Everything Presence One Downlight Enclosure

–- UPDATE --

This design has some issues with the spring geometry. The unit is not held in the ceiling with enough force, and mine have started to drop a little. Not awesome!

There's a redesign on the way that will accommodate all revisions of the sensor and utilises a new fixing mechanism that's significantly more solid.

My downlight enclosure for the Everything Presence One sensor! Watch the video for more!

• Repackages the Everything Presence One as a ceiling-mounted sensor
• Includes mounting for a POE power adapter
• Fits a 90mm or 92mm downlight hole

Parts
 

• Everything Presence One Sensor
• Anvision POE adapter
• Downlight springs (anything up to 18mm wide should work)
• 6 x M3x12mm
• 1 x M3x6mm
• 2 x M3x25mm
• Female dupont connector wires (I just cut the F to F wires in half for 10cm in length)

Printing

Print each component flat side down, I used a textured print bed. Matte filaments blended into my ceiling best.

Some support required for the Back_Cover component. Tree supports worked well for me! 

In the video, I used Bambulab Matte Ivory White (11100)

Assembly

Disassemble the EP1 sensor and POE module. Solder your new wires to the +5v and G pins on the POE PCB. Mount the POE PCB on the POE_Mount print with an M3x6 screw.

Remove the MMwave and PIR sensor from the EP1. Attach the EP1 to the PCB_Mount component in the labelled position using 2 M3x12 screws. Pass the wires through the hole in the PCB_Mount and connect them to the 5V headers. Now you can reattach your sensors.

The M3 screws pass through the PCB_Mount and into the POE_Mount, sandwiching the POE_Mount in place. 
 

The PCB_Mount is then sandwiched between the Face_Plate and Back_Cover which are held in place with 4 x M3x12 screws.
 

Lastly, install your downlight springs, ensuring the ‘tail’ of the spring is inserted into the retaining hole in the Back_Cover, and holding it in place with an M3x25mm screw through the spring's coil.

You're done!
