eBUS Adapter Stick C6 - tiny version of eBUS Adapter Shield
eBUS Adapter Stick C6 is a reduced size version of previous highly demanded eBUS Adapter Shields and provides an interface to a 2-wire eBUS with galvanic isolation for enabling communication with an eBUS enabled heating, ventilation or solar system.
With a size of 42 x 16 mm it is way smaller than the previous Shield versions, but still supports an USR-ES1 module being plugged onto it for having Ethernet access.
Even better, with the upcoming firmware version for the ESP32-C6, it automatically scans the heating components and makes all data available via MQTT to e.g. Home Assistant with auto discovery of entities.
eBUS Adapter Stick C6 provides an interface to a 2-wire eBUS with galvanic isolation and thus enables communication with an eBUS enabled heating, ventilation or solar system.
It is the smaller USB-stick like version of the previous adapter v5 sharing the very same technology with even smaller footprint (42x16mm), pluggable eBUS connection, on-board WIFI by using an ESP32-C6, support for USR-ES1 Ethernet module, and including a white enclosure.
The v5 version of this interface was born to life early 2023 after several rounds of prototyping and is already in use by thousands of people. Since then, multiple design optimizations were performed including an eFuse for over voltage+current protection, and USB-C connection starting with the C6 version.
Features
Full galvanic isolation with zero power drawn from eBUS (class 0 as of eBUS specification)
