Turn off light in 4 hours

[edgars]

Another timer example.

Task: If there is 0 sent to grp address AND it stays for 30 min at this value, switch on relay for 3 min. This is used in sauna installation to drain water after sauning is finished.

Event script, input is binary object:

Code:

value = event.getvalue()

-- turn off timer and turn relay off
if value then
 storage.delete('timer')
 grp.write('1/1/1', false)
-- start timer if not already started
else
 timer = storage.get('timer')
 if not timer then
   storage.set('timer', 0)
 end
end

Scheduled script - run every minute:

Code:

-- check if timer is running
timer = storage.get('timer')
if timer then
 timer = timer + 1
 timer.set('timer', timer)

 -- turn relay on after 30 minutes
 if timer == 30 then
   grp.write('1/1/1', true)
 -- turn relay off after 33 minutes  
 elseif timer == 33 then
   grp.write('1/1/1', false)
 end
end
