Water flow sensor with ESPhome as "simple" water meter?

[bipsen]

Hi

I am wondering if it somehow is possible to utilize ESPhome in building a simplified water usage meter ?

I am thinking about using an YF-S201 or YF-B6 water flow sensor - but the challenge is, that these outputs a signal based on the water flow (HZ = 7.5 pulses per l/minute for YF-S201 and 6.6 pulses per l/min for YF-B6)…

I am not interested in the flow rate - more the water consumption (how many liters has passed through the sensor - total increasing (which might be reset of the ESP device is reset - so an utility meter probably needs to be added as helper) )…

What would be the best approach - if possible ? Or has someone already made a simplified water-meter using this method ?

Is it in principle just a matter of counting the pulses ? So that every pulse on YF-B6 in principle corresponds to 0.1515L water (1/6.6) ?

Guess you could start here:

Using ESPhome to build a water flow rate meter

Greetings fellow humans, I wish to build a thingy that tracks the flow of water from our borehole pump to the tanks. I am using a Wemos D1 R2, and a YF-DN40 water flow sensor (the big one). I notice that ESPhome has a Pulse Counter, which is basically how a flow meter works: there’s an inline rotor with a magnet in it, and a hall sensor that notices when the magnet comes round again. Before I go barking up the wrong tree, is the Pulse Counter the right component to use? I could hack something …

The esp will need the flow rate to sum it up for you but obviously you don’t need to expose the flow rate to ha if you don’t want
