Thanks…Like you I want to keep my app count down and ‘keep it simple’…That is why I created my own apps. However, as ST has evolved I have actually scuttled many of them in lieu of built in apps…a good example is the Smart Lighting App…It literally replaced 2 or 3 of my independent apps…Again, I have had my apps published by ST, but this is for fun and not for profit, so it comes down to what ever works.
The Alexa app is the same way…if you want something that just triggers a routine or changes temperature on a thermostat, this is your app. If you don’t use routines and want various unique things to happen when you trigger a virtual switch, than Rule or Trigger Happy may be the solution.
Gotta love some of the aspects of the open ST model…there is never a right answer…there are multiple right answers depending on your situation.
