    Works great as Bluetooth proxy for Home Assistant

    I ordered this at the suggestion of the ESPHome page about Home Assistant Bluetooth proxies. It took moments to get setup and is working perfectly. The design is visually appealing and it’s really small. These tow attributes make for a device I’m happy to use as-is… no case creation needed.

    Great little devices

    I'm using them as bluetooth proxies with Home Assistant currently, but have found them to be so awesome I intend to get into other possibilities with them.
