I don't know when this changed, and I believe that I have used these successfully in the past. I have a number of devices that I use the Level template to adjust their values like humidity set points and sleep number bed levels. I was doing this before you could directly set a variable in the dashboard and currently utilize a rule to set the variable.
In the end, that background shouldn't have impact on the following: If I set the level with the Level template in my dashboard, a single click of the up or down button increases the value by either 5 or 10. I anticipate that this was +/-1 in the past.
If I change this to a Vertical Level or even a Dimmer Template, it works as expected. Anyone else using this and seeing similar issues?
