So I just got my RT 590 deck boss set up. Finished the burn in, then afterward decided to connect to wifi. I have a Google Mesh system, and was reading about the 5 mhz vs. 2.4 mhz issues and got really confused. So, I just tried connecting like any other device. I all seems good. I can control the grill through the app just fine. But then I noticed a "Smart Diffuser" listed in the app. What the heck is that???
