Works Great!

I replaced a dead zigbee controller with this one, and it’s fantastic. I was expecting some lag when controlling it, but there is none. It arrived pretty quickly and was easy to install.

Works well

I installed it on a 120v ceiling fan and it works perfectly. All three speeds run as expected and the remote works also.

Needs dimming

Product works great and would install it on every fan except it doesn't have dimming. With that said I will only be installing one. Also you need a PhD in hieroglyphics to decifer the remote that comes with it. Add dimming and clean up the remote and will give five stars all day

Thank you for your feedback.We will submit your requirements to our technical departments, if plans, we will update, thanks.
