RELEASE Generic Media Renderer (DLNA Speakers). Cheap Sonos Alternative (Update V2)

Indeed, I installed Media Renderer Events, but I can’t get past the final “Done” because it tells me I have some inputs that don’t have a selection. “Oops! Looks like you need to double check some inputs.”

But all inputs are selected or at least enough of them.

I have a play trigger: water sensor wet
I have a stop trigger: water sensor wet (this is odd, it should let me choose “water sensor dry”!
On the chance this was the problem, I also tried a mode change as the stop trigger.

I have an Action: tried both Sound and Message

I have a selected “Sonos” speaker (really my JBL Soundfly.)

I assigned a name. Still, “Oops! Looks like you need to double check some inputs.”
