    A smart switch with an ESP8285 directly soldered to the PCB

    Overal quality of the switch seems very cheap, I can see only the fusible resistor protection of the input, but still, it should do the job. Have you managed to get the Tasmota template for that one?

    I just had the same device and realized... it has no LDO! BP2525 provides 3.3V directly, and relay is also for 3.3V. Interesting. @divadiow

    doesn't it always have both, if TuyaMCU it'll be different version

    Is it? I didn't look there much, but at some point I assumed that for non-TuyaMCU devices, it will have only a single version string. I may be wrong.
