Options for BR30 color bulbs? I have six bulbs in my kids playroom I'd like to add color bulbs to. I am currently running Caseta/Alexa/ST all over the home, so I need it to integrate into my system. I know HUE is the leader, but confused as to when a hub is needed and when not? Also, there are knockoffs out there, much cheaper, but do they play well w/ Alexa/ST and the Lutron Aurora dimmer (which appears to be the best knob for these setups). Thanks!
