Change degrees C to Volts for tool tip
Funny mistake I just noticed:
If you hover over the Voltage Sensor display on the top right, the display says 12.1 V actual, Minimum: 12 °C and Maximum: 12.3 °C But Voltage isn't temperature
@chrishamm please see this bug report!
Thanks! I'll fix it.
Edit: Fixed in v1.22-b1.
