The settings card stops emptying when one message is late
A snapshot has two halves and they travel separately: telemetry comes from the trigger, the settings only when the charger has something to say about itself. A read can land with the first and not the second — most often the first read after a reconnect — and the card was seeded from that answer alone, so it collapsed to the one control telemetry happens to carry. That is the state of one message, not the state of the charger. Three things, from the outside in. The card keeps what the charger has reported, per serial, across reads. A value stays until another replaces it. They are its own last word either way, and the same ones the server fills a grouped command's siblings from when a caller leaves them out. A charger that goes quiet is no longer written off for good. The miss counter decides whether a read waits for the settings frame at all, and it only ever rose: three unanswered requests early on and no later read waited again, however freely the charger answered afterwards. The comment said "recently enough"; the code said "ever". Answering clears it now. And the first settings are worth the wait a settings write already gives them. Stale settings and never-reported settings were both allowed four seconds. Stale has something to fall back on; never-reported is the empty card, so it gets the full wait — still bounded by the miss counter, so a charger that truly never answers costs it three times and no more.

A field we have no name for is still a field it sent
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. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> |

Go the way the owner's phone already goes
Control had two transports and neither fitted the ordinary customer. OCPP waits for the charger to dial in, which needs a public endpoint it can reach, a certificate, and a firmware willing to talk to our CSMS. Modbus TCP dials the charger, which needs the server on the charger's own network. Between them they cover a charger we host and a charger we stand next to; the common case is a charger behind someone else's router, and that had nothing. It was never unreachable, though. The charger holds a connection open to Anker's own broker — it is how the mobile app drives it from anywhere, and it is the mqttStatus register the Modbus snapshot has been reporting all along. So a third control mode joins that broker as the account: get_user_mqtt_info issues a client certificate, mTLS to aiot-mqtt-eu.anker.com:8883, and commands go out on the same topics the app publishes on. Nothing on the customer's side has to be forwarded, addressed or certificated. What travels is not an API call. The payload is a JSON envelope around a base64 binary frame the device itself speaks — marker, little-endian length, message type, name/length/type/value fields, XOR checksum — so mqttframe.go is a codec rather than a client, written from the message maps in anker-solix-api and anchored on the one frame that project documents byte for byte. A frame whose fields do not tile exactly up to the checksum is refused rather than half-read: these arrive over a link we do not control, and a truncated frame must not read as a charger reporting zeros. Two of the charger's habits shape the rest. It publishes nothing unless asked, so a status read arms a telemetry trigger and waits for the next frame, and a poll inside that window answers from what has since arrived. And a broker connection costs a fetched certificate and a TLS handshake while the plugin manager builds a throwaway instance per request — so the connection lives on the account's shared session beside the auth token, for exactly the reason the token lives there, and closes itself after five idle minutes. The transport also sees two signals no other one does: the boost flag, and the plug and start countdowns. The package doc has said since the first commit that they are never set and the derived mode must do without them. Here they are set, so a charger that has been told to start and is counting down a delay says so rather than sitting in "preparing", and "skip the delay" is offered only while there is a delay to skip. The clients generalise instead of growing a second layout. Both snapshots name the same quantities the same way, so what was Modbus-only in the readouts is now whichever transport read the charger — ModbusStatus becomes ChargerStatus on the phone, mb becomes dev on the web. What each transport can be *told* still differs, and the buttons branch on that: reset and clear-limit stay with OCPP, the timeout and phase registers with Modbus, skip-delay with the cloud. A command a transport has no equivalent for is refused by name, saying which one has it. The cost is worth saying plainly. This leans on Anker's cloud being up and on an unofficial protocol the app may change under us, where Modbus leans on nothing but the LAN. And it is checked against the reference implementation's own worked example rather than against hardware — there is no charger on this end to point it at.
