Boston Mesh has a custom batch of Washtastic boards that use the E22P module (not the standard E22). Because of that hardware difference, we built a dedicated firmware variant with the required changes documented here: commit

In the release uploads, I’ve also included the additional firmware changes needed to run the device as an MQTT Observer. This build enables packet logging via -D MESH_PACKET_LOGGING=1, set through PLATFORMIO_BUILD_FLAGS.

We need to update the bootloader on the ProMicros. Make sure to follow promicro-upgrade.md before flashing the custom firmware.

You can find all the downloads in the Releases Page.
