I have seen in pieces of code such as [https://github.com/robertraaijmakers/nl.ithodaalderop/blob/master/app.json#L79](https://github.com/robertraaijmakers/nl.ithodaalderop/blob/master/app.json#L79)

That besides the documented ASK, FSK and GFSK modulation, we can also choose 2-FSK.  
So all in all, what modulations does homey support really?
