Choosing Between Bluetooth and Bluetooth Low Energy for Room-Assistant: A Guide

If you're using Home Assistant, specifically with a Raspberry Pi Zero W, you may be wondering whether to use Bluetooth (Bluetooth Classic) or Bluetooth Low Energy (BLE) for your room-assistant setup. This article aims to provide an in-depth comparison of both options to help you make an informed decision.

The Problem with Bluetooth

Bluetooth uses the 2.4 GHz band, which is also occupied by Wi-Fi and Zigbee. This leads to interference between the three technologies, resulting in slower response times and instability. With BLE, however, you can experience faster response times and more stability due to reduced interference.

BLE: The Better Option for Room-Assistant

Bluetooth Low Energy (BLE) is a better option for room-assistant because it uses a different band than Wi-Fi and Zigbee. This means less interference and improved performance. BLE also offers other benefits, such as increased range and reduced power consumption.

Room-Assistant Clusters: The Power of Collaboration

When multiple instances of room-assistant work together, they can triangulate your position based on signal strengths and inform Home Assistant of your exact location. Room-assistant clusters are a powerful tool that allows the application to track devices on a room-by-room basis.

Using Room-Assistant with Home Assistant OS on Raspberry Pi Zero W

If you're already running Home Assistant OS on a Raspberry Pi Zero W, you can make use of its available radios to connect your room-assistant instances. There is also a room-assistant add-on available for Home Assistant that allows you to run multiple instances on the same network.

In conclusion, BLE is the better option for room-assistant due to its reduced interference and improved performance. Room-assistant clusters are a powerful tool that allows the application to track devices on a room-by-room basis. By using BLE and room-assistant clusters with Home Assistant OS on Raspberry Pi Zero W, you can create a robust and efficient home automation system.
