    I accidentally bought a WiFi rather than Zigbee human presence sensor - 5.8GHz microwave

    Contains the WBR3 module
    Do we think this is flashable and supported with OpenBK?

    Board model number - JYSJ_540_D01

    WiFi human presence sensor with exposed circuit board and accessories on a table. Electronic module with WBR3 chip on JYSJ_540_D01 board. WiFi presence sensor module with RX, TX, OUT, GND, VCC labels.
