M-Bus (Meter-Bus) library and examples

[Acla]

Good morning, I am reading different meters by mbus communication, I have managed to read them following the tutorial by the port ('/ dev / RS232'). Would it be possible to read such data via Ethernet? I have a 4g router that has the possibility to read and transmit RS485 and RS232, it would be very useful to be able to install the router on the different counters and be able to read it all over Ethernet.

Good afternoon, I have a system of Zenner meters connected via an adapter to RS-485. I have a Schneider HomeLink LS100100 V1. If I connect a USB-RS485 adapter to the USB port, it communicates fine with the MBUS meters, but if I try connecting it to the RS485 port, it doesn’t work. The port opens, but it gives an error when scanning—it doesn’t detect anything—and it gives an error when sending or receiving frames. The same thing happens when I try to retrieve data one by one using their individual addresses.

Did you change the port name in the script accordingly?

Did you change the port name in the script accordingly?

this is my script:
require('mbus')
-
res,err= mbus.init('/dev/RS485-1', 2400

log (res,err)

--scan from range 0 to 5 (inclusive)

res1,err = mbus.scan(0, 100)
--save result to Logs tab

log(res1,err)

-- read all data from device 26

res2, er = mbus.getdata(26)
log ( res2,er)

-- read ok
if res2 then
  log(res2)
-- read failed
else
  log('[mbus] failed to read data from short address ' .. 26 .. ' ' .. tostring(err))
end

Try /dev/RS485 instead of /dev/RS485-1
