The SONOFF CMSH03 is the ideal solution for smart home enthusiasts looking to integrate their motion and presence sensors into a ceiling for a minimalist, professional look. It is specifically designed to provide a secure, flush-mount installation for the SNZB-03P and SNZB-03PR2 models without obstructing sensor coverage or functionality. While this adapter offers a clean aesthetic upgrade, users should ensure their ceiling material can accommodate the spring-clip mounting mechanism and that they have sufficient overhead space for the housing.

You will need a hole saw or cutting tool to prepare the ceiling opening, but no tools are required for the actual mounting of the adapter.
Ensure you have at least 5cm of clearance behind your ceiling to accommodate the sensor and the adapter housing.
Ensure the spring clips are fully extended and gripping the back of the drywall material.
Check that the adapter is installed in a location away from HVAC vents or fans that might trigger the infrared sensor.
Gently pull the edges of the adapter downward; the spring clips will retract to allow the unit to slide out from the ceiling cavity.
To install, first verify that you have clear space behind the ceiling drywall to accommodate the housing of the adapter. Use the provided template (if applicable) to cut a circular hole, insert the adapter with the sensor attached, and release the spring clips so they snap against the backside of the ceiling.
Compatibility: This unit is strictly for the SONOFF SNZB-03P and SNZB-03PR2.
Care: Keep the sensor lens clean from dust. To change the battery, simply pull down on the unit to release the spring clips, remove the sensor from the adapter, perform the battery change, and push the adapter back into the ceiling opening.
