Switch for a bathroom fan?

So I wonder if anyone has tried this with a ceiling fan and light kit… I can’t imagine they’d be much above 1-2 amps or am I way underestimating?

I currently have my fan hooked up to a HB Zigbee controller connected to power with a normal dumb switch… It would be nice to use a Red Series, disable the relay and use the buttons to control the Zigbee controller for the light and fan speed… At least until the Inovelli fan switch is released…
