Project Smart home - Anemometer + Humidity + Light intensity
In order to get information from outside of the house - to be able control house equipment (as electric sunblinds on windows) according weather conditions - I cretated a this Weather station.
Weather station collect a data about wind speed, intensity of light, humidity and temperature.
Data are sent in realtime to Homeassistant where I can trigger various scenarios.
Too high speed of wind? -> roll-up blinds to covers.
High intensity of light? -> roll blinds down to shield inside
(can be varied with actual time, and roll down covers only on one side of House - e.g. west side of house on afternnoon)
