Excellent digital thermometer for smoking/bbqing
I purchased the TP28 to replace an inexpensive bluetooth thermometer received (and returned) as a Christmas gift. The bluetooth thermometer continually would have issues connecting to the app, even when I was standing right next to it - essentially unusable. On top of that, the button cell battery died after only a few hours of use.Enter the TP-28. This thing is everything the other thermometer was not. 1: Simple (no buggy app to install or deal with) - and 2: reliable (never once had an issue with the receive not picking up the signal from the transmitter). I didn't test whether the 500ft claim is truly accurate, but I did take the transmitter all over the house without any trouble picking up the transmitter.As for accuracy, I checked both probes multiple times (before and after my cook) and the one probe was spot on (212 degrees in boiling water) and the other initially read 211 (but later read 212 on my 2nd test).A few minor improvements I'd love to see added in a future version:1) I wanted to see what would happen if the transmitter dies, so I tried turning it off as well as removing the batteries to simulate the batteries in the transmitter dying. Unfortunately, nothing happened on the receiver except an indicator that flashes when data is received stopped flashing. Digging through the manual, it looks like there's an alarm after 30 minutes. For me, this delay is way too long. I'd rather have it be as short as 1 minute to ensure the grill doesn't change outside the set temp range and I don't get notified. It would be nice if this delay was user-configurable. I'd like to be able to use this thermometer overnight for long smoke sessions, and not knowing for 30 minutes if the transmitter battery dies is a bit concerning due to the possibility of the grill temp going outside the target range.2) no way to disable beep when buttons pressed. When you're messing w/ programming the transmitter before starting a cook, all the beeping can get annoying every time you press a button. I wish there was a way to disable the beeping, as you can see the display change when you press a button (so no need for an audio cue as well)3) I think the transmitter's alarm only has two settings: flashing the backlight and beeping. I wish there was another option: off. When smoking overnight, it's nice to have the outdoor alarm be silent, so it's not making noise that could disrupt people sleeping in earshot of transmitter. It would also be nice to not have the flashing backlight unnecessarily wear down the battery.These issues are fairly minor, and overall this is an outstanding product. I don't know how I've gone so long without such a device, but thanks to the TP-28, never again!
