A attempt to write down the protocol of the eQ3 / ELV MAX! Cube
Home Assistant integration for eQ-3 MAX! heating thermostats, wall thermostats and window contacts via a CUL/CUNO (or a MAX! Cube flashed with a-culfw) – fully local, replaces the discontinued eQ-3 software.
CULfw v1.6.7 with disabled duty cycle restrictions
eQ-3 MAX! (radiator and wall thermostats, window contacts, eco buttons) directly in Home Assistant via a CUL stick or a flashed MAX! Cube – no Homegear.
Patched maxcube library for Home Assistant: persistent TCP connection, RX thread, instant push notifications for MAX! Cube devices (thermostats, window sensors)
