, 23 September→Device Info: Added remote disconnect idea.
My local utility company installed one of these doohickies on the house, and now I want to get realtime data from it after reading [https://pdx.su/blog/2024-03-17-reading-my-electric-meter-with-rtlsdr/ this article].
=== Device Info ===
The smart meter in question: <code>Landis+Gyr FOCUS AXRe-SD FORM 2S CL200</code>
From this page I gather:
* The base product is called FOCUS AX. The AX'''e''' 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 [https://www.theelectricalguy.in/tutorials/active-reactive-apparent-power-easiest-explanation/ 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
