Experimental custom firmware for SONOFF ZBMINIR2 with support for Zigbee bindings.
Check out the wiki for instructions on building the firmware and flashing. Join Discord if you have any feedback or questions about getting it up and running or adapting it to your use case.
- This firmware is experimental and currently only implements functionality to send Zigbee commands to bound devices upon triggering the external switch.
- Flashing the ZBMINIR2 requires disassembling the device (difficulty: very easy) and attaching a SWD adapter to its test points (difficulty: medium). This might require soldering. Future updates can be installed over-the-air.
- You cannot revert to original firmware because the device is locked down and the (original) firmware is encrypted with an unknown cryptographic key. Unlocking the device will also wipe the key.
- Support for bindings to directly toggle a Zigbee device (e.g. lightbulb) - works even when the coordinator is unavailable.
- Updates can be installed over-the-air
- 'Factory reset' by toggling the external switch ~5 times within 5 seconds.
- Supports a simple on/off switch only (ie. no pulse switch).
