I am getting the same issue. We use HomeWave and it constantly shows the dreaded red dot to indicate the device can’t communicate. It comes and goes, although today it’s hasnt cycled and all our bulbs show unable to communicate, so maybe the Hue bridge updated again.
My assumption it’s the issue of the Hue plugin and the Hue bridge being incompatible versions, as the plugin does indicate the version it supports, which appears quite old compared to the latest bridge.
I really hope Vera fix this as I don’t have the energy to totally redo all lights and logic in reactor again.
mind you it still works, and reboot fixes things, so maybe is a vera memory issue.
