Thermostat with auto disable function

[RomansP]

Here is a script, but please carefully test it and give the feedback.
I will make a changes if necessary.
It is a resident script, with sleep time 60 seconds.

Code:

if not motion_minute_counter then
  motion_minute_counter = 0
end

if not temp_minute_counter then
  temp_minute_counter = 0
end

motion_detected = grp.getvalue('motion_detected') -- boolean
current_temp = grp.getvalue('current_temp') -- float
window_opened = grp.getvalue('window_opened') -- boolean
heater_status = grp.getvalue('heater_status') -- boolean

--log(motion_detected)
--log(current_temp)
--log(window_opened)
--log(heater_status)

set_temperature = 25 -- Celsius degree
hysteresis = 1 -- Celsius degree

one_hour = 60 -- minutes

if not motion_detected then
  motion_minute_counter = motion_minute_counter + 1
else
  motion_minute_counter = 0 -- motion was detected unset counter
end

if current_temp > set_temperature then
  temp_minute_counter = temp_minute_counter + 1
else
  temp_minute_counter = 0
end

if current_temp < set_temperature and
      not window_opened and
      motion_minute_counter < one_hour and
      not heater_status then -- heater is off
 
  grp.write('heater_control', true)
 
end


if (current_temp + hysteresis > set_temperature or window_opened) and heater_status then
  grp.write('heater_control', false)
end
 
if (motion_minute_counter > one_hour or temp_minute_counter > one_hour) and heater_status then
  grp.write('heater_control', false)
end

--log(motion_minute_counter)
--log(temp_minute_counter)
