Long story short, I had to replace my router, and it was set up with a default 10.0.0.x scheme, and I switched back to my standard 192.168.x.x scheme, but the ST Hub had the Hue’s 10.0.0.x address locked in, and therefore i couldn’t control anything Hue. Took me a while to figure out how to force a change, so to save others the trouble:
- Open Hue (connect) under Automation/SmartApps in the mobile app.
- Choose your bridge
- You’ll see “discovery started”.
- Wait, and after a few minutes, the new IP will be discovered.
