You’re correct @Olivier974, the new ENERGY dashboard from 2022.11.1 is a better choice for global water usage. I will probably move that sensor there.

I will make a post soon summarizing everything. I will finish setting things up with @NoGrout as my code used Legacy Sensor configuration format and I want it to be more future-proof modern configuration format.

thanks!
cant wait for it 
Could you post your config?

For anyone who may be trying to integrate the Ultrasonic flow sensor TUF-2000M, I finally got it working with ESPhome yesterday: TUF-2000M Ultrasonic Water Flowmeter MODBUS integration - #6 by newnub
Hi Vincent,
Very good job. Thank you to this share.
So, could you share your connexion schema ?
Best regards.
Merci d’avance
I will send a complete update very soon. I’m just very busy and don’t have much time to spend on preparing that post. But I will! Thank you @fabal45

Great. Thank you very much to this answer and the work.
Petite question pratico pratique, est-ce que ce type de mécanisme se fait ressentir sur l’usage ? J’entends par là, perte de pression ou encore nuisances sonores ?
I haven’t heard any noise and it does not seem to reduce flow. 
Logically it must slow flow a little, but it is negligible.

Can you share your sensor code for this meter? I am about to order one. Thank you in advance.
Hey friends,
maybe you can help me with this related use case. I want to go one step further and implement a heat monitor, which combines water flow with temperature differences:
Would love to discuss
hello everybody,
I bought the YF-B1 sensor
I’ve been struggling to figure out how to calculate the Liters/min and Liters/hour.
According to the datasheet F=11*Q
What are the two columns with numbers ???
Does it mean 2 liters > 22 pulses, 2.1 liters > 23.1 pulses ???
So far I have the following code for liters/hour but am not quiet sure if it’s right.
- platform: pulse_counter
pin:
number: 4
mode:
input: true
pullup: true
unit_of_measurement: 'L/hour'
id: water_usage
name: "Instant water flow"
update_interval: 5s
filters:
- lambda: return (x / 660); # 660 = 11 * 60 min
Is this correct ?
Anyone please ??
I need to finish the project and have the wife happy …
I think that’s what the datasheet is saying.
Hi!!
I have bought for my installation a sensor similar to yours but the exact model is the following YF-B10 and I can’t understand what would be the necessary adjustment to calibrate this sensor, that is, the lambda that I have put, could you help me?
I’ll post the specs here.
(6 * Q-8) Q= L/Min ±5%
What would be the setting for my sensor. Thank you, I hope it arrives so I can configure it.
Maybe you could try the following:
sensor:
- platform: pulse_counter
pin:
number: 4
mode:
input: true
pullup: true
unit_of_measurement: 'L/min'
accuracy_decimals: 2
id: water_usage
name: "Instant flow rate"
update_interval: 5s
filters:
- lambda: return 6 * (x / 396) - 8;
Let me know if it returns correct values.

Ok, Thank you.
I am waiting for it to arrive, I have the board ready and with the configuration ready to load. And when it arrives I will try to imitate your config, I found it very interesting.
Greetings!

I have been looking at the whole post, I am waiting for a sensor with similar characteristics to the one used by you (@NoGrout , @donparlor ) and it is very long and difficult to understand, there is the possibility of sharing the complete code, that is, everything that refers to this automation, sensors, automations, input_numbers, binaries etc… thanks!
Hello valsergi, despite many attempts and the help of Donparlor, I have not managed to get consistent data. I’ve been using the energy_water module since a recent update, unfortunately the data isn’t consistent either. I had many other occupations in the meantime, and I left this function aside. I remain very interested in this subject.
