Input Sliders (to fake a climate control)

[Linwood-F]

Long story short - my home "climate" is an overly-complicated node red system with four thermostats controlled by node red (i.e. whose set points are continually modified). All this is driven by low and high temp set points per zone, which are Home Assistant input_number entities.

Is there any way to have an input_number entity changed by the nspanel by a slide, as it is in HA? I've tried putting them in various places and as entities I can see their value, but not change them. I was hopeful I could use a button and it would open a page but it won't take it as a button.
