Manual dial for power (nordpool) like thermostat

I want to make manual dial like thermostat but for power.
Lets say when electricity price is below 2 cents I want to use and when more than 3 cents , then switch off device.
How make this manual dial where can i choose this 2 and 3 and change theese.

This is probably not something you will get as a standard feature in HA, because it is too random when a device can set up like this.
You will have to make it with automations, but if you have a sensor of the current price, then it should be pretty easy to do.

Closing as a configuration question rather than a feature request.
