I have HSM set up to turn a Group of lights Red upon a leak sensor detecting water. I also have the same light Group set to flash, but they don't flash. The Group type is "Group Bulb Dimmer-2.1" and the lights are Zigbee RGB bulbs.
Is there a way to get them to Flash? Do the devices need to have the new "Flash" Capability to flash (I assume not, otherwise it wouldn't make sense for them to appear in the selection list), or is it that you can't flash RGB zigbee bulbs?
