Aqara Motion Sensor P1 vs Arlo All-in-One Sensor

Which sensor covers more ground, literally and figuratively? The Aqara Motion Sensor P1 does, edging out the Arlo All-in-One Sensor overall on owner rating, integrations, alerts and detection range. Aqara's built-in light sensor and configurable timeout reach Apple HomeKit, Alexa, Google Home, Home Assistant and IFTTT (an Aqara Hub is only required for Alexa or Google Home, not for generic Zigbee use), a wider net than the Arlo All-in-One Sensor manages with just Google Home and Alexa. The Arlo All-in-One Sensor answers with a lower price and a broader sensor package, adding a temperature reading that the Aqara Motion Sensor P1 lacks alongside its own motion and light sensors, though Arlo has no standalone radio at all, Wi-Fi, Bluetooth, Zigbee, Z-Wave and Thread are all absent, and it depends entirely on a compatible Arlo Security System hub or keypad, unlike the Aqara Motion Sensor P1, which pairs directly with a generic Zigbee coordinator. Buyers who want fast, Zigbee-native triggering with the widest ecosystem reach should choose the Aqara Motion Sensor P1; those who want one inexpensive sensor tracking motion, light and temperature inside an existing Arlo household should pick the Arlo All-in-One Sensor instead.
