Yeah, more probes would be nice. You'd have to just buy more whole units, but I'm not sure if more than one would work with the app. Even though the bluetooth range says 115 feet, I'm skeptical it would keep a connection in my house. Must be my walls or something. I'd prefer if it were Wifi, and cloud, so I could monitor it from the other side of the earth. The app looks like it is Apple products only right now, which is fine with me because that's what I have, but I'm sure a lot of people have Androids or other. Looks like a great replacement for a Maverick though. Does everything a Maverick does, plus has an app. And for less money. Don't know why Maverick hasn't jumped on any new technology. They are going to lose their market share in a hurry with all of the new products coming out.
