Harmony Hub

That's very interesting. Does it build on the current activities that we have, or would I have to rebuild them from scratch?

What device database does your app draw from to control the devices?

(Sorry for all the questions. I want to be absolutely sure I know what I'm getting into before I start messing with my hub.)

[EDIT] Looking at the install directions, we have to have an an Arduino set up as well? Can I use a Raspberry pi? Is there a separate setup for that as well? I ran across this link: [Release] HubDuino v1.1.7 - Hubitat to Arduino / ESP8266 / ESP32 / ThingShield Integration (ST_Anything)
