## From the README

> This integration monitors the inputs and outputs of the devices connected to a C.M.I. from Technische Alternative. It creates a separate (binary) sensor for each input and output which displays the current values.
>
> Note The loading time of the integration is extended by one minute per configured node on the C.M.I. to avoid triggering the rate limit. The same applies to the setup process
