## AI overview

The Open Home Foundation describes how recent Home Assistant and ESPHome releases use generic proxying to connect older, offline devices to modern smart homes. Small microcontrollers can act as bridges for infrared, radio frequency, and serial communication, alongside existing Bluetooth and Z-Wave proxies, allowing devices such as older receivers and air conditioners to be controlled over the home network.

## Source excerpt

Every smart home has them: the older devices that still work perfectly well but no longer fit neatly into a modern setup. Instead of letting them gather dust in a drawer, the Open Home Foundation's projects can help you bring them back into the fold. Here's how a little proxying can give your beloved old gear a new lease of life, and keep your smart home that bit more sustainable.
