We have an ESP32 based communication device that has been designed with:
1. USB 2 RS232 converter for connectivity and software update
2. RS485 driver on a serial port, for Modbus communication
3. CAN driver
4. Frequency counter input (already designed)
5. MQTT support is aldready implemented in the software
6. An OLED display for debugging and status updates
We need to add Modbus support to this device, where the software must be preparred to inteface to 3 different types of appliances over Modbus.
Data recorded from these devices must be reported to our portal software using MQTT.
There are a number of additional features and request defined in the attached document.
If this project is successfull we are looking for additional functionality to be implemented as dedicated proejct, following this design.
