The **Bryant Evolution** {% term integration %} lets you control Bryant Evolution HVAC systems.

## Prerequisites

- It requires that a System Access Module be connected to the HVAC system (for example, a Bryant SYSTXBBRCT01).

To install:

1. Connect the System Access Module to the device running Home Assistant, for example, by using an RS-232-to-USB adapter.
2. Install the Bryant Evolution integration in Home Assistant, passing the name of the serial port to which the device is connected (for example, `/dev/ttyUSB0`)
