temperature not reach setpoint - Thinklight - 21.11.2018

Hy,

Maybe is same example script.
I need script if real temperature difference is more then 1 degree of set point in 24 hours need to send alert.

You need two scripts:
1. Event script mapped to a tag (for both setpoint and current temperature). For each object update, check if delta is within limits or not. If delta is ok, put current timestamp in storage:

Code:
temp =  grp.getvalue('1/1/1')
setp = grp.getvalue('1/1/2')
delta = math.abs(temp - setp)
if delta <= 1 then
  storage.set('last_update', os.time())
  storage.set('notified', false)
end

2. Scheduled script which will check time difference between now and last_update key (in seconds):

Code:
prev = storage.get('last_update', 0)
delta = prev - os.time()
if delta >= (24 * 60 * 60) then
  notified = storage.get('notified')
  if not notified then
    -- send e-mail here
    storage.set('notified', true)
  end
end
