WTH is so difficult to make a light blink for a couple of seconds?

[DvdNwk]

Alright, so it isn’t there on my list of effects:

I was asking because I’ve tried to use flash on the lightbulb, but it didn’t work → and yet I haven’t seen any error or nothing, so I wasn’t sure if it’s me, or the HA, or the lightbulb

Light.toggle: flash -> inform when not supported

I’ve just tried to create a blinking/flashing animation for my lightbulb with the flash: short option, but it didn’t work. It turns out, it works only for lightbulbs that support it. Feature Request: indicate to the user when flash doesn’t work: write an error to the logs when flash is an invalid (unusable, not working) option of the service call.
