Apollo MSR-2 vs Moes Human Presence Detector (Ceiling Mount)

Full Smart Presence Sensors comparison in 2026

Data from Amazon and official Apollo Automation and Moes sites.
2026 verdict
A hobbyist board versus a plug-and-play ceiling sensor: the Moes Human Presence Detector (Ceiling Mount) wins this presence sensor pairing on connectivity and integrations, reaching Google Home and Alexa out of the box while offering both Wi-Fi and Zigbee-hub connection paths and the longer detection range of the two. The Apollo MSR-2 counters with a lower price and open, DIY-friendly hardware built around Home Assistant, but it stops there, with no Alexa, Google Home, Apple HomeKit, SmartThings or IFTTT support listed at all. Both are wired, pair a presence sensor with a light sensor, and skip multi-person tracking, fall alerts and weather resistance. Home Assistant tinkerers who never touch a voice assistant can save money with the Apollo; anyone wanting Alexa or Google Home working immediately should mount the Moes instead.
