Looks great :)

Thanks..,
Jesse asked me to validate resolution only for RG15 - I have done this the same way as was done with disable led only for applying to rg9, I did a quick try in my yaml and it seems ok but the test3.yaml failed.
Would you have time to have a Quick Look at the sensor.py - I only added one line

[functionpointer]

test3.yaml should also contain resolution: low for the RG_15 instance. This would add a test for the newly added option.
