    Hi all,

    First time experimenting with "non ESP chips" and after some tinkering i have the 3 way switch working. This "Ali" switch has no markings except WIFI-W6B on the "top" board and has a Tuya T34 chip (BK7231N).

    Two-part image showing packaging and the back of a switch on a wooden surface. Close-up of a blue printed circuit board with electronic components. Photo of an electronic board with two large relays and other components on a wooden background. Printed circuit board labeled WIFI-W6B connected to wires. Close-up of a circuit board with a Tuya chip and other electronic components. Close-up of a circuit board with a T34 chip and connected wires at labeled pads: ground, n.c., vcc 3V3, Rxd, Txd. Three-way switch and box on a wooden floor.

    The pads are easy accessibele for flashing. Had to lower the baudrate to 115200, problably an error at my side. The config extract did not work, after some puzzle i found this to be working.

    the config:

    You are very lucky to get T34 device with programming pads. Some of T34 switches are coming without them.
