feat(ev): use Spain official charger registry instead of crowdsourced data - #122
Conversation
… data Mapa REVE is the registry every Spanish charge point operator is required to file into, so it is authoritative where Open Charge Map is crowdsourced. The API allows 5 requests per hour at 100 locations per page, so a full pass over the ~14.5k-location registry takes about 30 hours. The scraper does not attempt a full sync: each hourly run fetches a few pages and the database fills in the background. The page window advances by wall clock rather than a stored cursor, so it needs no new table and resumes in place after a restart or redeploy. 92% of REVE locations sit within 50m of an existing Open Charge Map row, so the two sources must never both run for Spain. Open Charge Map stops being scraped as soon as a REVE key is configured, and the rows it leaves behind are removed once REVE reaches 95% coverage - not before, or Spain would show almost no chargers for the length of the backfill. Without PUMPERLY_REVE_API_KEY nothing changes.

Enforce the REVE request budget.
A value such as PUMPERLY_REVE_PAGES_PER_RUN=6 makes one scheduled run issue six requests. This exceeds the five-requests-per-hour limit and produces an avoidable HTTP 429. Clamp the value to four to preserve the stated manual-request reserve. Add boundary tests for invalid and oversized values.
Proposed fix
const rawPagesPerRun = Number(process.env.PUMPERLY_REVE_PAGES_PER_RUN ?? "4");
const PAGES_PER_RUN =
- Number.isFinite(rawPagesPerRun) && rawPagesPerRun >= 1 ? Math.floor(rawPagesPerRun) : 4;

Require the full configured coverage threshold.
Math.floor(totalCount * ratio) permits retirement below the configured ratio. For example, 13,787 / 14,513 is below 95%, but this condition deletes the OpenChargeMap rows. Use Math.ceil and update the threshold test to require 13,788.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Use localized fallback station text.
"Punto de recarga" becomes the persisted, user-visible station name when REVE provides no CPO name. Use the server-compatible custom t() path for this fallback instead of hardcoding Spanish text.
As per coding guidelines, user-facing strings must use the custom i18n system (useI18n() / t()), never hardcoded strings.

Source: Coding guidelines
PUMPERLY_REVE_PAGES_PER_RUN above 5 guaranteed that every surplus request was spent on an HTTP 429 - pointless, and rude to a free public service. Values are now capped at the published limit. Also corrects the backfill estimate. The ~30 hour figure is the floor at 5 requests/hour; the shipped default of 4 pages per run takes about 37. And the docs said the OpenChargeMap rows are removed "once the backfill is complete" when the actual trigger is 95% coverage, with both sources visible until then.

All three findings were correct — fixed in 14b3794. Page budget — clamped to the published 5/hour ceiling rather than to 4, so the knob still does something useful but can never ask for requests the API will refuse. Two boundary tests added: Backfill estimate — this one was a genuine inconsistency in my own numbers. 146 pages at the shipped default of 4 pages per hourly run is ~37 hours; the ~30 hour figure is the floor you only reach at 5 requests/hour.

@jmontane pointed out in #121 that Spain has an official EV charger registry — Mapa REVE — while Pumperly was showing crowdsourced Open Charge Map data instead. Every Spanish charge point operator is required to file into REVE, so it is authoritative: real operator names, real addresses, connector power, and a
last_updatedthat moves daily.This makes REVE Spain's EV source.
The awkward part: 5 requests per hour
100 locations per page, ~14,500 locations, no bulk export. A complete pass takes about 30 hours, and that is a hard floor, not a slow implementation.
So the scraper does not attempt a full sync. Each hourly run fetches a few pages and upserts them; the database fills in the background. That is safe because station upserts are idempotent and EV chargers are never orphan-cleaned, so partial fetches accumulate instead of wiping each other out.
The page window advances by wall clock:
A pure function of time, so there is no cursor to store — no new table, no migration, no state file. A restart or redeploy resumes where the clock says, instead of pinning the crawl to page 1 and never reaching the tail. Once a pass completes it keeps wrapping, which doubles as the refresh cycle.
Duplicates, and why the handover is delayed
92 of 100 sampled REVE locations sit within 50 m of an existing
ocm-row (measured with PostGIS against the live database). Running both sources would double-pin roughly 13,000 Spanish chargers.So Open Charge Map stops being scraped for Spain the moment a REVE key is configured, and the rows it leaves behind are deleted once REVE reaches 95% coverage — not before, because the 30-hour backfill would otherwise leave Spain nearly empty of chargers for over a day. The threshold decision is a pure function (
shouldRetireOcmRows) so the one thing that deletes ~19k rows is pinned down by tests.Without
PUMPERLY_REVE_API_KEYnothing changes: Spain keeps using Open Charge Map exactly as today.Also here
