Light scenes KNX

[khalil]

This example will dim 3 lights from 0% to 100% in 10% steps with 0.2 seconds delay between each step. You can adjust the step/delay as needed and also add new group addresses to the list.

Code:

step = 10 delay = 0.2 addrs = { '32/1/15', '32/1/16', '32/1/17' } for _, addr in ipairs(addrs) do   obj = grp.find(addr)   for value = 0, 100, step do     obj:write(value)     os.sleep(delay)   end end

excuse me admin dor this question, it's for learning.
why do you use grp.find.
could we use grp.write(add,value) instead
