getting unknown for sensor data

[computerbank]

I was wondering if you could help me. Here are my settingl;

Baud rate:19200
ID : i have tried 1 and 0
Transfer Protocol: Modbus TCP

I have a flexbooss 21. I have connect the wire to 485 b to b and 485 a to a. plus ground. Im using a waveshare rs232/485/422 to poe eth

THanks

I can try, just keep in mind that I've only tested this on 12kPV and an 18kPV -- I'm not sure if the registers for the flexboxx are identical.

Have you confirmed you have working communication via some other method? I use modpoll on Mac. Or there are phone apps.

./modpoll -0 -r 7 -c 3 -1 -t 3 10.x.x.x   <----------REPLACE WITH YOUR IP

Protocol configuration: MODBUS/TCP, FC4
Slave configuration...: address = 1, start reference = 7 (PDU), count = 3
Communication.........: 10.x.x.x, port 502, t/o 1.00 s, poll rate 1000 ms
Data type.............: 16-bit register, input register table

-- Polling slave...
[7]: 123
[8]: 456
[9]: 789

This should show you the three PV channels' power in watts

@computerbank I'm interested to see if you get this working. I also have two FlexBoss21 and a GridBoss and would rather use this than give them access to the internet.

@apetrycki from what I've read, the FlexBoss21 will work with this.
