Update from eHome
If you have the previous model eHome (not HA version), you can simply update the firmware to turn it to be eHome HA. Just click "..." > "Update to eHome HA" and proceed with the firmware update.
During the firmware update, please monitor the LED indicator status. If the LED starts flashing intermittently (flashing four times, pausing once, then repeating), it means the device has been reset—this is expected after updating to the HA version.
At this point, you can either terminate the update process by closing the app on your phone or simply wait until a failure message appears.
Once done, set up the device again as a new product, and you will gain access to the MQTT for HA feature.

Ensure the device LED is flashing intermittently (quickly flashes 4 times then pauses once). If not, press and hold the reset button for 5s until the device resets.
4. PREPARE SETUP
Turn on Bluetooth on phone. Click "+" >"Add Device" > "Add a New Device" in the App and select the product. Keep device, phone and router closer.
5. SET UP DEVICE
Select a WiFi network for the device and enter the correct password to proceed (device LED will turn off). Then assign device to a room and name it.
NOTE: During setup, your phone does not need to be connected to the same WiFi network. You can even stay on the cellular network if you prefer.
6. CREATE AN RF PANEL
Click the "+" icon in the top-right corner and select an RF type (for instance curtain). To control your RF device using both the app and Home Assistant, select " Add for HA " (recommended). Follow the wizard to learn the RF remote and test it with the controls. Then save your settings and proceed.
IMPORTANT : If you don't see the MQTT connection setting in the menu, it means you're using the eHome model, not eHome HA. However, you can easily upgrade the firmware to convert it to eHome HA. Please refer to <a href="https://kb.linknlink.com/kb/smart-home-devices/ehome-ha/update-from-ehome" rel="noopener noreferrer" target="_blank">Update from eHome</a>

Once MQTT is connected, the added RF device will automatically appear in your Home Assistant, with the available buttons synced and ready for use. You can now use the RF device in HA for complete local automations.
NOTE : Once the MQTT connection is set up, any newly added RF devices will be automatically synced to Home Assistant without the need for additional configuration.
