I should state the temp options for the top broiler is low, med, high lol no idea what temp those are.If it has a max operating temp of 275F then the top broiler is almost pointless... it can't really broil hahaha.
Yeah the Bluetooth feature for the MES has always been reported to never work which is sad since it is a major selling point but has never worked.
One of the guys on the forum uses and likes the Auber PID that has Bluetooth. I believe there are some quirks with the Auber Bluetooth unit BUT it didn't seem to be enough to keep the guy from really enjoying it.
If you don't even care about the top broiler then I'm pretty confident you could just do the rewire like this post mentions as long as you only find and connect the normal smoker heating element wires and they don't include the other broiler element in the circuit. In this case it would operate like any MES on a PID we have discussed in the past.
