Hi!
Sorry about my english.
I created an automatic water tank filler for my Jura coffe machine( or whatever another water tank).
Used hardware:
1.Sonoff Basic V1
2. Rain drop sensor without plate itself,only litle PCB module (see pic below)
3. 220V AC magnetic solenoid valve
4. Some wires(for wiring)
5.Stiff stainless wire (for tank sensor)
6.Some connecting stuff for wires
7. Water hose from solenoid to water tank
Used software:
ESPHome,there is yaml:
binary_sensor:
- platform: gpio
pin:
number: GPIO14
mode:
input: true
pullup: false
inverted: false
name: "Coffesensor"
filters:
- delayed_on: 5s
- delayed_off: 500ms
on_press:
- switch.turn_on: relay
switch:
- platform: gpio
name: "Coffeswitch"
pin: GPIO12
id: relay
restore_mode: ALWAYS_OFF
on_turn_on:
then:
- delay: 40s
- switch.turn_off: relay
status_led:
pin:
number: GPIO13
inverted: yes
