array of group addresses - almoisey - 18.07.2024

Hello. I have a task to write an array of identical values to a large number of group addresses (~200) ( like grp.write('1/*/*', value)). How can this be done using array commands?
Thanks

Assign a common tag to the required objects then use this script:

Code:
value = 1

objects = grp.tag('my_tag_name')

for _, obj in ipairs(objects) do

  res = obj:checkwrite(value)

  if res then

    os.sleep(0.1)

  end

end

A better approach is to assign a common group address to all KNX devices because sending many telegrams at once can overflow the bus. The script above has a delay between each telegram to prevent this but it means that some devices will receive the value later.
