Landis & Gyr Focus AXR-SD Power Meter

[MauriceB13]

I understand that this has come up in the past and there seems to be quite a demand for RTL-SDR support for the Landis & Gyr Focus AXR-SD meter.

I have a Landis+Gyr FOCUS AXR-SD FORM 2S CL200 240V 3W 60Hz TA=30 Kh 7.2 Trilliant Networks RES-30000-FocusAX Securemesh 1w FCC: TMB-G30Focus IC: 6028A-G30Focus.

I have attempted using RTL_TCP and RTLAMR and RTLCAP to see if my meter can be picked up without success.

I would really like to figure this out and be able to read the data from this meter.

I am willing to do whatever is needed to facilitate this with your guidance @bemasher. Could we collaborate on this?

Thanks,
Ray

Thank you for sharing your project! I'd like to integrate it with my OpenHabian system to monitor power usage. But for initial testing I installed it on a Win10 Intel desktop.

With SDR# I can see/hear brief data chirps every 17 seconds at 914.889MHz and 915.040MHz (simultaneously). But no data is dumped while in rtlamr.

I've experimented with the msgtype and tried all 5 formats. I also tried centerfreq 915040. No luck so far.

My power meter is a Landis & Gyr Focus AXR-SD, FCC ID OWS-NIC507. After some searching I found the github discussion in closed ticket #55 that explained this meter is not supported if it is using an encrypted communication method. A confirmation would require checking the FCC ID info.

I checked the FCC database and could not find any reference to the communication protocol. Do you mind looking to see if there is hope of adding it as a supported meter? Here's a direct link:

Interesting. I was just looking at this tonight, and have a similar module (different FCC and IC).

Yours (which includes a manual): https://fccid.io/TMB-G30FOCUS
Mine: https://fccid.io/SDBLGZ1000

One difference, is I see that mine comes with Zigbee - I'll need to see if I can get my hub to connect with it.

Like the previous issues regarding this and other similarly flavored meters, support will not be added to rtlamr.

See https://wiki.recessim.com/view/Main_Page for information about possibly listening to these meters.

If I may ask, is there a reason why support won't be added to rtlamr? It looks like there is already an addon for GNU Radio, and I think it's be great to have it incorporated in the lightweight rtlamr as well.

These have entirely different demodulation and decoding requirements. Rtlamr is lightweight because all of the DSP is tailored to the specific requirements of ERT and ERT-like systems. I don't have access to any of these meters, so I have no way to test or support them.

Rtlamr is more or less feature complete for my original use case and should be considered to be in maintenance mode.
