Yeah, the parameter isn’t shown in the UI, probably due to that bug that poptart911 mentioned; however, you can still set the parameter directly: Settings → Devices & services → the “… Devices” under Zigbee Home Automation → click on the fan switch → Device info card, the ⋮ to the right of Reconfigure → Manage Zigbee Device. Change the Cluster to Inovelli_VZM35SN_Cluster, select the attribute you want to change, such as led_intensity_when_on or led_intensity_when_off, enter a Value, then click Write Attribute.

Worked great! Thanks!

Still need a way to get the switch to be read as a fan, and not a light though. Being read as a light causes issues with Google Home integration.

ZHA has a cool option that will let you change the device type (note even with the type being fan, it shows up as a switch at first but you can change that too, see below starting from the device page).
Then you can just exclude the old entity from Google Home if it’s also showing up.

I dont see a “show as” option…
The switch is on the “light” domain, not the “switch” domain like yours.
Wow this is awesome. I had no idea. I don’t see the option in the UI either, so I tried using the YAML instructions in the ZHA documentation you linked to. Unfortunately it doesn’t seem to convert it to a fan.
Here’s what I tried:
zha:
device_config:
84:71:27:ff:fe:93:17:24-1: # format: {ieee}-{endpoint_id}
type: "fan" # corrected device type
In the meantime, I created a second entity that takes the fan switch “light” and creates a new dedicated fan entity. I wish I didn’t have to have a second entity, but it works well in the interim. Here’s what I did in case anyone else wants to do it too:
fan:
- platform: template
fans:
living_room_fan:
friendly_name: "Bedroom Fan"
value_template: "{{ states('light.bedroom_fan_switch') }}"
percentage_template: >
{{ (state_attr('light.bedroom_fan_switch', 'brightness') / 255 * 100) | int }}
turn_on:
service: homeassistant.turn_on
entity_id: light.bedroom_fan_switch
turn_off:
service: homeassistant.turn_off
entity_id: light.bedroom_fan_switch
set_percentage:
service: light.turn_on
entity_id: light.bedroom_fan_switch
data_template:
brightness: >
{{ ( percentage / 100 * 255) | int }}
speed_count: 3

Does anyone know (or even better, has anyone tested) whether these will work for florescent lights when run in the on/off configuration? Mine came in yesterday and I have spots picked out for 4/5 but still trying to figure out what to do with that 5th one.
They are not compatible with ballasts. In theory you could rip out the ballasts and install ballast bypass bulbs (LEDs).
Edit: @jetpacktuxedo Did you mean to comment on the Light Switch or the Fan Switch?
I meant the fan switch, as I was already 99% sure that the light switch wouldn’t work for the same reason that DC motors don’t work with those (high startup current I think?).
I figured the tweaks that allow the fan switch to work with DC motors (like bathroom vent fans) might also allow for turning florescent ballasts on/off but was hoping for confirmation before I tried it.
I get what you saying since it handles the load differently. Based on this graphic I think it’s a no go with the fan switch.
I understand your logic and this might be one of those cases that is officially NOT supported but might actually work. HOWEVER…
I would seriously consider converting your old ballast fluorescents to the non-ballast LED tubes as suggested by @stu1811. It’s an easy process and allows you to keep the existing fixture/hood/shroud. And it would be officially supported with a smart light (not fan) switch.
I did this several years ago and never looked back. Like it so much better.

I have installed one fan switch so far and noticed that the LED’s on the Fan switches are much brighter than that of the 2-in-1 blues. Has anyone else noticed this?
And it uses less power saving you money to buy more toys

Yes. There might be settings to control this, haven’t had time to look into it.
hopefully this isn’t too far off topic - but, i’ve been considering this conversion for my workshop - which has 14 or so fixtures. do you have any recommendations on products for the conversion, etc…
Yes, they’re also completely different LED’s. For example, Blue will look like a darker blue if next to a blue series light switch which will look more like cyan. This is likely because they were built by two different companies or they’re using a different source for the LED’s in these. What’s good about that though is that you’ll always know which is fan and which is light. They will likely never match no matter how much you fiddle with the settings and brightness of the LED. Trust me - I’ve tried.
Anyway I’m still very happy with them. Mine show up as fan’s properly using the external converter for Z2M. The only issue I see is that not all the parameters available to the switch are in that external converter and the LED control specifically for notifications isn’t going to work with the way it’s written. Brightness of the LED should work though.

Unfortunately you can only do that when the device shows up as a switch in HA. So if you change the device type in the configuration.yaml file like that link showed, it should change that from a light to a switch and then you can tell it to present like a fan.
@MasterDevwi - did you try that exactly as-is, or did you update the ieee with the ieee of your device? You should be able to go to the device page, expand Zigbee Info and grab it from there. Type “fan” didn’t work for me, even with that it changed it to a switch, but I was able to change it from a switch to a fan via the device page.

Thanks, I swapped out the IEEE in my config but didn’t for the one I posted here. But I just realized I didn’t include the endpoint number. 
Once I specified endpoint 1 it correctly showed the switch, and I was able to convert it into a fan.
Weirdly, however, the fan only supports on/off, not high/medium/low/off. So I might go back to the old implementation until the device correctly appears on its own.

Just fyi, The Blue Series Light Switch and the Blue Series Fan Switch are both built by the same manufacturer
