if you use raspberry PI , you can add a USB-RS485 adapter, connect to our modbus power energy meter. Node-red can read it , KC868-H32BS also have RS485 port, support modbus, or you can integrate by ethernet cable use MQTT protocol. so you can control relay ON/OFF and read sensor data, the logical setting just by yourself in node-red.
