I have several stations. Raspberry pi 5 is the Master. Each station has 2 waveshare rtu ch32 relay controllers. I had one station working with regular wifi. I went to convert to Lora and I can not get the HRI-4851 to talk to both controllers. On station 2, the 2 controllers, address 20 and address 21, mirror each other even though they have unique modbus addresses. Initially I thought the master would be a gateway and the others would communicate as long as they were the same group and key. The distance is approximately 100 yards to station 3 and 250 yards to station 3. I want to add another 7 or 8 stations if I can get them to cooperate.
