Objectives

• Order 4 solenoid valves (3 watering zones + 1 pool filling)
• Detect water shortage through a float in the water tank
• Check temperature and humidity (especially outside humidity to see if it rained)

Rules Set 2 (Links GPIO0=Bouton button to GPIO12=Jus relay)

on Button#Button do if [Jus#Juice]=1 GPIO,12,0 // Off else GPIO,12,1 // Endive endon lighter

Rules Set 3 (Links GPIO5 water level sensor to blue LED)

Note: : At this stage, the lack of water is not taken into account because of a physical concern of the sensor, this will come in a future update of this page.

Management of automatic watering (at 10 p.m.)

It is programmed in the rules of the Sonoff 4CH Pro an automatic trigger at 22h. By default on ignition, the blue LED lights up and watering is automatic. The Sonoff 4CH Pro can handle watering alone (without Jeedom).

I will soon add a check on humidity, probably a future update of this tutorial.

To order from Jeedom and easily integrate it into a design, I made a virtual ‘Automatic Watering’.
