Controlling Temp with timer

[admin]

Create an event script mapped to temperature object:

Code:

temp = event.getvalue()

curr = temp > 22
prev = storage.get('temp_over')

if curr ~= prev then
  if curr then
    storage.set('temp_time', os.time())
    storage.set('temp_notified', false)
  end

  storage.set('temp_over', curr)
end

Then create a scheduled script that runs every minute to check whether e-mail needs to be sent. Change delta time if needed (60 * 60 = 1 hour in seconds).

Code:

curr = storage.get('temp_over')
notified = storage.get('temp_notified')
if curr and not notified then
  now = os.time()
  time = storage.get('temp_time', now)

  delta = now - time
  if delta > 60 * 60 then
    -- send email
    storage.set('temp_notified', true)
  end
end
