I just tried to install the Modbus binding Snapshot Version 1.11. in my running OH2 sytem (V 2.1.0) and copied the JAR file into the addons directory.
After a restart I get the following output:
openhab> bundle:list | grep Modbus 208 | Active | 80 | 22.214.171.124708050109 | openHAB ModbusTCP Master Binding 219 | Active | 80 | 1.10.0 | openHAB ModbusTCP Master Binding
My system seems to work as always - no strange errors in the log.
Is it somehow possible to install two versions in parallel?? How can I get rid of this problem? Or is there nothing to worry about?
