I have seen archived posts on these BLE controllers model: SBMC01. I have a solution for this. It’s pretty simple:
Step 1: Install the Home Decorators App
Step 2: Pair and Calibrate blind(s)
Step 3: Find the MAC Address of your device and the Alias
Step 4: Use a Raspberry PI and spoof/change your BLE MAC Address on the device to match the MAC Address of the phone you used to pair.
Step 5: Install BluetoothCTL (Bluez) on the Pi.
Step 6: Clone the Alias to the phone you used to pair the blinds.
Step 7: Use BluetoothCTL to pair your Pi with the Blinds.
Step 8: You may now use gatttool to send commands.
Commands are:
–char-read -a 0x0047 (Read Time)
–char-write-req --handle=0x0021 --value=02 (Identify Shade)
–char-write-req --handle=0x23 --value=00 (Shade Down)
–char-write-req --handle=0x23 --value=01 (Shade Up)
–char-write-req --handle=0x23 --value=04 (Favorite Position or Stop)
Now that you have this in place you can use Python or the Exec node from NodeRed to control these using MQTT protocol to and from HomeBridge/HomeAssistant.
