I’d like to communicate directly with a Wireless AC Current Detection Sensor, without using a modem or other box. Writing TCP/IP network code is not a problem for me. The Highlights list for this product says “Open Communication Protocol for Easy Software Integgration”. Is documentation on this protocol available?
You will need the Ethernet modem to convert wireless data into TCP/IP packet.
Are details on the wireless protocol between the sensor and the modem available?
Sure. we use Digimesh radio modules.
This product is slightly different. However if you have power available at the sensor location I think it could work for you:
This device communicates current readings over MQTT which is simple to implement.
