It's not WiFi or Bluetooth. No app on the phone, but it's perfect for me. The unit comes with a transmitter that stays at the pit which can accommodate 4 probes, has a bright orange back light and can switch between C and F. The receiver also has a back light and a host of functions I'll go thru in a bit. Three meat probes and an air temp probe, along with two grill clamps to hold them at grill level.
I bought a short rib rack to do up tomorrow so I'll walk you thru the setup and features as we go and you can follow along with me as I smoke my first big chunk of beef.
Some notes first though. The unit doesn't feel like it's sturdy, it's not something you would want to drop I'd imagine. The range as I tested a cooling grill last night covered my whole property inside and out (they advertise 1500 ft like of site) which is perfect for me. It doesn't come with instructions but they do have them on their website which are easy to follow. The units are rechargeable internal batteries, so no messing with coin or AAs just charge with a USBC cable (they provide two) into a regular usb charger block (they do not provide).
We can do some range testing tomorrow and see how it holds up to use. I'm pretty excited
