Delay for DALI !

[admin]

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.
