rtl_433

Hi all, I have a Water reader from Aquastream which supports remote reading on 868MHz.

According to the specs and this details, the sensor should support to report the following:

• current reading
• current flow
• batterylife
• some more info

currently with:

rtl_433 -D -G 4 -f 868900000 -s 1600000 -v

I get this info:

where the sensor Id is correct, the volume flow is wrong and some other info is missing.

any idea how to include also the other readings like the current clock reading? I am happy the share samples if someone can support me. bear with me, I am quite new in this topic! thanks!

I would recommend the https://github.com/weetmuts/wmbusmeters project for this use case.

If you post a signal sample rtl_433 might also add support for this sensor. In that case use rtl_433 -f 868.9M -S known to record signals.

@merbanan , thanks for your comments! It would be great the see rtl_433 supporting this device. attached some sample data. incase further files are need, I am happy to share those. since its convenient, I uploaded the samples here as zip file. please let me know if you need those also in RTL_433_test thanks for any help!

many thanks!

Hi all, any help or suggestion would be appreciated. I am happy to close also the issue if the request for the device support is not appropriated.

@nie3mals What's the status and plans? Are you going to work on a PR that would add a decoder?

@gdt, would like to. but I need to have here support. are you able to help me out. not yet on that techincal skill level ;-)
