Jasco Dimmers as Switch - HA Still Dimming

Configuration Z-Wave
1

I’m using some UltraPro 39351 / ZW3010 Dimmers in switch mode and they work great for local control. 5 taps up, 5 taps down, and they act just like switches. Parameter 16, switch mode, is also enabled.

Home Assistant on the other hand slowly dims these on and off when you turn them on or off from the device config and/or lovelace. The only way to defeat this that I’ve found is by passing transition: 0 when calling the light.turn_on service.

Is there a more reasonable way to do this other than making templated virtual lights? Should I create a virtual light for every one and use that in my dashboards?

These particular switches do not have parameter 7 or 8 to change the dimmer steps for Z-Wave. They just have parameter 6 “dim rate”, which is set to the default (Dim Quickly).

You can use light profiles to default the turn-on transition duration to 0.

You may be able to add those parameters if supported. Need to modify .json file for the device.

Again, if it is supported

Thanks this was exactly what I needed and works great. Too bad it’s hidden in a config file that requires a full restart.
