[RELEASE] Follow Me - Speaker control with priority messaging, volume controls, voices and sound files!

I have limited physical sensors and switches in the home (so far... I'm wavering on having a home full of motion and contact sensors that all need battery, or wires off some sort of USB source). I am trying to see if FM can target my Google speaker in the office when I'm in there.

I have an app-driven presence setup that can tell that my laptop is on (a basic 'hello world' page serves off the laptop, and the app runs every 5 minutes and if the page serves without a page not found error, then presence is true).

Driver:

[UPDATED] HTTP Presence Sensor

Any other time (when not present), I want FM to speak on my phone (using Join by the developer of Tasker).

Driver:

[Release] Join Api Notification Driver

Both speakers work correctly independently, but is there some setup I should use to have Join be the default, and use the speaker if I'm in the office?
