I put up a post about how Homebridge Buddy has a ground up rewrite coming soon (currently in Alpha, hopefully Beta in a few days) and there have been a handful of people asking to Beta test that new plugin that appear to be newer users. I just wanted to say that until there's a stable release of HomeKit Bridge that you can still use Homebridge Buddy to use with HomeKit until the new plugin is ready for prime time. While HBB doesn't expose every possible HomeKit device type it does work well for most things you might want to use your new HomePod for in regards to Home Automation.
This is just a public service announcement . I expect HomeKit Bridge to be out of Beta by May at the latest (but should be relatively stable in the coming weeks honestly) so until then HBB is still around (and will be after HomeKit Bridge is released in full as well).
