How to update OpenEnergyMonitor EmonESP

Open update page ↗

Read the release notes first — firmware changes can require re-doing your config or calibration.
Use the project's own installer where it has one: a web flasher over USB, or an over-the-air update in its web UI.
Otherwise build or download the binary for your exact board from the releases page — the wrong board file will not boot.
Keep the previous firmware image and your config backed up so you can roll back.

Always install releases from the project itself. Firmwarely links out; it never hosts downloads.
