I checked, you can see the temperature on the graph. But as you said, if you have a histogram from a long trip, you don't know very well what the current temperature is. If you drive in the mountains, an indication of the temperature as a number would be great. Example: 1. You are going uphill and the display shows you 73 degrees Celsius 2. You know that you need to reduce the speed or you will immediately activate the limit A on the graph the measurement accuracy can be read + -5 degrees Celsius and often will cut off your power. If you will be doing version 0.5.0, please think Do not display the temperature in the form of a number. You are doing a great job I have paid you a paypall amount and I encourage the rest of the people to do the same.
P.S. On your YouTube channel under the battery you had the current value in volts, e.g. "51.2W" how to turn it on?
