I have multiple installs of the smartapp. That means a complete install to include the lambda and Amazon developer setups for each install.
The macros are setup like this.
CoRE has a ton of DO piston, one for each macro.
And each piston looks like this....
It's a lot of work to setup, but speaking to Alex's feels more natural.
"Alexa, tell Home to tell Alex to come downstairs"
I just say:
"Alexa, tell Alex to come downstairs"
My speaker are Wi-Fi/ Bluetooth made by a company called Pure.
The speakers are model Jongo s3 and t1.
I use this smartappfor st integration.
