CANx dimming

[AnLi_HOUSE]

I would like to dim the light over CAN-UI10 device with 10 one-bit inputs  and IKEA LED strip for dimming.
IKEA has opportunity to dim either with 4 bit or with one byte. Who can help me to develop a script which will do a following: by clicking a button and holding the light will increase brightness for 5% every 0,5 second. And by clicking another button and holding the light will decrease brightness for 5% every 0,5 second. I'm ready to pay for this job.

You can convert 1 bit start/stop to 4 bit up/down/stop via a simple script.

Press (true) = Up, Release (false) = Stop

Code:

value = event.getvalue() and 9 or 0
grp.write('32/1/1', value, dt.bit4)

Press (true) = Down, Release (false) = Stop

Code:

value = event.getvalue() and 1 or 0
grp.write('32/1/2', value, dt.bit4)
