I thought this was your plug-in, but I no longer see it listed in the Forums. I've been using it since v1 without a problem, but I just upgraded my Mac to Catalina and I had recently upgraded Indigo to the full 64-bit version, just prior to the upgrade from Mojave to Catalina.
Once the Catalina OS upgrade was done, Indigo seems to be fine, but since all my commands to Echo devices result in "xdevice is not responding", I can only assume that something has happened to the connection between the Indigo Server 7.4 and the Alexa-Hue Bridge v3. This plugin may longer be supported, and if so, my apologies, but I'm not sure what, if anything has replaced it. I'm pretty dependent on Echo devices for home control via Indigo.
I've tried restarting Indigo Server, and the Alexa-Hue Bridge seems to be up and running in the Devices list. Anyone have a good direction for me?
Thanks!
