Confusion about zwave fans

It seems that in the early days of HASS, the GE fan controller was classified as a light and it could be voice controlled by telling Google Assistant to dim or brighten the fan. That is my ideal scenario.

However, it appears that the fan component has since been updated to not allow brightness anymore… now it does speeds… however, I can’t get voice controls to work for anything other than “on” or “off”. How would I set the speeds of a fan in HASS using voice controls?

Do I need to set up custom scripts for this?

I don’t use Google Assistant but I use Alexa and I control my fans by just saying “turn on the fan to low”, etc.

Have you tried adding the speed setting to the on command?

I have not yet tried it in one statement… I will try that and report back.

This didn’t work… I wonder why it would work with Alexa…
