    Got a different pcb than the previous comment that showed the different pads to solder to flash the firmware. I could easily flash the switch with the rx/tx/gpio0 pins accessible at the front and 5V power via the pins already present at the back. Used the same esphome config as a sonoff touch wall switch. Switch works perfectly.

    It works as described. You need to put capacitor in parallel with the lamp as described. It works also with my google home mini, so I can control it with voice. :-)

    Good product. I could install Tasmota on it. You need to connect to the pads above the chipset. The pinout is from left to right TX, RX, GND, VCC, GPIO0 (see picture attached). When you power on the device you need to connect GPIO0 to GND in order to start the programming mode. I selected "Sonoff Dual R2" in the Tasmota configuration and I see that it works without issues.

    Works very good with ESPHome (just took some effort to flash as pins are not marked). Very silent and responsive. Capacitor really small compared to T4 one. Two of them doesn't fit in normal JB setup.

    These work really well. Flashable with Tasmota. Just be careful of the pads for the headers, the solder can easily come off when removing the link cables. Best to use a solder pump and very little pressure.

    This is my second switch. The device has a modern design, good quality and works well.

    This is the pinouts on this board if anyone wants to flash with tasmota firmware. These work great and the capacitor is easy enough to fit.

    Works just fine. Easy integration with Google Home.
