Gen 3 questions

I just got a Gen 3 dual-probe model. I have two questions:

1. Wifi and Internet--I love cooking on my portable grill when I go camping. I'd love to use my Chef iQ Sense at a campsite, but there often is no wi-fi available. Occasionally, there's no cell service, either. I don't need to monitor the cooking from far away (I never leave unattended fires of any kind in the woods, including propane in a grill). Can I still monitor the temps from something like 6 feet away using my phone's Bluetooth alone?

2. Settings--I figured out how to lower the volume of the base unit. Can I turn down the volume of just the voice? Is there a way to set my phone to vibrate instead of an audible beep?

I love the two different color probes! They're easier to distinguish when a juicy cut of meat is smoking.
