@TheoL Please see attached stripped version of @pjjarzembowski code. I see that interrupt is being detected, but dimmer portion does not work yet.
/****************************************************************
Title: MySensors enabled, gesture controlled lamp.
This lamp can be turned on/off, and dimmed by gestures. And it can be controlled by any Home Automation
system, that can talk with MySensors.
Supported gesture:
1. Left to right stroke: turns lamp on
2. Right to left stroke: turns lamp off
3. Down to up stroke: increases brightness (When brightness is already at max, the lamp will blink - duration and blink count can be changed in the sketch)
4. Up to down stroke: decreases brgihtness (When brightness level is at 0 the lamp is off)
The gesture sensor used in this Sketch is an APDS-9960 RGB and Gesture Sensor, sold by SparkFun. They can be found on eBay and Aliexpress as well.
See Sparkfuns hookup guide for pin lay-out ( https://learn.sparkfun.com/tutorials/apds-9960-rgb-and-gesture-sensor-hookup-guide )
IMPORTANT: The APDS-9960 can only accept 3.3V! Use bi direction level converter when using another Arduino than a Pro Mini 3.3V
This Sketch is based upon the GestureTest exampl developped by,
Shawn Hymel @ SparkFun Electronics on May 30, 2014. See https://github.com/sparkfun/APDS-9960_RGB_and_Gesture_Sensor
The lamp itself is a white LED strip, controlled by an N channel MOSFET.

Revision history:
3-07-2017 Version 2 by pjjarzembowski
- Changed for tests on Mysensors 2.0
20-03-2016 Version 1.1 by Theo:
- set the brightness level to defined BRIGHTNESS_INCREMENT, when lamp is being turned on be a gesture and the current brightness level is 0.
This was a little bug in previous version. It sometimes seemed that the APDS didn't work, but in some cases I had to increase brightness after
I turned the lamp on.
- cleaned up the code a bit
19-03-2016 Version 1.0 by Theo
- Developed and test with MySensors release 1.5.4
