LIke Jim, I use an Inkbird. Mine has spots to run up to 6 probes. The one I got is Bluetooth only, but it's strong enough that I can be inside the house and 20-25 yards away and still get signal. Works great for me.Inkbirdbbq is a sponsor here. I have their 4 probe wifi that I love. Usually post up discounts on here and they are available on Amazon.
