HI Florizz,
Dit you get your question aswered? I am struggling with the same. Even though it works with an ouput voltage of 4.8v volt for me, I am afraid that on the long run it will fry my ESP.
Hi there,
I know, that the post is somewhat older, but i have seen it because I found the idea great. Therefore for the first I really want to thank Pieter for the great Project and his work.
I have bought a ESP8266-12F. Unfortunately after about 3 months the card broke. Because of the post of Marcel1 I had a closer look into the technical specs. indeed they warn to operate it with 5V on the GPIO Pins, because it is not 5 V tolerant. If you operate it with more than 3,6 V will destroy the Chip so they write. Because I am not keen in electronics, I was searching the web and found something in the IObroker forum. George the guy, building the project for IObroker was introducing a voltage divider to reduce the voltage on the pin and a capacitor for eliminating disrupting factors.
Here is the link. It found it very interesting.
Perhaps someone is interested in the project even it is older now.
I used the code of @Frank_R and that works. Three new devices were created in HA:
Water Flow Rate
Water Usage
Water Usage M3
Hi Seb, did you find a solution for that Maddalena DS TRP water meter? I have the same.
Cheers

@Theeyeinthesky @Olivier974 long time ago… here my mounting for 3D printing yourself https://www.thingiverse.com/thing:7039889
I’ve got a 18A3-8-Z/BX NPN sensor (5VDC 300 mA). LED is blinking when I use water, but the output is around 5V which is too high for a ESP.
Are you using this without resistors?
@pbrink and and others… thanks for sharing the info in this thread.
I’ve just installed a water meter in my home pipework with a reed sensor and want to get the data into HA. I’m struggling a bit because, unlike all the posts I’ve seen here, I’m not using ESPhome as an intermediary. I’ve connected my meter’s pulse output to an EMS-ESP32 device which is monitoring my home heating system. This is then passing the pulse data to HA via MQTT…
Which I can then add to a card to see the on/off state changes…
I’ve disabled it in the recorder because I don’t need to keep the timestamped state changes!
So… I’d like to do a few things from there…
- Convert the pulse train into a litres/minute graph - hours and days I can get in the Energy dashboard
- Convert the pulse train into a metered value I can add to the Energy dashboard
How can I do this with my setup, please, rather than via ESPhome? Thanks!
Awesome project! Going to try this
For people interested in storing the usage total in flash mem to have it survive reboots, have a look at my writeup on adding a water meter to the SlimmeLezer WT32-ETH01.
Hey there,
I have the exact same meter and I tried today with a reed sensor, but I cant get a reading.
Did you manage to get it to work?
Thanks!
Did you ever get monitoring setup for your Water Meter? I have the exact same Recordall model.
No, at this point I’d just use the LLM integration to google or whatever and make it tell you. My area everyone has soft water tanks and it has to essentially for us weekly regenerate so i have a leak detecter that helps me validate its working and such which was my main goal. Getting anything else proved to be too much trouble for what it was worth for me.
