New Fan switches, Need help with piston


1) Give a description of the problem
I just installed some new fan speed switches. Leviton ZW4SF-1BW Decora Smart z-wave 4 Speed Fan Controller.
Need help switching fan speeds based on room temp. This is a piston I was previously using with virtual switches. I went through and replaced the virtual switches with the actual fans. The piston seems to be changing correctly but it is not actually changing the fan speeds. In ST the apples indicator shows “off, low, medium, high, max”

2) What is the expected behaviour?
Fan speeds change based on temp.

3) What is happening/not happening?
Piston is working correctly but fans speeds are not changing.

**4) Post a Green Snapshot of the piston!


The setFanSpeed() command takes a positive integer argument so try 0, 1, 2, 3, 4 as the values, rather than the strings.
