I did not publish this on HACS on purpose. It was for my internal use only and it was working for my use case. Since I don't use these thermostats anymore I will not fix any bugs or implement new/missing features. Use the code at your own risk. Pull requests are of course still welcome.

This is a custom component for Home Assistant to control Max! eQ-3 products over a CUL device. It is possible to use a CUL connected as a serial device (via USB) or through a telnet connection.

Installation of this component is possible through HACS or by copying the directory manually into the custom_components directory of Home Assistant.
