cgllc.gateway.s1 (Xiaomi cleargrass Bluetooth gateway)
**Device model**
cgllc.gateway.s1

**Device name**
Xiaomi cleargrass Bluetooth gateway

**Does the device require a MiCloud connection?**
Do not know
Although it might, [this GitHub issue for HASS](https://github.com/al-one/hass-xiaomi-miot/issues/368) mentions HASS is pulling the sensor data via MiCloud if I understand correctly.

**Anything special about the device?**
It's a gateway, so it determines the individual accessories paired to it.
It's used for BLE devices, mostly BLE Termohygrometers
There's BLE Termohygrometer support in Homebridge, but it's a plugin that aims to directly connect to the sensors rather than interacting with the gateway.
