Device Support for Aquastream M Bus 868MHz (T1 Mode) #1807

Open nie3mals opened 3 years ago

nie3mals commented 3 years ago

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:

currently with:

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

I get this info:

time : 2021-09-15 20:40:07 model : Wireless-MBus Mode : T Manufacturer: IMT ID : 10025571 Version : 5 Device Type: 0x0E Device Type String: Bus/System component Control : 0x44 Data Length: 71 Data : 4444b42571550210050e7287545505b4250107720030254dcb7063b83c7dbc6468d4e8a7055462e2dcc77b6f6c34e5ed03677ad306aa0bfb30e45955d584653f5ed34675715425ac07 Integrity : CRC Control Info: 0x72 Access number: 0x00 Device Type: 0x00 Configuration Word: 0x0000 Volume flow[1]: 17602209457.588 m3/min Energy[0]: 0.000 MJ

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.

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.
