Wallbox Gateway v2.3.0

Significant release combining first community contributions with new
visibility features.

🙏 First community contributions — thanks @benvanmierloo!

Two excellent additions in #1:

• BLE SMP pairing for Wallbox firmware ≥ 6.11.26. Newer charger firmware
  requires an encrypted BLE link before allowing notifications. The gateway
  now tries plain registerForNotify first (backwards-compatible with
  older firmware) and falls back to SMP passkey pairing using the
  configured BAPI PIN. Unlocks compatibility for everyone on the newer
  firmware. Tested on FW 6.11.16 (no fallback needed) so existing users
  see no change.
• Telnet log server on port 23. All Serial output is streamed to up
  to two LAN telnet clients, advertised via mDNS. Zero overhead when no
  client is connected. Connect with telnet wallbox-gw.local from any
  Linux/Mac/Windows machine on the LAN — finally, remote-debug your
  gateway without a USB cable.

☀️ Solar savings on the stats tiles

If you charge in Eco Smart mode (solar-aware), the gateway now shows
how much money you saved by using your own solar versus the grid
tariff. Visible as a yellow "saved $X" sub-line under the Week / Month
cost tiles on /sessions. Configurable green rate (default $0 = free
solar; set to your feed-in tariff to see opportunity cost).

🔔 Notifications: Home-Assistant route

Browser push notifications can't work over plain HTTP (browser security
restriction). The new Notifications panel (Settings → Charger → 🔔
Notifications) recognises this and instead gives you a ready-to-paste
Home Assistant automation snippet that delivers proper push
notifications via the HA Companion app, using our existing
sensor.wallbox_pulsar_max_status MQTT entity.

⚡ Faster page reveal

Page reveal now triggers on DOMContentLoaded instead of window.load.
On a busy gateway (e.g. weak BLE signal causing the firmware to fight
for radio time), pages now appear in well under a second rather than
waiting for every CSS/JS asset to fully load.

Install

OTA from any v2.x: http://wallbox-gw.local/ota → upload the .bin.
Fresh install: see v2.1.0 README.

Coming next

v2.4 — Pulsar Plus compatibility is in active prep. The transport
layer differs (separate RX/TX characteristics, OS-level pairing
required) but the BAPI protocol overlaps with Pulsar MAX. Looking for
Pulsar Plus owners willing to flash and share scan/telnet logs — open
an issue if interested.
