Compatibility question - Landis+Gyr Focus kWh #156

Closed mrd0n closed 4 years ago

mrd0n commented 4 years ago

Hi - curious if the Landis+Gyr Focus KwH electrical unit is supported or if you think it could be?

The FCC ID is : https://fccid.io/ROV-CLTR900M

The manual for the unit is: https://www.solar-electric.com/lib/wind-sun/Focus-technical-manual.pdf

Thank you for this awesome contribution - my water meter and gas meter are being captured perfectly!

mrd0n commented 4 years ago

Adding some more info that is hopefully useful.

From the FCC document, the device frequency range is 913.98-917.58 MHz.

I've tried a capture using rtlcap -centerfreq=915M -tunergainmode=false -gainbyindex=29 -squelch=0.658 -bytes=25M -o capture-915M.cu8 capture.zip

I think the device ID is 40615079.

Added some photos. IMG_1310 IMG_1312

Your 100G should be compatible based on the label, but your Focus is likely not compatible. Based on the samples you provided, it does not contain any messages from your gas meter.

Below is a test to decode the samples you provided.

package main

import (
    "io"
    "os"
    "testing"

    "github.com/bemasher/rtlamr/idm"
    "github.com/bemasher/rtlamr/protocol"
    "github.com/bemasher/rtlamr/scm"
)

func TestRead(t *testing.T) {
    sampleFile, err := os.Open("capture-915M.cu8")
    if err != nil {
        t.Fatal(err)
    }
    defer sampleFile.Close()

    d := protocol.NewDecoder()
    d.RegisterProtocol(scm.NewParser(72))
    d.RegisterProtocol(idm.NewParser(72))
    d.Allocate()

    block := make([]byte, d.Cfg.BlockSize2)

    for {
        // Read new sample block.
        _, err := sampleFile.Read(block)
        if err == io.EOF {
            break
        }
        if err != nil {
            t.Fatal("Error reading samples: ", err)
        }

        offset, _ := sampleFile.Seek(0, os.SEEK_CUR)

        for msg := range d.Decode(block) {
            t.Logf("%9d %T %+v\n", uint64(offset)>>1, msg, msg)
        }
    }
}

This is the output.

Thank you for your time! Bummer on the Focus not likely being compatible.

The 100G gas meter is being decoded - yay!.

seancolyer commented 3 years ago

@bemasher do you know what the issue is here? Looking at a couple of the other tickets it looks like there's a variety of potential issues that seem to group around two classes:

Is that right? If it's the first issue, I was thinking about trying to dive in and see if I could possibly put something together built on your work, would that make sense to attempt?

bemasher commented 3 years ago

I have no direct experience with non-ERT meters, you are welcome to fork rtlamr and build support yourself. I don't have time or resources to support these meters in rtlamr, so it would have to remain a separate project.

bemasher commented 3 years ago

For the curious among you, this page has quite a lot of good information regarding Landis+Gyr meters and decoding the protocol at least some of them use.
