I too bought an iGrill2 during the time it was under iDevices and could never complete a smoke without losing connection. Then I bought a Maverick and it works flawlessly. But after Weber took over the iGrill I decided to contact them regarding my issue and they sent a new one to me and--while I don't use it for all my smokes--it has not lost connection, yet, during the handful of times I've used it. I never heard of Tappecue until reading your post.
