Sonos (TTS) - Send a 'Say' Command ?

Hi

I was wondering if it was (or could be) possible to send a ‘say’ (TTS text to speech) command to a Sonos device?

I can see the lul action option, but could not work out how to
get it to work.

Should be possible, once you work out the right URL to invoke the TTS action. Then set up an action button, switch it to Vera action, and paste in the part of the URL following the action= part.
