/* Openhab hacks */
* if '''the mqtt broker binding doesn't start''', and the log shows two entries for mqtt brokers, check ''/var/lib/openhab2/config/org/openhab/mqtt.config'' for double entries (or other files that configure another broker in that directory), and remove those files
* if '''there are no channels created for a binding''', then make sure the binding didn't fail with an earlier instance which is still present in the system. Delete the bindings "Thing" and re-add, thi should make things work.
=== OpenHAB 2.3-- ===
* the isy binding now wants the following before it can start (in the OH console "ssh -p 8101 openhab@localhost" )
feature:install openhab-httpclient
feature:install esh-io-transport-upnp
* for z-wave, before adding the jar to addon/, add
feature:install openhab-transport-serial
