I have a PE953 Intermatic Z-Wave Pool Controller and it perfectly integrates into HE.
To control the variable speed pump there are 5 switches (each can go on and off) represented by the speed, 0 being the slowest and 4 being the fastest.
Question: Is there a way to create a device that will turn these 5 switches into a single slider?
Sounds like you could create a virtual dimmer device, and then with a rule machine rule (or a few rules), configure the virtual dimmer to turn on/off each of the five switches when set to a specified dimming range?
I told you on the HA Community Page that I would help you with that here .
However, @marktheknife got you off to a great start.
In your example, if the slide is 0-20, then toggle switch A; if slide is 21-40, toggle Switch B,.....if the slide is 81-100, toggle Switch E. You might consider adding a 6th section that doesn't do anything just to have a place to move the slider without affecting any of the switches.
I did this previous with three options but have moved since and deleted the dashboard and rule because it was unneeded.
