Delay for DALI !

[davidchispas]

DALI bus is slow so you should minimize the number of requests. If you want to update two objects at once better do it like this:

Code:

function queryactual(short, addr1, addr2)
  local res, err = dalicmd('internal', 'queryactual', { addrtype = 'short', address = short })
  if res then
    local val = res:byte()
    if val > 0 then
      val = math.floor(val / 2.54 + 0.5)
      val = math.max(1, val)
    end
    grp.checkupdate(addr1, val)
    grp.checkupdate(addr2, val)
  end
end

queryactual(0, '1/1/0', '1/2/0')

You should also add at least one second delay between queries otherwise you will overload the DALI bus.

Thanks Admin, what is more advisable not to saturate the dali bus? make a query script for each group of ballasts, or make a single script for all ballasts?

I understand that if 10 scripts are executed every 3-5 seconds at a time it is worse, right?
