Hello everyone,
i’m wondering if someone can recommend me something in size of sonoff basic with in/out terminals which will act as a dimmer?
I dont really need wall-switch-like dimmers as this is supposed to replace dimmer which is hidden in kitchen kabinet. But mainly i need input output terminals and ideally tasmota flashable eg. MQTT ready hw.
You have to solder Rx, TX and IO0. Then you can either solder the 3.3V and GND or use you external power supply. Never use 5V on the 3.3V pin.
This will kill your device.
There are some videos on youtube. Just search for tasmota and magichome
but sadly I have no luck to get to flash mode for some reason, regarding board version I have everything connected as it should be.
Crappy debugging ;/
edit, well one of my usb-uart is obviously dead, flashed with another one
gpio0 sets device to flash mode only if shorted to ground during boot, so it’s pretty ok to use it.
for example ESP-01S is using gpio0 without any issues.
but gpio1/3 rx/tx is good idea indeed. Haven’t thought about those …
