@david-jones Have posted the app now as part of a GiHub repository I'm building for TRIGGERcmd on PC and RPi: djaus2/TRIGGERcmdRPi Look for WhatCanISay app.

@david-jones, awesome. I'm so sorry for the trouble. Please email me a copy of that commands.json file so I can prevent that problem in the future.

@david-jones, if you enable the TRIGGERcmd Google Action it should work. You've only enabled the TRIGGERcmd Smart Home Google Action so far. I like the Smart Home action better personally because it creates on/off smart home switches for each of your commands, so Google Assistant just has to match your words to one of them when you say turn on X or turn off X. It has a much better chance of matching your words to your commands because it has a list of them ahead of time.

@david-jones, have you considered this tool? https://github.com/vishen/go-chromecast It's a Go utility so they have binaries for all different OS's, including arm7 (Rpi).

@david-jones, thanks. I'll update that article.
