I'm new to Node-RED so please go easy on me here 🙂

I have created a flow when I change a sensor from off to on it will dim down a light bulb I have in Home Assistant.  
Unfortunately when the dim comes to 0 it turnes off the light. so I would like to make the flow only be allow to dim down to 1 instead of 0, is there any way I can do that.

Here's how my flow looks like now:

```auto

Your three flows have 10 nodes of which 8 are Home Assistant specific (I think). Probably you will get more help in the HA forum.

But there is a Range node which might be useful:
