Hello!
This user prepared a custom firmware for this gateway a few months ago. I uploaded it to the gateway following the instructions, and everything works fine in HA. If anyone needs help, I’ll open a thread. You need a CP2102 USB to TTL and a small connector to solder onto some pins on the board to connect it to the PC. It’s very simple. Complete instructions and wiring: GitHub - jasperw1996/ambd_sdk_GW018-DM: Release SDK for AmebaD
