Alarm missing grp update

[admin]

Scripts looks ok. How is it set up, as a scheduled script which runs every minute?

It can be written a bit shorter like this, logs might help you to find out why it's not working.

Code:

heartbeat_time = 60 -- Minutes
heartbeat_device_object = '32/1/1' -- Change address to your heartbeat device
heartbeat_alarm_object = '32/1/2' -- Change address to a alarm address

obj = grp.find(heartbeat_device_object)

if obj then
  delta = os.time() - obj.updatetime
  alarm = delta >= heartbeat_time * 60
  log(delta, alarm)
  grp.checkwrite(heartbeat_alarm_object, alarm)
end
