Code:

-- setpoint object
obj = '1/1/1'
-- storage key, unique for each object
key = 'lastupdate_' .. obj
-- current timestamp
now = os.time()
-- timestamp of last update
upd = storage.get(key, 0)

-- time is in seconds (30 minutes)
if (now - upd) >= 30 * 60 then
  -- set new last update time
  storage.set(key, now)
  -- increase setpoint by 0.5
  setpoint = grp.getvalue(obj)
  grp.write(obj, setpoint + 0.5)
end
