Communication with a smart home system is definitely not required. The smart home system should control the charger not the car. The bsoc of the Twike is not relevant for how much you need to charge over night. It is the next day planned usage that determines de amount that needs to be charged overnight. That overnight charge amount will be user input in your domatica system. Bidirectional charging with your Twike is an expensive solution. A home battery is 4 cent per kWh. The price per kWh on the Twike will be 10 times more expensive.
