Apollo MSR-2 vs SwitchBot Presence Sensor comparison

Updated May 2026

Data from Amazon and official Apollo Automation and SwitchBot sites.

2026 verdict

Two radar-based presence sensors, but only one is built for the mainstream smart home: the SwitchBot Presence Sensor wins this presence sensor pairing on price and integrations, running wire-free on batteries and reaching Alexa, Google Home, Apple HomeKit and SmartThings through its hub. The Apollo MSR-2 counters with a narrower pitch, a wired sensor built around an LD2410 radar module that connects to Home Assistant only, sold directly from Apollo Automation with no other platform support and no public rating history yet. Both include a light sensor and skip multi-person tracking and fall alerts. Buyers wanting broad out-of-the-box compatibility should choose the SwitchBot; Home Assistant-only builders wanting a direct-connect radar sensor should choose the Apollo MSR-2.

Frequently Asked Questions

Which is better overall: Apollo MSR-2 or SwitchBot Presence Sensor?

SwitchBot Presence Sensor wins on reach: a lower price and integrations with Alexa, Google Home, Apple HomeKit and SmartThings through a SwitchBot Hub. Apollo MSR-2 is the narrower device, wired and Home Assistant-only, without the SwitchBot's platform breadth.

What is the biggest difference between Apollo MSR-2 and SwitchBot Presence Sensor?

Platform support and power. The SwitchBot is battery powered, wireless over Bluetooth, and unlocks Alexa, Google Home, HomeKit and SmartThings through a SwitchBot Hub. The Apollo MSR-2 is wired over USB-C and Wi-Fi, and connects to Home Assistant only, with no hub or bridge needed for that single platform.

Does the Apollo MSR-2 have a store rating like the SwitchBot?

No. The Apollo MSR-2 is sold directly from Apollo Automation rather than through a major retailer, so it carries no public star rating yet. The SwitchBot Presence Sensor is sold through Amazon with an established review history.

Do both include a light sensor?

Yes. Both the Apollo MSR-2 and the SwitchBot Presence Sensor pair their radar-based presence detection with a built-in light sensor, and neither supports multi-person detection or fall alerts.

Who should buy Apollo MSR-2?

Choose Apollo MSR-2 if you run Home Assistant exclusively and want a wired, direct Wi-Fi radar sensor built around the LD2410 module, without needing Alexa, Google Home, HomeKit or SmartThings support.

Who should buy SwitchBot Presence Sensor?

Choose SwitchBot Presence Sensor if you want cable-free placement, a lower price, and the widest platform reach of the pair through a SwitchBot Hub.
