Hello,
in falshed my Wemos with this software: GitHub - john30/ebusd-esp: Firmware for ESP8266 allowing eBUS communication for ebusd (https://github.com/john30/ebusd)
after that i changed to
mixed software D1 + TX1 D4
soldering RX → D4 and TX → D1.
After that i connect my EBUS Adapter v2.2 → Wemos → USB → RPI4 (ebus)
I dont’t get any ebus data
My Wemos show me
ebusd connected: yes (inactive)
eBUS signal: acquired
