If so, Im wondering is the source code for this device open source? I havent been able to find anywhere how I can edit the way it runs or stats it shows ... your repo, seems evidence that there is a way to modify how it runs?
I ask cuz, Im looking to change simple things that read out on the display by modifying the code on the device (like converting C to F units, and change various other things the display outputs) ... and Im trying to see if thats possible, before buying.
Thanks much!
