I am having an issue similar to one posted in 2016.
Currently running OH 4.3.2 on a Headless Ubuntu Server VM. I also believe I am using the latest Insteon Binding - although I do not know how to find the current version info.
I have had a ton of success and all of my Insteon Modules are working great in OH. My issue is with the 2342-2 8 button mini remote. I have the device in 8 button mode. It is paired just fine to the modules it is controlling. But I would like to do a little more with the OH Rules. BUT - looking at the log something seems to be wrong. Only the top 2 buttons seem to put out messages that could be used - although the messages do not line up with the actual button presses. The bottom 2 buttons do not actually log on or off - just last heard from messages. My issue is very much like one posted from August 2016. The fix was to update the device_types.xml and device_features.xml files. But I could not find them in my Ubuntu installation - and I was not sure this was still the correct way to fix my issue. Anyone else have this issue ? Solution ?
