Creating a UI slider for testing

I’m starting from zero w/ HASS so forgive the basic question. I’m playing around with my ecobee and want to test the effect of setting the value of a “service” in climate.ecobee.

How can I create a basic toggle on the web gui that will change the value?

is most likely what you’re looking for. Then it’s just a matter of using of using the slider value in your testing.

Perfect, thank you!
