New Hardware Interfaces

New to the community and cannot wait to do some projects. I am really appreciating the example hardwareInterfaces that come with the install and am currently writing my own for the services I have. I am wondering if there are other undocumented interfaces or collections people have that would be shareable?

I’ve got some. For example a rotary encoder for the pi and one for kodi. https://github.com/Carsten87/object/tree/TECO_mergeOH/hardwareInterfaces

Don’t know if you’ve found it already but here is some documentation: https://github.com/openhybrid/documentation/blob/master/10_For_Developers/01_Hardware_Interfaces.md
