I have discovered an issue relating to multiple bulbs using the same name.
I thought if they were named the same they would both respond to a voice command simultaneously. However they do not. Grouping them is a part solution, that works for voice command, but not when setting up a timed function. In that scenario you can only set a group to turn on or off, light level or colour cannot be set. I would like to know if anyone else has come across this ?
