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
