After few second the state change anyway but the interaction is very very slow

We are checking the Modbus driver again, possible fixes will be available in next update.

That has not gone well for me, I've now lost all my Zwave network, shall I start a new thread or is this something you know about?

Hi, please check if you have any invalid addresses in you modbus configuration. Try to create new Modbus configuration with only few addresses for which you are sure that they are correct.

We having the same problem here

we using KNX IP Routers and a TCPIP Modbus connection to a BMS System (SHE RCM)

Thru Modbus Commands we are switching KNX Groups on the other side

Whenever there is a Communication Problem to 1 of our KNX Ip Routers (no Power) as well the Communication to the Modbus also goes on error for 15sec and connect back.

It is for sure not a Network Problem we have checked with Wireshark


This is only happen after the last update before it was running normal without error on the modbus side

Did you try with any other Modbus monitor to see if you get the state?
