Simple motion sensor

Hi all,

One of the things that were missing for my needs on Shelly products were the multiple click button and a simple motion sensor.

The multiple click button is now here, but for the motion sensor, Shelly just have "Sense", that is too good and expensive for some simple scenes of motion.

Until Shelly launch it's own motion sensor, do you know if there are some in the market that can work with shelly devices?

Thank you.
