Reading Vitens Watermeter (Sensus 620)

[raymonvdm]

Some time ago my water company (vitens) has replaced my water meter and now i would like to know if it`s possible to read the usage of it.

This is the meter

Deze meter kan je met een RFXMeter met reflective sensor uitlezen. Plaast de sensor boven het wieltje dat voor de helft uit metaal en de andere helft uit rood plastic bestaat.
Helaas is de RFXMeter op dit moment nog niet leverbaar. (proto hopelijk volgende maand)
Heb je al een RFXMeter dan kan je de RFXPulse met reflective sensor er wellicht nog bijplaatsen.

Sorry, here the translation:
This water meter can be read by the RFXMeter with reflective sensor. Stick the sensor above the metal/red plastic wheel.
The RFXMeter is expected next month (proto version)
If you own an RFXMeter you can probably install an RFXPulse with reflective sensor.

To install the sensor:
clean the surface with alcohol, dry the surface using a hairdryer, stick the reflective sensor.
If the water meter is in a high humidity environment you can use special 2 sided tape (car supplies shop) And if necessary fix the sensor with a tie-wrap.

I have a meter like this.

Will you tell us, when the RFXMeter is available? (In English. )

Is it possible to be one of the beta testers for the RFXMeter ?

I found a pdf

I will post a message in the RFXCOM Hardware forum as soon as the new RFXMeter proto is available

I never took the next step regarding the watermeter, but now i found this one. Which seems to be doable since i recently discovered Arduino / ESP8266

I restarted this project last week, but without much success so far. At first i tried to use ESPEASY as a pulse counter but the ESP Easy seems to be missing a lot of pulses. Since i`m no arduino guru i`m still strugeling to get soms sort of ino file working

I will try this one later on https://github.com/incmve/Sensus-waterm ... rmeter.ino

And already tried these one

I`m using a NodeMCU and this sensor. The sensor connects the GPIO to ground when counting a pulse. I have ordered 3 of them (NPN Type). But one sensor is the PNP type which gives me 12 volt when counting a pulse. The pulse couting seems to be running fine, en the output seems to be a nice block (no ripple)

The PNP is also tested with this schema


I would like to have a sensor which will send the data using MQTT and HTTP Post for Domoticz
