This can be done in two ways: the simple method and the more complex method.

Simple method

1. In “Home Assistant”, go to “Settings”.
2. Click on “Automations scenes”.
3. Click “CREATE AUTOMATION” and then click “Create new automation” again.
4. Click “ADD TRIGGER”. Click “Device”.
5. Find the relevant device and select it.
6. As the “Trigger”, select “Device x Reboot is pressed”.
7. Click “ADD ACTION”. Click “Device”.
8. Find the relevant device and select it.
9. As the “Action”, select “Device x …” and then the output you want to be active immediately after startup.
10. Click “SAVE”.
11. The relevant output will now be turned on by “Home Assistant” immediately after the device starts up. Please note that “Home Assistant” must be active before the device is switched on. If you want the device to always control certain outputs at startup independently of “Home Assistant”, follow the complex method.

Complex method

1. First, follow the complex method for adding a device to “Home Assistant”.
2. Go to the YAML file of the relevant device.
3. Under the desired output that should be active immediately at startup, add the following code: “restore_mode: ALWAYS_ON”. See here an example where output 1 will turn on immediately after the device starts up.
   • – platform: gpio

     pin: GPIO0

     name: “Output 1”

     restore_mode: ALWAYS_ON
4. Click “SAVE”.
5. Now click “INSTALL” and install the firmware using your preferred method.
6. The relevant output will now become active immediately after the device starts up, independently of “Home Assistant”.

1. Turn off the Wi-Fi that the RSx is connected to. After one minute, the RSx will appear as an access point and the green LED will start flashing.
2. Connect your laptop or smartphone to the Wi-Fi Access point
   “Gevako-RSx Fallback Hotspot”.
3. Go to “192.168.4.1”.
4. Select your desired 2.4 GHz Wi-Fi SSID and enter the
   corresponding password. Click “Save”.
5. Wait 30 seconds. Restart the RSx by switching off the power supply.
6. Wait 10 seconds after the red LED has turned off. Switch the power supply of the RSx back on.
7. The RS6 will now attempt to connect to
   Wi-Fi. Once the green LED is lit, the connection is established.
8. You can now turn the Wi-Fi back on.

If you need to reset your Gevako device or clear its Wi-Fi / Thread credentials, you can perform a factory reset using either the physical button or the Home Assistant interface.

Note: Ensure your Gevako device is running the latest stable firmware (updated via USB-C or OTA).

Method 1: Using the Physical Button

1. Press and hold the BOOT button for at least 10 seconds.
2. After 2 seconds, the green LED will begin to flash rapidly.
3. Continue holding the button. After 10 seconds, the LED will turn off, indicating that the factory reset has been initiated.
4. Your Wi-Fi / Thread credentials will be cleared, and the device will be ready to be re-added to your network.

Method 2: Via the Home Assistant UI

1. Navigate to Home Assistant > Settings > Devices & services.
2. Click on “X devices” under the ESPHome integration.
3. Select the specific Gevako device you wish to reset.
4. Locate and click the “Factory Reset” button.
5. Your Wi-Fi / Thread credentials will be cleared, and the device will be ready to be re-added to your network.

Yes, you can. Use Gevako Installer and update the device to the desired firmware option.
