Arad / Master Meter water utility meter #244

Closed avicarmeli closed 1 year ago

avicarmeli commented 2 years ago

I am trying to add a decoder for Arad/Master Meter water utility meter to rtl433 with some success. I was able to read meter's serial number and water counter as I posted here. I wonder, maybe with your experience with other meters you can help decoding the rest of the massage?

bemasher commented 2 years ago

From your captures, can you tell me what the modulation is?

avicarmeli commented 2 years ago

It is Manchester NRZ IEEE.

bemasher commented 2 years ago

Hmm, can you provide some sample captures?

avicarmeli commented 2 years ago

Do you mean other than what I posted here.?

bemasher commented 2 years ago

I mean IQ data, if possible.

avicarmeli commented 2 years ago

You can find here some data.

@avicarmeli Were you able to make any progress here? I'm working through trying to get data from a Master Meter and am trying to replicate some of your work here.

avicarmeli commented 1 year ago

@nickrobinson you can take a look at what I have by now here. It is still a work in progress.

@avicarmeli Are you still working on this? I've suddenly become very interested in being able to read my (Master Meter) water meter.

avicarmeli commented 1 year ago

Hi Josh

I ended up just compiling very limited version of the driver since I can only read the water consumption and could not decode the rest of the massage.

It works fine for me to read the water counter.

If need any specific help don't hesitate to write me.

One more thing is that I might made the preamble longer in order to read only my meter , so in that file you might want to change line 48 to shorter preamble or to one which comply to your 's meter serial number.

Mindful commented 1 year ago

@avicarmeli This makes sense - ultimately if I can read consumption that will be enough for me as well, so I think I'm just going to have to buy a dongle and play around with it. Thanks for your work on this!

I'll let you know how it goes, although that will probably be at least a few weeks out.
