Hello,
ich bought the grove gesture sensor and connected it without the grove base hat directly to the raspberry pi gpio pins according to this https://github.com/eouia/MMM-GroveGestures. My problem is, that the raspberry pi does not even detect an i2c connection. I enabled i2c in the rapsberry pi config. With the help if i2c tools I check for the correct connection but the matrix tells me that nothing is connected.

I have no clue what the problem might be. Is it maybe necessary to use the grove base hat? Maybe the sensor is broken? Is there a way to check this?
Everything like processing code which uses the sensor does not work, of course.
Kind regards,
Thomas
