| 4-20mA_Lora📡<-->📡Lora_Modbus | ☐ | ||
| 0-10V_Lora📡<-->📡Lora_Modbus | ☐ |
📝Note:
(*) Scenarios: Node A read value from sensor (I2C, modbus, 4-20mA, 0-10V, one-wire), and send to node B.
Node B is modbus slave, simulation sensor, update value in register each time recieve signal from node A.
We can use PLC or another device read value modbus RTU from node B. It is same read direct sensor, but there is a small delay.
Regarding One-Wire sensors, we will wait for support from RAK team in Q3-2023.
Currently, because of RUI3 limitations, there is no official library for this communication standard from Rakwireless.
