Solutions

1. Verify the Bryant Evolution thermostat system is powered on and reachable on the network/serial connection.
2. Check that the configured filename/device path for the Evolution connection is correct and accessible.
3. Confirm the device is responsive, then reload the integration; setup will retry automatically.

Example fix

The Bryant Evolution system cannot be reached or its serial device file is missing. Confirm the equipment is connected and powered and that the serial device path in the configuration exists, then reload the integration; setup retries automatically.
