More SCM+ Support #2546

Open MiddleSiggy opened 1 year ago

MiddleSiggy commented 1 year ago

Would you be able to add some additional SCM+ support.

I can use the rtlamr software and retrieve my water meter readings (and those around me)

Sample: ./rtlamr -msgtype=scm+ 20:56:15.154621 decode.go:45: CenterFreq: 912600155 20:56:15.155415 decode.go:46: SampleRate: 2359296 20:56:15.155588 decode.go:47: DataRate: 32768 20:56:15.155718 decode.go:48: ChipLength: 72 20:56:15.155889 decode.go:49: PreambleSymbols: 16 20:56:15.156016 decode.go:50: PreambleLength: 2304 20:56:15.156140 decode.go:51: PacketSymbols: 128 20:56:15.156309 decode.go:52: PacketLength: 18432 20:56:15.156439 decode.go:59: Protocols: scm+ 20:56:15.156610 decode.go:60: Preambles: 0001011010100011 20:56:15.156777 main.go:124: GainCount: 29 {Time:2023-06-26T20:56:17.829 SCM+:{ProtocolID:0x1E EndpointType:0xAB EndpointID: 73227139 Consumption: 54239 Tamper:0x4900 PacketCRC:0xF9DB}} {Time:2023-06-26T20:56:57.829 SCM+:{ProtocolID:0x1E EndpointType:0xAB EndpointID: 73227139 Consumption: 54239 Tamper:0x4900 PacketCRC:0xF9DB}} {Time:2023-06-26T20:57:12.780 SCM+:{ProtocolID:0x1E EndpointType:0xAB EndpointID: 72149111 Consumption: 57860 Tamper:0x4900 PacketCRC:0x1348}} {Time:2023-06-26T20:57:13.943 SCM+:{ProtocolID:0x1E EndpointType:0xAB EndpointID: 75230233 Consumption: 122500 Tamper:0x2500 PacketCRC:0x6489}} {Time:2023-06-26T20:57:18.720 SCM+:{ProtocolID:0x1E EndpointType:0xAB EndpointID: 73738930 Consumption: 117555 Tamper:0x2500 PacketCRC:0x9D37}} {Time:2023-06-26T20:57:23.941 SCM+:{ProtocolID:0x1E EndpointType:0xAB EndpointID: 75230233 Consumption: 122500 Tamper:0x2500 PacketCRC:0x6489}} {Time:2023-06-26T20:57:38.446 SCM+:{ProtocolID:0x1E EndpointType:0xAB EndpointID: 71784101 Consumption: 49973 Tamper:0x2500 PacketCRC:0xEE1A}} {Time:2023-06-26T20:57:47.827 SCM+:{ProtocolID:0x1E EndpointType:0xAB EndpointID: 73227139 Consumption: 54239 Tamper:0x4900 PacketCRC:0xF9DB}} {Time:2023-06-26T20:57:48.943 SCM+:{ProtocolID:0x1E EndpointType:0xAB EndpointID: 71784101 Consumption: 49973 Tamper:0x2500 PacketCRC:0xEE1A}} {Time:2023-06-26T20:58:02.780 SCM+:{ProtocolID:0x1E EndpointType:0xAB EndpointID: 72149111 Consumption: 57860 Tamper:0x4900 PacketCRC:0x1348}} {Time:2023-06-26T20:58:08.328 SCM+:{ProtocolID:0x1E EndpointType:0xAB EndpointID: 73227139 Consumption: 54239 Tamper:0x4900 PacketCRC:0xF9DB}} {Time:2023-06-26T20:58:09.221 SCM+:{ProtocolID:0x1E EndpointType:0xAB EndpointID: 73738930 Consumption: 117555 Tamper:0x2500 PacketCRC:0x9D37}} {Time:2023-06-26T20:58:18.943 SCM+:{ProtocolID:0x1E EndpointType:0xAB EndpointID: 71784101 Consumption: 49973 Tamper:0x2500 PacketCRC:0xEE1A}} {Time:2023-06-26T20:58:28.946 SCM+:{ProtocolID:0x1E EndpointType:0xAB EndpointID: 71784101 Consumption: 49973 Tamper:0x2500 PacketCRC:0xEE1A}}

I can confirm that my water meter is : EndpointID: 75230233

If I run "rtl_433 -M protocol -M level -M noise -M stats -f 915600155 -s 2359296 -g 0 -S unknown -R 154 -A" I get a bunch of SCM+ messages that are not decoded.

I saved the unknown samples and added them to the zip file here. 2023-06-26 - Samples.zip

Also this is the exact water meter transmitter documentation: https://www.itron.com/-/media/feature/products/documents/spec-sheet/101320sp03-100w-watercommmodweb.pdf

Let me know if there is anything I can do for you. Thank you

Generally there is nobody here looking at issues and digging in for devices they don't have. If rtlamr works, you should be able to submit a PR to enhance devices/scm_plus.c.

@MiddleSiggy Are you intending to work towards a PR? If not, I don't think it is helping the project to have this issue open, as the issue tracker is suffering from too many to be understandable.
