I`m trying to write time and date to a group adress with datatype 19.001. Have been looking in the example: http://openrb.com/example-write-lm2-data...addresses/
but can`t really see there how I`m supposed to Write the actually value to the Group adress. (I`m really new at this)
Can you help me?

Use the code below and modify as needed
Code:
-- get current data as table
now = os.date('*t')
-- system week day starts from sunday, convert it to knx format
wday = now.wday == 1 and 7 or now.wday - 1
-- time table
time = {
day = wday,
hour = now.hour,
minute = now.min,
second = now.sec,
}
-- date table
date = {
day = now.day,
month = now.month,
year = now.year,
}
--- full date bits
OCT08 = now.year - 1900
OCT07 = now.month
OCT06 = now.day
OCT05 = bit.bor(bit.lshift(wday, 5), now.hour)
OCT04 = now.min
OCT03 = now.sec
OCT02 = 0 -- subfields like working day and dst not specified in this sample
OCT01 = 0 -- subfields like quality of clock not specified in this sample
-- write to bus
date_time = string.char(OCT08) .. string.char(OCT07) .. string.char(OCT06) .. string.char(OCT05) .. string.char(OCT04) .. string.char(OCT03) .. string.char(OCT02) .. string.char(OCT01)
grp.write('Date', date, dt.date)
grp.write('Time', time, dt.time)
grp.write('DateTime', date_time)
