Data from the official Apollo Automation and Sonoff sites.
2026 verdict
Zigbee behind a hub still out-earns solo Wi-Fi in this budget presence sensor duel: the SONOFF Zigbee Human Presence Sensor wins on price and integrations, adding Google Home, Alexa, SmartThings and IFTTT that the Home Assistant-only Apollo MSR-2 skips entirely. The Apollo MSR-2 holds its ground with a direct Wi-Fi connection and no hub requirement at all, built around an LD2410 radar module, though it carries no public rating yet and no store listing beyond the manufacturer's own site. Both are wired, include a light sensor, and leave out multi-person and fall detection. DIY Home Assistant builders can still pick the Apollo MSR-2; everyone wanting broader platform support should pick the SONOFF.

Frequently Asked Questions
Which is better overall: Apollo MSR-2 or SONOFF Zigbee Human Presence Sensor?
SONOFF Zigbee Human Presence Sensor wins on price and platform reach, adding Google Home, Alexa, SmartThings and IFTTT. Apollo MSR-2 counters with a hub-free direct Wi-Fi connection, but stays limited to Home Assistant only.
What is the biggest difference between Apollo MSR-2 and SONOFF Zigbee Human Presence Sensor?
The network path. The SONOFF is a Zigbee device that needs a Zigbee hub, but in exchange reaches five platforms. The Apollo MSR-2 joins Wi-Fi directly with no hub at all, but was built for Home Assistant only.
Where can you buy each sensor?
The SONOFF Zigbee Human Presence Sensor has an established owner rating. The Apollo MSR-2 is sold directly from Apollo Automation's own site, so it has no public rating history yet.
Do both include a light sensor?
Yes, both the Apollo MSR-2 and the SONOFF Zigbee Human Presence Sensor pair presence detection with a light sensor, though the SONOFF's reports only coarse dark, medium and light levels.
Who should buy Apollo MSR-2?
Choose Apollo MSR-2 if you run Home Assistant exclusively and prefer a direct Wi-Fi connection over adding a Zigbee hub, built around the LD2410 radar module.
Who should buy SONOFF Zigbee Human Presence Sensor?
Choose SONOFF Zigbee Human Presence Sensor if you already run a Zigbee network and want the cheaper option with broader platform support, including SmartThings and IFTTT.
