-Fi sensor for mailbox or garage-door alerts, use eWeLink or Home Assistant, and are comfortable troubleshooting a fiddly pairing process. It offers low-battery alerts and 90-day history at a low price.
