User:Ctag/Landis+Gyr Focus AXRe-SD
ExecSum
My local utility company installed one of these doohickies on the house, and now I want to get realtime data from it after reading this article.
Device Info
The smart meter in question: Landis+Gyr FOCUS AXRe-SD FORM 2S CL200
Here is the official landing page for this family of products: https://www.landisgyr.com/product/focus-axe-axre-rxre-platform/
From this page I gather:
- The base product is called FOCUS AX. The AXe is a product refresh with better specs.
- Still no lead on the 'R' or '-SD' portions of AXRe-SD. I suspect 'R' is for reactive, as in it can meter reactive loads. Or it means Remote disconnect.
- Capable of remote disconnect.
- So as a consumer, I have an interest in these devices both giving me the data I want, but not being imminently pwnable.
- Built-in tamper detection
- OTA firmware updates (Cell? Mesh?)
- Some models have an optical port? IR?
- Two variations: Modular and Integrated.
- Modular: with or without AMI comms (AMI is Advanced Metering Infrastructure, but I'm not sure if this means ZigBee, 802.15.4, or something else?)
- Integrated: With radio built-in (I assume radio != AMI comms?)
Hash sent this link in discord, showing that the 'e' variants should have increased microcontroller specs: https://documents.dps.ny.gov/public/Common/ViewDoc.aspx?DocRefId=%7BBE3EBED1-4973-440D-A2BD-A28ED46F9FC1%7D

This meter won't be supported in rtlamr: https://github.com/bemasher/rtlamr/discussions/191

Meters without the top sticker do not have radios, apparently: https://www.landisgyr.com/webfoo/wp-content/uploads/2014/08/Info-Sheet-Focus-AX-Family.pdf
