Display negative values in HA Dashboard for a Deep Freezer

Configuration Frontend
1

All,

I am looking for a way to display a negative value to my dashboard from a sensor that is in a deep freezer. I cam using an ESP32dev board running ESPHome with a Dallas temp sensor. I have a reading from the ESP32 and the sensor of -15 deg F. I can see the value in the ESPHome webserver on the ESP32 so I know the sensor is reading correctly. I am looking for a way to display it in the dashboard. The default Gauge card shows 3 deg F no matter how low the temp gets. Is there a way to display the actual temp in the dashboard on a card? Any help is appreciated.

Thank you

Please show us what the states tab in dev tools shows as the value.

Here is the reading that ESPHome is showing in the webpage of the ESP32

Odd. What does the esphome log say when the sensor reports?

Pull up the bus: esphome is reporting in Celsius and HA is reporting in Fahrenheit. They are equal.

(3°F − 32) × 5/9 = -16.11°C

wow that is an oversite on my part. I just changed the ESP code to send F and what do you know it is all the same. Thank you for the help.
