Hi Floyduww;
Since I posted I spent last night tinkering your program to test. Turns out I had all sorts of environment issues with Python (i’m hopeless with it). I have “more results” with Python3, is that the correct environment for it?
Is there a way to test if I have all the modules loaded?
I can confirm it is receiving the UDP Hex dump, but only when I launch the app. I haven’t seen any other packets coming in but that I suspect is the program crashing.
It appears I get all sorts of python errors, which i’m putting down to either modules not on my machine or the hex data been in the wrong order from the Meater+ hex packet and causing issues.
Hex dump below is;
Meater+ probe
Target Temp 57
Internal 18 (maybe 17)
Ambient: (too low, no reading)
“Sirloin Steak, beef”
(ignore all the extra prints, I was slowly trying to work out the data packet break down, let me know if you need me to remove).

Thanks for your efforts, this is great!! 
Let me know if you need more Hex dumps under different conditions etc!
ta!
Edit; the MQTT is working, I have receiving “off” when the “blockOff” sends/prints
