Home Assistant DIY, ESPhome, creating a Bluetooth proxy !
My Home Assistant(HA) server setup is virtualized with Linux KVM and needed a solution handling Bluetooth since the used Mac Mini just had a PCI connected one. Please note this is just a post due to problem with indexing ! Check the "real" one below from February 18, 2026 !! HA recommends to use a Bluetooth proxy(BTP) quote "since Linux kernel updates have previously broken Bluetooth functionality and Bluetooth driver support Linux generally falls behind other operating systems for newer adapters. A Bluetooth proxy is particularly interesting to users who virtualize their instance, where the USB pass-through may cause additional problems". . . . .
