I had success a couple of years ago patching the Chrome binary to put my own CA Chromecast roots in there and then broadcasting my software device over mdns [0]. At that time the newer protocol wasn't implemented in Chrome yet so the furthest I got was appearing in the device list. But now it is implemented [1], so maybe I should revisit. Of course this isn't a general solution since it requires patching the binary instead of having some other way to use custom keys (they compile them into Chrome today, and of course other devices are even more closed). 0 - https://github.com/thibauts/node-castv2/issues/2#issuecomment-403872299 https://github.com/thibauts/node-castv2/issues/2#issuecommen... 1 - https://bugs.chromium.org/p/chromium/issues/detail?id=809249 https://bugs.chromium.org/p/chromium/issues/detail?id=809249
