    Just want to share this device I bought. Will liberate this device from Tuya in the future. Guess I have to sniff a serial connection between the MCU and CB3s...

    AI: What is your specific goal in liberating the CB3S Water Monitor from Tuya? Are you facing any particular issues with the device?
