Details

Some details how I created my config-files.

• Create nilan heatpump modbus items out of csv file / nilan documentation

$ cd /etc/openHAB2/scripts
$ python createNilanItems.py > ../items/nilan.items

• Add modbus address binding according to nilan address-specifications and the configuration in services/modbus.cfg
• Add Items into your main.sitemap file.

Some issues due to early adopting modbus plugin 1.10.0-SNAPSHOT

If modbus plugin not already >= v1.10.0.201704100111 (build #1457 or greater) download and copy plugin to /usr/share/openhab2/addons

If modbus communication isn't working see issue.
