Boot button status check and factory reset

The boot button on your CAST PRO-1 does two things while the device is running, depending on how long you hold it:

Hold for What happens
About 3 seconds Status check. The onboard LEDs show the connection status, then run a component check.
10 seconds Factory reset. Erases your Wi-Fi details and settings, and the setup hotspot comes back.

The boot button is the second recessed button from the left, next to reset. Press it with a pin or a small screwdriver.

Status check

Use this to see whether your CAST PRO-1 is on your network and talking to Home Assistant, without opening an app.

1. With the CAST PRO-1 plugged in, hold the boot button for about 3 seconds, then let go.

2. Watch the onboard LEDs. They flash one color to show the connection status:

Color What it means
Yellow No network connection. Check your Wi-Fi details or Ethernet cable.
Green On your network, but not connected to Home Assistant.
Blue Connected to Home Assistant.

3. The LEDs then flash green once more. That's the component check passing.

Factory reset

A factory reset erases your Wi-Fi details and settings, so you'll set your CAST PRO-1 up again afterward.

Unplug the Ethernet cable first

Your CAST PRO-1 doesn't broadcast its hotspot while an Ethernet cable is connected, so take the cable out before you start.

1. With the CAST PRO-1 plugged in, hold the boot button for 10 seconds, then let go.

2. The CAST PRO-1 restarts and broadcasts its hotspot again.

3. In Home Assistant, delete the old CAST PRO-1 from the ESPHome integration. Open its device page, select the three dots menu, then Delete.

Open your Home Assistant instance and show an integration.

4. Follow the Getting Started guide to connect your CAST PRO-1 to your network, then add it to Home Assistant again.

Still not broadcasting a hotspot?

If your CAST PRO-1 won't broadcast its hotspot after a factory reset, reflash it to restore the factory firmware.
