+Waveshare ESP32-S3-RS485-CAN running open3e-esp32 from the fork
+konairius/open3e-esp32, branch `feat/heating-curve-rw` (0.3.0+ea30668: upstream
+0.3.0 with the heating curves 880-883 writable, S28-55), on Vitocal 250-A socket A
+(Klemme 1 = CAN L, Klemme 3 = CAN H, no GND/shield, jumper H1 = NC).
+Replaces the `heating-can` stack on edge-1. YouTrack S28-28.
+
+- mDNS: `vitocal-can.local`
+- DNS (DHCP): `open3e.iot.renner.uno`. The firmware sends its compiled-in
+  `CONFIG_LWIP_LOCAL_HOSTNAME`.
+
+## Files
+
+- `settings.json`: apply with `PUT /api/settings`. No password: the MQTT
+  password is pushed by mqtt-account-controller.
+- `points.json`: apply with `PUT /api/points`. 127 UDS datapoints (30 s; buffer setpoint 1799 60 s; flow limits 1193/1194 300 s;
+  fixed topics matching the Home Assistant packages), including the 29 One
+  Base ZigBee slots on 0x6c3 (topics `onebase_<DID:04d>_<didName>`), and 7
+  E380 frames (10 s). Compact JSON with default fields omitted: the API takes
+  request bodies of at most 16384 bytes (`MAX_BODY`).
+
+## One Base ZigBee slots (ECU 0x6c3)
+
+The 29 slots need a firmware with open3e-esp32 PR #20 (codec trees in PSRAM,
+merged 2026-11-09, first in 0.2.0+2d9002b; S28-52). Without it a compiled
+codec stays in internal RAM for each polled point (allocations < 16 KiB are
+internal, `CONFIG_SPIRAM_MALLOC_ALWAYSINTERNAL`), one slot costs ~8 KB, and 29
+slots exhausted internal RAM (`internalMin` 16 B, crash in task `wifi`). Do
+not load this `points.json` on an older firmware.
+
+Home Assistant reads health from `/api/status` and `/api/sysinfo` (REST
+sensors in `packages/open3e.yaml`).
+
+Measured internal heap (`/api/sysinfo`, free / min in bytes):
+
+| Loaded | free | min |
+|---|---|---|
+| 0 points | 161,923 | |
+| 46 Vitocal | 115,163 | 73,040 |
+| + 29 VX3 | 114,067 | 49,228 |
+| + 16 VCMU + 7 E380 | 108,315 | 40,064 |
+| + 1 ZigBee slot | 100,295 | 39,828 |
+
+The hostname is part of the Wi-Fi settings: `POST /api/wifi`
+`{"ssid":"Renner IoT","hostname":"vitocal-can"}`. An omitted `pass` keeps the
+stored one.
+
+## Firmware update
+
+Build: in the fork checkout, `docker run --rm -v $PWD:/src -w /src
+espressif/idf:v6.1` with `make setup db fixtures test`, `make storage`, then
+`idf.py set-target esp32s3 build` (the last step packs `build/storage.bin`
+from `storage_image/`, so it must come after `make storage`).
+
+1. `POST /api/ota` with `open3e-gateway.bin`.
+2. Wait for `pendingVerify: false` in `/api/status` (60 s).
+3. `POST /api/storage` with `storage.bin`. This wipes `points.json`, so apply
+   `points.json` again afterwards.
+
+Only one UDS client on the bus: never load `points.json` while `heating-can`
+on edge-1 is running.

+## Dependency updates
+A pull request by `renovate-bot`, or one whose change is a version or digest bump of dependencies (images, Go
+modules, Helm charts, Actions, packages), gets this review instead of a code-style one. The diff only says that a
+version changed; the review is about what changed upstream and whether it touches this repository.
+1. For each updated dependency, take the release notes between the old and the new version from the PR body
+   (Renovate puts them under "Release Notes"). If web tools are available, read the release or compare pages for
+   versions the body does not cover. Web fetch opens only the links listed in the task and links in earlier fetch or
+   search results. For a dependency without a link, search for its release page first: the package name, or the
+   upstream project a wrapper image builds, with the new version. Read the notes of every version after the old one
+   up to the new one.
+2. List what in those notes can affect this repository: breaking changes, removals and deprecations, changed
+   defaults, new required settings, fixed CVEs. Then check how this repository uses the dependency: search for the
+   flags, options, APIs, config keys or image entrypoint the notes name, and cite each use with `path:line` at the
+   head sha. A breaking change that hits a use you found is blocking. A change you checked and found unused needs
+   one line, not a finding.
+3. A digest-only update of an unchanged tag is an upstream rebuild of the same version. Say so in one line per
+   image; there are no release notes to read and nothing to check beyond CI.
+4. When no release notes are available for a version change and you cannot read them upstream, say that in one
+   line in the Summary, with the old and new version and the pages you tried. Do not list it as unverified.
+5. The Summary names every updated dependency with old → new version and the upstream changes that matter, and the
+   CI result of the head. Do not restate the diff ("the bump is mechanical and consistent"): that adds nothing.
 
 ## Efficiency
 Every tool result stays in the conversation and is paid for again on every later step, so each read costs more the
