Yes, it looks like it should be possible! However, you need the encryption key for your meter.
Do you have it already?

Hi, no I don't have it. How would I optain it? Is it per device or per vendor?

from wmbusmeters.

It is a device specific key that makes sure that you cannot listen to your neighbours water consumption.

There should be no harm in you having the key for your own meter.

You have to ask your water municipality/company that provided you with the meter if you can get your key. For the purpose of home automation and optimizimg your water consumption.

A lot of water companies/municipalities do hand out the keys.

So, the water company told me they cannot give me the key, because it is generic :(
That's it, I guess?

from wmbusmeters.

Yes, unfortunately.

Not a very good technical solution to have a generic key for all meters.

from wmbusmeters.

Alright, thank you.
I will have to recycle my rsa token ocr reader then ;(

But if you really need to monitor your water consumption, and want to reuse your wmbus dongle, you could buy your own meter that transmits using wmbus and then have it installed after the water municipalities meter.

If you find a nice meter, that is not supported by wmbusmeter, I can add support for it, as long as the meter conforms to the wmbus (and/or the OMS standard), ie no guarantees given for naughty meters like the apator162, techem and others that stuff proprietary stuff into the wmbus telegrams. :-)

Just for the record, same meter brand and same answer from the water company: the key is the same for all meters 😢
