Newly upgraded to 4.3.8 from 3.4.5 with Insteon Beta binding. After upgrading, installed the 4.3.8 Insteon binding, and most devices began working after taking a while to read device databases, etc.
A few devices stuck in Config pending state, which seemed to be resolved after disabling/enabling the device, and then using the buttons on the device to turn it on then off (I have not tested to see if all these steps are needed).
I have one device I tried to remove, and it stuck in “Removing” state. After an OH restart, it went back to Disabled. Another try at Removing left it stuck in Removing state again; without another restart, clicking Remove again raises a prompt warning that force removing may cause instability, do you really want to proceed. I cancelled…
A note (and I’ll raise a request on Github for this) – most of the Insteon debug messages show the device address as aa.bb.cc, but a few show aabbcc, making it difficult to filter for all messages related to a device.
I’m planning on moving on ahead to 5.1 soonish, so no need from my perspective to fix anything on 4.3.
