⚠️ This is a beta release — please report issues at https://github.com/arjenhiemstra/ithowifi/issues
New Features
- OTA firmware updates — Install firmware directly from the web UI with version dropdown, progress bar, timeout detection, and error feedback. Supports stable and beta versions. Also available via MQTT, REST API, and Home Assistant.
- RF standalone mode — Control Itho devices without I2C connection (e.g. HRU 400) using RF only. Status data received wirelessly via 31DA/31D9 messages. Includes wizard setup with guided RF join flow.
- ArduinoOTA removed — Replaced by HTTP-based OTA. Saves ~1.5KB RAM and ~6KB flash.
