script_time_rainWindCheck.lua

-- script_time_rainWindCheck.lua for Domoticz 
-- Author: CreasolTech https://www.creasol.it

-- This LUA script checks rain and wind data, and controls
-- * outdoor power outlet (in the garden), that can be disabled when raining
-- * mechanical ventilation: activates it only when there is enough wind and not from certain directions (to prevent stove smoke from the neighboor to enter into the house).
-- * if both heat pump and ventilation are active, also activates the hydronic coil inside the ventilation machine (to pre-heat/cool the air)
-- * if WindGuru station id and password are available, export wind/temperature/humidity data to WindGuru website
-- * fan/aspirator in the attic, used for cooling the attic in the Summer, or dehumidifing it, or heat in the Winter
-- * Control the power outlet connected to a mosquitto killer

-- This script needs also to access two configuration files:
--   globalvariables.lua
--   globalfunctions.lua
-- Put this script and the 2 configuration files on DOMOTICZDIR/scripts/lua
