Diagnostic Port on 2014 Tacoma

I recently installed a device called Drivewise in the diagnostic port of my Tacoma. I have read that this device should not be plugged into this port for an extended period of time and could even invalidate the warranty. Does anyone have any info on this?
 
My scangauge has been plugged in for about 3 years now. No issues and the dealer simply unplugs it if they need to access the ECU.
