Platform is identified by characters 6-8 of the serial number, and only
platform 105 (ES/EM/BP - ESU EMU ESA BPS BPU EMJ IJL) speaks the AA55-era
meter bus this product emulates. The reference unit is 95000BPS225W0290 -> BPS.
Everything with a "-20"/G2 suffix is a different platform: SBP G2 (SPB/SPN) and
ES G2 (ESN/ESC) are platform 745, ET/EH/BT are 205/745/753. PV-only inverters
(SDT/DST/MSU/NSU) have no battery to control at all.
Added as the first item in Step 0 of the field guide, because it is a 60-second
check that decides whether the job can be quoted, and as a table in the README.

Rebuilt the guide as something usable on site rather than a document to read
at a desk: strict order of operations, DO / VERIFY / IF NOT blocks per step,
pass-fail gates in a table, a printable sign-off sheet, and troubleshooting
keyed by symptom rather than by subsystem.
Includes real screenshots of the add-on's own Web UI - captured by running it
against stub data - showing the healthy state and the misconfigured one side
by side, because telling those apart at a glance is the single most useful
skill on site. Plus the ESPHome step from a live builder.
The text lives only in docs/build_guide.py, which renders the HTML and drives
headless Chrome to produce the PDF. One source: a Markdown copy would
inevitably drift from the PDF someone is holding in a cellar.
Pagination is enforced, not hoped for. Each section must render under the A4
printable height (1039 px at 96 dpi) or Chrome silently spills it onto a second
page and the page numbers stop matching the step numbers. Measured every
section rather than eyeballing it: the Web UI reference page was 1170 px and is
now 1017 px, and the PDF comes out at exactly one page per section.
