This adapter is designed to connect an eBus compatible boiler to any TTL port (TTL-USB, ESP8266, ESP32, Arduino, etc).
Same size as popular RS485-TTL module for more compatibility.
As a software part, you can use ebusd with different connection types:
- TTL-UART - you need converter that doesn't buffer too much data (CP2102 or FTDI based (like FT232)) 👍
- ESP8266 / ESP32 enhanced ebusd protocol using ebusd-esp firmware (only Wi-Fi connection now) 🎉
- Raspberry Pi internal UART port can be used with some preparations,
but I recommend ttyebus kernel module which is with the lowest latency possible 🚀 - ser2net compatible firmware (ESPEasy, ESP-Link, ESPHome, Tasmota, etc) or hardware converter with some restrictions (Receive - OK; Transmit - may be errors) 🤔
Also available HA integration between ebusd daemon and Home Assistant 🏚
- iBOM page 🌍
- Gerber zip 🗂
