This is a custom component to allow control of Ooler Sleep System devices in Home Assistant using bluetooth.

In Apple Home through HomeKit Bridge

What HomeKit Bridge makes of each kind of entity this integration creates, read from its source code. A device only gets the ones that apply to it.

Entity	Shows up as	Note
`switch`	Switch or outlet
`climate`	Thermostat
`sensor`	Sensor (temperature, humidity, air quality…)
`select`	Mode picker (as switches)

How it connects

Talks to the device on your network, and the device tells Home Assistant the moment something changes.

Devices listed in its README

Ooler Sleep System (all models with BLE GATT interface)

Limitations from the README

One Bluetooth connection at a time. The Ooler only supports a single BLE connection. If the Ooler app is connected, HA cannot connect (and vice versa). Use the Bluetooth Connection switch to disconnect from HA when you need the app.
ESP32 proxy connection slots. Each Ooler uses 4 BLE notification slots. ESPHome proxies provide 12 slots (vs 9 for raw ESP-IDF). If you have multiple BLE devices on one proxy, you may run into slot limits.
No Wi-Fi or cloud support. The Ooler communicates only via Bluetooth. The device must be within BLE range of your HA server or an ESPHome Bluetooth proxy.

In ReReHome

Whatever HomeKit Bridge shares reaches Apple Home as normal HomeKit accessories behind your Home Assistant bridge, so ReReHome shows and controls them like any other.

Bridges get their own settings page listing the accessories behind them.
