What a cool project! If only I actually needed a doorbell... ;) I would however LOVE to have a blueprint for a DIY "smart" door lock (like https://nuki.io/ https://nuki.io/, but with FOSS firm- and software) available, yet a recent web search for such a thing did not yield results. If I did overlook something, please let me know!
