I've noticed an issue that I can't seem to resolve. I've used the Alexa-Hue Bridge plugin for quite a while now and it worked perfectly up until a few months ago. I'm having issues all the time where all of my Insteon devices will work properly right after discovery. Then, some time later (maybe an hour, maybe a day) individual devices stop responding using Alexa. I just get a long pause then "the device is not responding" response from Alexa. However, my device groups and scenes seem to work fine all of the time. For instance, if I use the command "turn on all kitchen lights" it will activate my device group, but if I use the command "turn on kitchen sink light" (which is included in the same device group), I'll get the not responding error. If I run discovery again, it will work for a short period of time again.
I'm using 2.0.11 version of the plugin, Indigo 7, and I've even tried switching to a static address (since my Indigo server has a static IP). It's pretty frustrating since that is the function I use on my Echo Dots 95% of the time, and that it worked flawlessly for months before. I've helped two other people with nearly identical setups and never had an issue.
