Because you have twice the same definition
So I also have a Neptune T10, am in the US. I’ve tried the sensor as well and I never get any pulses. I know this meter is compatible with Flume. I wonder what they use as a sensor??

I have the meter in the picture included. I am not able to get a signal using a proximity sensor. Where I can find the spinning magnet?

Hello everyone,
First of all, I would like to mention that I am a complete novice in this matter, so I ask for your indulgence.
My english isn’t that good either, hence the google translation
I realized the project with an ESP8266 the LJ18A3 sensor.
The results are also arriving in the Home Assistant, I have copied the code and it can certainly be improved, suggestions are welcome.
My problem (see graphic) are these deflections after which I would consume 60000l or 12000l.
I have no explanation for that, my wife also thinks the amount of water measured is not correct (manual comparison)
Now my question to the community, hoping for help.
How do I calibrate the sensor?
Where do the “freaks” come from?
Is the sensor placed correctly?
The sensor and the ESP are powered by a branded USB power supply.
Hope you can help and thank you in advance.

After the most recent update of ESPhome some tweaks to the water-meter code may be required, relating to the multiple usage of the same pin. This code fixes the errors, unfortunately unable to test whether it affects the sensor readings.

This indeed solved my issue with multiple Pin usage. Thx

Based on some comments in a previous thread, I suppose getting rid of the pins being used twice would be better. Since the introduction of Water into the Energy dashboard, only one entity would be sufficient:
sensor:
- platform: pulse_meter
pin:
number: GPIO12
name: "Water Pulse Meter"
unit_of_measurement: "liter/min"
icon: "mdi:water"
total:

I have followed the original setup of this water meter, after changing the “allow_other_uses” it worked but then came across your single sensor setup which makes sense.
However I get very weird numbers.
According to the “water meter total” I already consumed 27.684 m³ in the last 10 minutes. (dish washer and testing water at the faucet)
27m3 is 27 000 liters of water, which is bonkers. I assume there is something wrong with either the “multiply” for my setup, or the actual sensor changed its output? I’m using the same one as the OP.
Great coding @MJV
Thanks for the update!
I made the sensor and works straight after first try.
Question: I would like to implement the real water sensor count which increments the usage in a counter. This has two usages: calibration of pulsecoding and logging of watermeter. How would one achieve this?
which ESPHome YAML code is the most current in 2024?
when using the code form: Build a cheap water usage sensor using ESPhome and a proximity sensor - PieterBrinkman.com doesnt work anymore

I recently used this one: https://github.com/geertmeersman/energie-meter/
I used a Wemos D1 clone as I already had it.
I dont have a gas meter, so left that one out.
Also, in the utility meter yaml example you need to specify the ESPhome sensor, not “sensor.water_used”.
After calibrating, works like a charm!

@rda great, can you show me the yaml config for esphome.
And how dou you count the actual value of the watermeter?
I got LJ18A3-8-Z/BX NPN?
I have a Badger Meter 62584-020 Recordall Transmitter Register.
Data sheet suggests magnetic (metal) disk nutates to transfer to other magnetic disk…etc
It detects metal, the copper pipes, the metal to the frame of my desk…etc.
But couldnt for the life of me figure out where the sensor/disk was. Is it possible the disk is not metal/magnetic? the Glass/plastic isnt as thick as I feared and was really really hoping this would work as my water bill spiked huge last bill and was hoping to get independent monitoring to corraborate and troubleshoot?
Do I possibly need the PNP one instead?
If this doesnt work, what other use cases can I repurpose this sensor???

I uave a question on this.
I have a meter with 1 pulse per gal and its counts the gallons correctly, but the gallons per minute do just show 1 x 12 gal/min and then nothing again while water is running. And still counting the gallons up.
Here my code:
sensor:
- platform: pulse_counter
pin:
number: GPIO14
inverted: true
mode:
input: true
pullup: true
name: "${upper_devicename} Flow"
unit_of_measurement: "gal/min"
icon: "mdi:water"
update_interval: 5s
accuracy_decimals: 0
internal_filter: 400ms
count_mode:
rising_edge: DISABLE
falling_edge: INCREMENT
filters:
- lambda: return (x);
total:
name: "Total Water Consumption"
unit_of_measurement: "gal"
device_class: water
state_class: total_increasing
accuracy_decimals: 0

Is there anything obvious that i am doing wrong?
Thx gor any thoughts

I did not change the common yaml files from the repository other than refering to my own secrets.
Seems like it, you have one with the metal plate, so try if the sensor led blinks if you hold the sensor above that one.
I thikn that if there is a metal disk, it would be deep inside, where an external sensor would not detect it. Also, it seems like this meter already has a digital output? Can’t you use that insted? Or search the web for an optical sensor solution which can detect the digits or other indicators on this meter.
