You are absolutely right about needing a longer hose. I set a 4-foot step ladder next to my WSM and hang the controller on a clamp attached to the 3rd step. The only problem I have had with mine is that it occasionally gets stuck in the "open lid" mode and won't settle down and work correctly until I reset it two or thee times. When it works, the IQUE 110 makes cooking on a WSM pretty much foolproof.
