Visual indicator for current temperature in thermostat card

I think it would be great if the thermostat card which currently looks like this

climate1

could also have an analog “needle” to show the current temperature, along with the numeric value. Like:

Our church has seven thermostats, and it would be a lot easier to “watch the gauges” to see if any of them are out of the normal range, rather than having to read each of the numbers.
