Hey everyone, I wanted to share my recent experience setting up a smart water monitoring system using a proximity sensor and ESPHome. It’s been a fascinating project, and I’ve learned a few things along the way that might be helpful for others!
First, I set up a pulse meter to track water consumption. I added a debounce filter to the main sensor to eliminate any pulse outliers, which can happen due to sensor noise or other environmental factors. My configuration looks like this:
yaml
sensor:
- platform: pulse_meter
pin: GPIO33
name: “Live Water Consumption”
unit_of_measurement: “L/min”
accuracy_decimals: 3
filters:- debounce: 0.3s
total:
name: “Total Water Consumption”
unit_of_measurement: “m³”
device_class: water
state_class: total_increasing
accuracy_decimals: 3
filters:
- multiply: 0.001
Now, my question is: Should I also add the debounce filter to the total sensor? I’m not entirely sure if the total sensor relies on the main sensor’s data or if it operates independently. Adding the debounce to both might be redundant, but I want to ensure accuracy across the board.
Another thing I wanted to mention is the importance of visual editors when working with Home Assistant. I recently switched from using vi to VS Code with the ESPHome extension. It’s a game-changer! The syntax highlighting and auto-completion make it much easier to spot errors and understand the configuration files. If anyone is still using terminal-based editors, I highly recommend giving VS Code a try—it’s free and runs smoothly on Mac and Linux.
Lastly, I’d love to hear from others who have implemented similar water monitoring systems. What challenges did you face? What tips can you share for ensuring reliable sensor readings? I’m particularly interested in how others handle sensor noise and data accuracy. Let’s keep the conversation flowing!
Happy tinkering!
