Since a short while, I'm the owner of a RFXmeter with three modules (thanks Bert for helping me out). I've succeeded to calibrate the gasusage and to link it to Homeseer.
To measure my waterusage I apparantly need a reed-relais. I've got the same PIDPA watermeter as depicted on this website: http://www.domoticaworld.com/projects/monitor-water/. Could someone help me as to which reed-relais I should buy and how I should connect this physically to the watermeter as well as to the rfxmeter?

ill pm it. didnt pay attention it was in english

Thanks Vincent for giving me some background. Would this Conrad reed relais be what I need?

Thats to expensive.

How fast do you want this sensor, do you have the patience to wait 1 - 3 maybe 4 weeks ?
and its even cheaper when you buy like in the url you gave a Klik aan klik uit deur sensor.


That contains a small glass tube reed switch that should also work.
here you have some cheaper ones, not sure if you need NO or NC but i think its NO.

Also on ebay you can find these and others.

As with all gadgets, preferably yesterday
Besides the price, would the conrad reed relay be the right one (as it is already finished for my type of electronics knowledge)...

i think it should work yes but its a expensive gamble , t be 100% sure you can better ask Bert for confirmation but i'd say yes it should do the trick.

Thanks for your help.
Needed to order several things at Conrad, so thought would give it a try.

I received the Reed Relay today but wonder how I should connect this to the jack plug. There is a blue and a yellow wire on the relay and if I read the manual of RFXcom I should connect these to pin 2 and 3 of the jack plug. Some questions I have:
- Should these be soldered or can I just wire these?
- To what connectors on the jack plug should these be linked?

Recently I could buy a second hand RFXmeter with RFXpulse and a reflective-optical sensor. Goal is to read out my water meter which is a Itron Aquadis+ with a spinning wheel that is partly red and partly silvergrey. After some trial and error: placing the sensor on the right place and taping it very well and playing with the potentiometers P! and P2 on the RFXpuls I have got it working. Although there is a slight difference between the liters/pulses via the RFXmeter compared to the Itron meter itself. The RFX gives approximately 1% too much liters. This is after monitoring this very close for a week.
Is it possible to get this better, if yes: how ?? Has anyone got this working reliable over a long period of time?

Alternative solution is to use a "Cyble sensor"" that is made for the Itron Aquadis meter. But this sensor cost 70-80 EUR. Anyone experience with this sensor ? Does this work 100% reliable ?

Any advice on getting more reliable measurements is very welcome !
