For me on Homey KAKU app v7.6.0 works perfectly OK with a ACC-250 .
DIMLEVELS are between 0 and 1 so setting it to 25% returns 0.25 and calculating with that in a logic card to + 0.02 and setting that as a new Dimlevel set it to 0.27.
No issues here on Homey Pro running the latest firmware ( v 13.4.1-rc.1 shouldn’t be differentfrom the latest beta)
