John Mclemore Signature Series - Exclusively at Lowe's
Got the exact same myself.
I got it because it didn't have a built in thermometer. I wanted to get my own.
Well, actually, I had my own, now I have a couple of more good ones.
I got a
ThermoPro TP-08 WiFi with a 300' range.
More recently I got an
Inkbird XS because it is Bluetooth and has 4 probes. But came with 3 probes and a grill sensor.
I later bought a 4th meat probe, so I'd have probes for multiple pieces, like when I smoked 4 slabs of Bacon at once.
Both are sponsors here on SMF, and Both offer us a discount code on their products.
I simply drape the sensor leads out the door gasket. No holes. And
my MES 30 is modified and has a stack (chimney) on it. So the vent is not an option for me.
In reality, the TP-08 has a good range at my home, and is a good all-around BBQ thermometer.
The Bluetooth has less range, but more pzazz. Has graphs, more alarms, and is fun to look at.
