Most Zooz light switches are not rated for use with fans, home appliances, and motor loads in general - but there are a few exceptions.
To have on/off control of your fan, you could use the ZEN21 Switch or ZEN23 Switch as long as the fan is rated under 3A or installed in the last 5 years. If you currently have a remote control receiver controlling the fan, you'll need to remove it.
If your fan is rated over 3A or is an older installation which typically draws more than it's rated for, we recommend using the relay part of the ZEN30 Double Switch. While the ZEN30 dimmer and relay parts cannot control the speed of your fan (if it has that feature), you'll still be able to control the speed from the pull chain or existing remote control. You can learn more about the types of installations the ZEN30 switch can be used in from this guide.
The ZEN21, ZEN23, and ZEN30 switches are the only ones rated to handle the specified fan loads. Our other Zooz switches, especially our dimmers, cannot be used with any type of fan. The high inrush current, or amount of power a motor draws at start-up, will damage the switches immediately or over time. Aside from the 3 models rated for use with fans, Zooz switches should really only be used with lighting within the recommended loads.
To learn more about the required load minimums for Zooz switches, please check out this helpful article. The maximum loads for each individual Zooz switch can be found under Specifications on their product pages. You can also check which LED bulbs work best with Zooz switches on this compatibility guide.
