Giá đỡ cảm biến đồng hồ nước

ESPhome code I've used:

sensor:

pin: 15 #Was GPIO13
use_pcnt: false
internal_filter: 100ms
id: water_pulse
name: "${device_name} pulse"
unit_of_measurement: "pulses/min"
icon: "mdi:water"
update_interval : 60s #1 pulse = 1L, if we run at 60s or 1min, we get L/min. So dont change the timing!
total:
name: "${device_name} Total"
unit_of_measurement: "L"
# Just for a history graph with usage lined per time
- platform: template

accuracy_decimals: 1
unit_of_measurement: "L/min"
icon: "mdi:water"
lambda: return id(water_pulse).state; #1 pulse = 1L
