Alaxa Water meter
Hi,
I see for monitoring water, there is an option teh alaxa watermeter, with pulse. How do I connect it to for example a ds2423 (hobby-boards) counter?? Is it just one cable form the water meter to the dq of the ds2423??
Where can you buy such a meter?? What does it cost?
regards Richard

The cable coming from the water meter: 1 wire is connected to +5V, the other one is connected to A or B input, just pick one that's still free.

Price: Not that much. I can't recall anymore, bought too much domotica stuff...but it's not expensive, cause then i'd still remember.

I asked for price, it is 40 euro, for a cold water with pulse diameter 15mm
over the connection with 1-wire, is the a or b signal and the other one ground, and optional +5v for power? So form a water meter you have the signal, on a or b and than 5 v power? and no ground?

The cable coming from the water meter has only 2 wires, since all it is, is a switch actually; open most of the time, closing every x liter (depending on the version you have). One of the water meter wires goes into the +5V on the hobbyboards counter connector, the other one goes to either the 'A' or the 'B'.
You can use a small power adapter to supply the +5V or batteries maybe. And the - of that goes to the GND of the counter.
You can't do anything wrong.

Well i have the alaxa water meter, i guess the brown wire is the 5v and the white, de data dq?

My watermeter wire has Red & Black, so now you tell me...
Sometimes a drawing can say more then a complete white paper on this topic:
You could also connect the 'A' wire to the 'B'. But then you'll see another counter counting...

Digit,
I asked that i have different colors on my wires, but i doesn matter they said because it is a reed contact.
I going to buid it behind my water meter in my waterput this weekend, you will here from me

That's right that does not matter. once 0.5 liter of water gets through the Alaxa meter those wires get connected (pulse).
I think you have the same water meter as I have, bought them a couple of years ago with the same company.

Well it works..(soon pictures) now I have still a question, is there a tool or some other wat to reset the counters back to 0?
Alaxa Water meter
I'm not really sure perhaps depends on your type of 1-wire counter, try removing the battery? But why do you want to do that just start counting you have to handle it in your software anyway. Your 1-wire probably counts till around 65535 (see your technical specifications) and starts with zero again.

well this is the output
Dec 08 12:42:18 Sensor 0 C: 17.12 F: 62.83
Dec 08 12:42:18 Sensor 1 #0 360506
Dec 08 12:42:18 Sensor 1 #1 34865987
the biggest value is where the watermeter is put. The battery cr2032 is soldered, so not easilly to grab. It#347; a hobby-boards ds2423 dual counter

I Think you don't have a problem for a long while.
It has four 32-bit, read-only counters, 0 through 4,294,967,295 If I'm right, please other members correct me if wrong

Yes, the DS2423 has 4 32-bit counters.
But with the hobbyboards-counter you can only use 2 of them.
And AFAIK there is no way to reset the counters to 0 other then the way Pieter mentioned.

wel today I thought lets make it nice, and connect it to my domotica computer. So put some cat6 cable and make made it possible. Than I checked and it didn work, took another laptop form downstairs, and this works.. strange, everything tried and than I got the problem, the pc was domocitca pc was running on electricity the one that worked on battery. With som checking that is it, so I have a ground problem.
Now I have to solve it??
I using this scheme for the 1-wire, with the ds2423 form hobby-boards connected, with external power on the same randaarde
