Thank you Harry. I was looking at the app while sitting at my desk, and see now that it automatically updates.

In looking at the different timer screens in the documentation I see that coolant temperature is one of the items displaying on the Timer. I have the Petrolhead Edition v20.0.11, but my Timer doesn't look like those in the documentation. I have Lateral G, Lineal G, Straight MPH and Curve MPH instead...

Wish I'd have stumbled upon this thread before buying mine. Just used it for the first time this weekend, and although at the start of my first session it was green, I got no data into HLT.
