The hub now serves LoRa and the new ESP-NOW "Lite" transmitters at the same time, and ships a fully redesigned OLED + LED experience. Recommended for every hub; required to pair the new Lite transmitters.
What's new
- Universal hub. A concurrent ESP-NOW receive path runs alongside LoRa and fills the same registry — one hub handles a mixed LoRa + Lite fleet. Transport is auto-detected at pairing; there is no selector to set.
- Redesigned OLED. Per-tank layout: name + signal bars, a cylinder with wavy water and level ticks, droplet + litres, and battery + last-update. Cloud-optional fix — no more stuck "NOT LINKED" when running without the cloud.
- WS2812 LED ring. Boot animation, gauge that follows the OLED's current tank (8- and 24-LED modes), live strip-mode switching, and a WiFi LED that turns green when connected.
- ESP32-S3 SuperMini pin-map updates for the S3 hub build.
