Hi, New user questions

Background, I started with Philips Hue gear for outdoor security lighting. I have the Hub, 3 outdoor motion sensors, 2 plugs and 6 bulbs.
System works just fine, convenient and reliable.
So I decide I’d like to dive into similar controls for other areas, and cover it all in one app if possible.
I have the V3 ST hub, bunch of switches, sensors and relays from a few brands.
I start setting up with my Hue stuff and the sensors don’t populate… I thought this would be easy.
I’ve published code by 2 users for the sensors to my device handlers but I’m not even sure if the new app supports it? Should I be trying the classic app?
