I just got my Model #1 a few weeks ago. I have it in a covered area so I don't have to worry about rain or anything. However, I didn't want dust or bugs getting into it. I noticed that the hole for the probe / smoke was about the size of a wine cork. I ordered these wine stoppers https://www.amazon.com/OXO-SteeL-Expanding-Wine-Stoppers/dp/B074ZPLPS3/ref=sr_1_1?dchild=1&keywords=OXO+SteeL+Expanding+Leakproof+Wine+Stopper&qid=1609542976&sr=8-1. They look like a factory accessory when installed. You push down on the stainless steel top and it expands the stopper to seal the space and it sits flush on the surface. I think it looks and works great!
