You take it apart, and there are the rx, tx 3.3v, gnd, and the gpio0 port and a usb rs232 adapter and ESPHome-Flasher for gpio0 to gnd.

Then you have to save him with the tasomizer in front of him. and you need a usb rs232 adapter that is 3.3v because the esp07 will be destroyed.

srv too gnd

Hello, I also created a yaml file for my SMX-ll 3.6 inverter and loaded the firmware into the data logger, which can be integrated into homeassistans. to do.
