water meter

[dulka]

I would like to connect an instant water flow meter to the hall effect, someone can help me do it. I saw that a water flow meter already exists in the menu but I do not know how to connect it. Thank you

before we start giving suggestions, it would help that we know what type of water meter you have and with which device you want to measure this.
That helps in giving correct suggestions and others might even give better solutions to your problem.

You're right, my domoticz is installed on Raspberry PI3 and as a sensor I would like to use a hall effect that produces pulses that increase in frequency as the flow increases like this: https://www.amazon.it/filettatura-effet ... flow+meter

Thank you

A help at least starting then I try to understand by myself, thanks

I would install ESPEasy on a NodeMCU, connect the sensor to one of its GPIOs, and set up ESPEasy in such a way that it sends the data to Domoticz. You can use the device type "Pulse Counter" for this. You can even assign a formula to calculate how many litres a single pulse is. There are guides to explain the steps in detail, I think the ESPEasy website also has some info.

I did this with an optical contrast sensor (TCRT-5000) on my "classic" water meter, works perfectly.

Resolved, this site has been very helpful: https://www.letscontrolit.com/wiki/index.php/ESPEasy explains how to use ESP8266. Recommended for everyone
