Chris Young seems to have confirmed that they are working on a longer probe: https://www.reddit.com/r/combustion_inc/comments/1pvmkxb/stumps_smoker/?utm_source=share&utm_medium=web3x&utm_name=web3xcss&utm_term=1&utm_content=share_button

The CPT didn't quite fit through the hole. The corners of two tiles on the outside are the restriction. I may get a diamond burr to shave them a touch.

@sobiloff@braindoc Have you tried actually using it? As @Syzygies suggests, the short insertion may work well, albeit differently than a longer insertion.

I was just re-reading this post and got to thinking about ways to measure this. I was trying to conceive of a way to have sensors in both places simultaneously, like the CPT does, when it occurred to me that a CPT inserted from the inside of the KK dome might be able to do just that. I'll see how it fits tomorrow when my KK has cooled down from today's cook.

I don't think the folks on this forum are the ones to ask for FAQ suggestions. My suggestion would be to ask for questions within the videos. That said, it should be recognized that the KK isn't a product for everyone, as not everyone appreciates working with an excellent tool enough to see the value relative to the price.

I enjoy overthinking! (Plus I can't help doing it.)

Although you didn't ask me, and I love their products, this is pretty much par for the course with Combustion. But then, we have become an impatient society.

I have a FireBoard 2 Pro, which works well with my 21". I got the pro because it uses thermocouples, which I prefer for the broader temperature range and I believe to be more durable. I'm using it with a BBQ Guru Pit Viper fan, because it fits into that handy port. I replaced the Tel-True thermometer on my KK with a thermocouple probe. Even if I am not controlling with the FireBoard, being able to easily save a log of what was going on during a cook has been a wonderful learning tool. I also have several Combustion V1 thermometers. As a geek type, I find them to be a lot of fun. The prediction feature is iffy for low & slow, but works well when grilling. I haven't had any connection problems. They do present a lot of information in their app, maybe too much for someone who only wants to be told when things are done. Again, being able to save a log is great. Their customer support has been very good. Combustion is supposed to be releasing a totally wireless controller soon. They have had some teething problems with their products, so I don't know if I would want to be the first one on the block to get one. It is not clear yet if the sensor part will be long enough to work with the thickness of a KK.

It looks to me like there was some sugar in that mop. If so, sugar burns at 300°F. I would lower the temp and let the thermometer tell me when it was done. Or mop at the last minute only.

I replaced my Tel-Tru with a thermocouple probe that can extend up to 5.5 inches past the inside of the dome. I have noticed temperature anomalies if I have it too far in when there is something on the upper grate. I too have noticed that the dome and grate temps converge over time, but that can be quite a long time. My main concern with having the dome probe close to the dome's inner surface is that I would expect it to respond rather slowly to changes in the interior air temperature, which would be an issue if you were using it as input for something like a fan controller.

Based on what they have published so far, I estimated only 6mm or so of the probe would extend into a KK. I don't think they ever did the tweak Chris mentioned.

You will likely have to do some experimenting to get things dialed in, which should be a pleasurable task in itself. I started out with a round cordierite stone (not the KK stone), aiming for 700°F, which was what worked on my previous rig. 700° was too hot, so I went to 600°F. The tops were burning before the bottom crust was done, so I switched to a 1/4" steel. The bottoms burned before the tops were done. Then I tried with the stone on top of the steel-success! 600° for about 5 minutes. I don't even have to turn them. I have a 21"KK, so YMMV. There are lots of more experienced experts here who will have more tips, and there is for sure more than one path to pizza nirvana.

What is not clear to me is how far the sensor would reach into the KK. Chris was surprised by the thickness I measured on mine. I wouldn't think having it just barely peeking through the hole would be ideal.

It is not clear to me if the GGG temperature sensor probe is long enough to work with a KK. Chris indicated that they would be posting dimensional drawings a while ago, but it hasn't happened.

I keep my FireBoaord turned on even when I'm controlling manually. I like to have a log of what I did and what happened as a result, so I can learn a little bit along the way, without having to actually pay much attention in the moment.
