Hi ScoobaSteve2884,
Although I'm new to posting on this forum, I've been a lurker for some years.
This reply is about thermometers, because Hab mentioned getting one, and because some of the thermometer posts are rather old.
My old thermometer died on New Years Day, so I went searching for new one.
My two primary criteria: wireless, so I could see the temperature(s) from the comfort of the house;
and multiple probes.
There are three basic kinds of wireless: Bluetooth, Wi-Fi ("wifi"), and "other". I've had far too many problems with Bluetooth over the years, so I would never get one with that ... and the range is far too short. The very few Wi-Fi thermometers tend to be expensive ($100 or more), and generally require that you use a phone as the receiver, and you may encounter difficulties with setting them up to connect to your house router/mesh. The "other" (like the Enzoo, below, uses) generally is very easy to use, and has excellent range.
Some Bluetooth and "other" transmitter/receiver pairs (ok, almost all the ones I've seen) require you to "synchronize" the transmitter and receiver. Usually, that's as easy as powering on the xmtr first, and rcvr second (within 30 seconds or so). (The Wi-Fi ones "pair" differently, of course, by having to access your home network, and then be findable by your phone.)
I bought two "other" wireless thermometers this month: a single probe Maverick, and a four-probe Enzoo. (I needed something fast, and only the Maverick was available locally ... I then ordered the Enzoo from Amazon.com)
I found the Maverick dropped signal several times during a 5 hour period. Not recommended.
The Enzoo,
https://www.amazon.com/gp/product/B07Y385YR3has 4 probes, and has worked flawlessly. The range is easily from the smoker to the far back of my house.
The xmtr/rcvr come "pre-synchronized" at the factory (but with easy instructions on how to do it yourself, should that be needed).
I use one probe for the smoker temperature, and up to three more for meat temperatures.
The Enzoo transmitter has a magnet, which lets me simply stick it against the side of the Bradley, which is quite convenient for me.
It comes in a carrying case

The Enzoo, Maverick, and a number of others, have the ability for you to set high/low temperature alarms (e.g., if you want to be alerted if the smoker temperature drops below 150, or (for cold smoking) if it rises above 75 F).
The "low temp" warning was very useful last year, when my heating element burned out while smoking a pork butt! (Alerted, I pulled the butt and finished it in an oven.)
There appear to be a fair number of Enzoo clones, all Chinese made, on Amazon ... I have no knowledge as to how they compare with the Enzoo (indeed, perhaps the Enzoo should be included as a "clone" of something?)
Note: a couple of shady vendors advertise "Bluetooth Wifi" wireless ... there is no such thing (in each case, it's a Bluetooth wireless device).
Hope that's of interest/use!
