Observer EastMesh Firmware v1.15.0-eastmesh-v2026.6.0

MeshCore EastMesh Observer

EastMesh observer-eastmesh firmware for MeshCore boards with secure MQTT uplink and optional local web management, based on MeshCore firmware v1.15.0.

This release updates Observer firmware with the latest upstream MeshCore dev changes plus EastMesh web panel, MQTT, radio, and board support fixes.

What's Changed

• Added configurable custom MQTT broker support alongside the curated EastMesh and LetsMesh endpoints.
• Added Station G3 ESP32 Observer firmware targets.
• Added flood.max.unscoped so unscoped flood packets can use a separate hop limit from scoped flood traffic.
• Preserved web panel sessions across Wi-Fi reconnects.
• Hardened OTA startup from the local web panel and existing Wi-Fi connections.
• Hardened LilyGo T-Beam 1W radio setup.
• Restored the missing SX126x register patch.
• Merged upstream MeshCore dev updates, including sensor handling, RAK4631 BME680/BSEC support, documentation refreshes, and board/platform fixes.

Breaking Changes

None.

Notes

• eastmesh-au remains the recommended MQTT endpoint once mqtt.iata is configured.
• Custom MQTT is available for private broker deployments.
• For maximum heap headroom on busy observers, use the web panel for setup and troubleshooting, then disable it with set web off.
• Browsers may still require accepting the self-signed certificate warning on first HTTPS access.
• flood.max.unscoped defaults to 64; lower it only if you want to limit how far unscoped flood traffic repeats.
• If using LilyGo T-Beam 1W fan controls after upgrading, re-save your preferred fan settings if needed.
