Problem description:
I have regularly added Olisto on Ewelink and Google Home successfully but I cannot use them in the formula because the icon remains gray. If I click on it, the message “this channel has no action” appears. Where am I wrong?

Hello, what channel are you trying to click? Ewelink or Google Home?

they both give the same problem
