Hey everyone, I wanted to share my recent project with the pulse water meter setup. It’s been a great addition to my smart home, and I thought I’d walk through my experience in case anyone else is looking to implement something similar.
The Problem:
I was trying to monitor my water usage but found that proximity sensors didn’t work well with my grid water meter. The plastic wheels made it unreliable. After some research, I decided to go with a pulse flow water meter from Amazon. It was a bit of an investment, but I think it’s worth it for the reliability.
The Solution:
I chose the Systeme-Sh pulse flow meter with 88 pulses per liter. It came with a resistor, which was a nice touch. I paired it with an ESP8266 D1 Mini and used ESPHome for the setup. Here’s the code I used:
sensor:
- platform: pulse_meter
pin: GPIO12
name: “Instant water consumption”
unit_of_measurement: “L/min”
icon: “mdi:water”
timeout: 1s
accuracy_decimals: 3
filters:- lambda: return (x / 87.0);
total:
name: “Total water consumption”
unit_of_measurement: “m³”
device_class: water
state_class: total_increasing
accuracy_decimals: 3
icon: “mdi:water”
filters:
- lambda: return (x / 87000.0);
The Results:
I’ve been running this setup for a few weeks now, and it’s been rock solid. The instant consumption gives me real-time data, and the total meter helps me track usage over time. The only thing I might tweak is the calibration, but it’s close enough for my needs.
Why I Chose This Approach:
I wanted something that was both accurate and easy to integrate with Home Assistant. The pulse meter doesn’t require complex wiring, and the ESP8266 made it simple to connect everything wirelessly. Plus, having the resistor included was a nice touch that made the installation smoother.
Tips for Others:
If you’re considering a similar setup, I’d recommend checking the pulse rate of your meter to ensure accurate readings. Also, make sure your ESP device is properly powered to avoid any hiccups in data collection.
I’m really happy with how this project turned out. It’s given me a clearer picture of my water usage, and it’s been a great learning experience. If anyone has questions or wants to share their own water monitoring setups, I’d love to hear about them!
Cheers,
