Hello,

first of all, great piece of software, just what I needed. I started using mbusd to read out my Eastron SDM630 meter, which worked perfectly. Mbusd runs on a raspberry pi 1 B+, RS485 connection via a USB adapter, data are processed by an iobroker installation using modbus adapter.

However, I have now changed this setup on the mbusd side to communicate with my solar inverter instead and let the Eastron talk directly to the inverter (the latter works flawlessly). No errors are logged, however mbusd now keeps disconnecting almost instantly permanently. Values get through in either direction sporadically, i.e. both holding and input registers are in principle working.

I suspect that the inverter is responsible for the problems. However, is there any setting that I could adapt to maintain the connection? Here is a part of the log (verbose level 9):

19 Nov 2024 07:32:00 tty: response timeout
So the inverter didn't response. Try to increase the timeout option.
Also make sure, that timeout in the TCP master is higher then this timeout * (retries + 1) so you will not get timeout on TCP before mbusd "finish" the reading.
