Paulus Schoutsen, on Home Assistant’s blog:
Logitech has decided to remove a widely used local API of their Logitech Harmony hub. We’ve been tracking the story here. This has caused a lot of commotion among our users, and users of other smart home solutions, that integrated with the Logitech Harmony hub and all of a sudden were surprised with a broken smart home. Not a nice way to start the already busy holiday season!
Unfortunately, this means that without rolling back the firmware of my Harmony Hub, my TV’s, AV receiver’s, and Apple TV’s HomeKit integration is broken.
