Two cards on the Charging page were answering with a fraction of what the charger
and the account actually report, and in both the losses happened quietly, in a
parse that kept the fields it recognised and dropped the rest on the floor.
Charger information asked three account-wide views and kept fourteen fields.
A charger registered on its own is absent from the site view, which is the only
one of the three carrying state, charge power and OCPP status — so exactly the
charger that stands alone got the column of dashes, and nothing said why. The
per-charger station record, get_evcharger_station_info, is what the mobile app
opens when you tap a charger, and it is the one view that answers for a charger
outside a station; it is now the fourth view, asked per charger, a failure there
costing that charger's row and no more. Alongside it, every field each of the
four views sent is kept as attrs, under the cloud's own key, nested objects
joined with a dot and arrays carrying their index. First view to answer a key
wins, which is the rule the named fields already merged by. Two hundred keys and
two hundred and forty runes per value keep a station record with a session list
from becoming the whole card.
Charger readings lost data twice over. The frame decoder skipped any field byte
its per-message map could not name, and a message type with no map decoded to
nothing at all; those fields are now kept under the message and the byte they
arrived in — 0410.c9 — decoded but unscaled, because a factor is half of a
meaning and we do not have the other half. Then the projection read forty-odd
names into typed fields and dropped the remainder: sessionStartedAt, the
per-phase session energies, the three touch modes, the load-balance monitor and
its meter flag, the solar monitor. Those land in extra, and the list maintains
itself — the four accessors note every key they read, extra is what is left, and
a field modelled later stops appearing there without anyone remembering to
remove it.
Keeping unnamed fields had one consequence worth guarding. An unmapped message
now decodes to something rather than nothing, and ingest stamped settingsAt for
anything that was not telemetry — the timestamp a control command waits on to
say the charger acknowledged it. A frame we cannot read is not an
acknowledgement, so the stamp is now conditional on the message type being one
we map, while its fields are kept either way.
Both cards show the remainder as what it is: the service's own key, no unit, no
translation, no renaming, under a heading that says whose words these are. The
blocks appear only when there is something in them, so a Modbus charger's
readings card and a charger the cloud says nothing more about are unchanged.
Naming one of these fields is a later commit, made from evidence; inventing a
label for it today would only make a guess look settled.

get_user_bind_and_not_in_station_evchargers is the only list the connector ever
asked for, and its name says exactly what it withholds. A charger that belongs to
a system is not in it. Its userBindEvChargersCount, though, counts every charger
bound to the account — so an owner with two chargers in a system got "authenticated;
2 EV charger(s) bound to account" from the health probe and an empty list from the
capability that is supposed to show them. A working login that finds nothing.
So the capability now asks every view the cloud has and merges them by serial. The
standalone list still answers for chargers standing on their own; get_site_list
walks the systems and reads each one through get_scen_info, falling back to
get_system_running_info where that is silent — the power-service / HES split
charger-state already knows; and get_relate_and_bind_devices contributes model,
firmware and the Wi-Fi flag, and discovers anything in the A519 family that the
first two missed. Whichever way a charger was registered, one of the three has it.
The merge is first-writer-wins per field rather than last view overwriting: the
standalone record knows the name, the site record knows the live state, and neither
should blank what the other established. A view that fails is a warning on the
document instead of an error on the call, because one dead endpoint should not
cost the chargers the other two found. Only losing all three is a failure. When
nothing comes back at all the response says so in its own words and names the
remaining suspect — country picks the regional server, and the wrong one
authenticates happily and shows an empty account.
The other half of "not showing any chargers" was that neither client ever showed a
list. The serial was a text box, and the number is printed on a charger hanging on
a wall. Both apps now list what the account holds — name, serial, model, site,
state, an offline badge — and hand the serial to the OCPP control card instead of
asking anyone to go and read it. Where control is off the list still stands on its
own, as the answer to the first question an owner has after entering credentials.
