Modbus error management in openHAB

These notes apply to modbus binding version 2.x This is not a Modbus how-to, but rather a tuning guide for advanced users.

But to begin, we’ll look at how you can detect a Modbus problem using openHAB, so that you can build rules to take some action; send a warning message, put control systems into a fallback mode, or whatever.

I expect you’re doing this already, but make sure your router DHCP is set up to issue static IP addresses to to openHAB and Solaredge, or set fixed addresses in them, in case the “loss” was due to unexpected IP change.
