IR Blaster downloads

Firmware for IR Blaster nodes and the ESP32 hub, and the IR code catalog behind the hub’s Add device page. Your hub checks here for updates on its own; this page is for looking things up or installing by hand.

Firmware

The current image for each chip. Older images are removed when a new one is published.

manifest.json

Nodes

One image per chip runs on every board with that chip.

Loading firmware…

Hub

For the dedicated ESP32 hub.

Loading firmware…

Turn on JavaScript to list the firmware here, or read firmware/manifest.json directly; each entry’s file is in the firmware/ folder.

You rarely need these by hand. The hub’s web page reads this site, flags nodes running older firmware and installs the update for you.

These are update images. Install one from a node’s own page (Settings → Firmware update) or from the hub (Settings → Update hub firmware…). For a board that won’t start, or a blank one, use the recovery tool. Check a download against its SHA-256 with sha256sum (Linux), shasum -a 256 (macOS) or certutil -hashfile <file> SHA256 (Windows).

Recovery tool

Reinstalls the firmware over USB, for a board that won’t start or a blank one.

All releases

Checking for the latest version…

Plug the board in with a USB data cable, open the app, click Connect, then Recover. It downloads the current firmware from this site and keeps the board’s settings unless you ask it to erase them. Nothing to install: it is a single program. The app isn’t code-signed yet: on Windows choose More info → Run anyway; on macOS open it once, then choose Open Anyway in System Settings → Privacy & Security.

IR code catalog

Ready-made remotes, so you can add a device by brand and model instead of learning every button.
