Switching DC Bath fan with Blue 2 in 1 or Fan?

I pre-ordered one of the new Blue Series fan switches for use in a bathroom exhaust fan. Since placing the order I’ve been thinking about my fan that was recently installed. This is a DC fan with soft start functionality. My knowledge of electronics focuses mainly on low voltage devices so I’m not entirely sure the characteristics of a DC motor driver.

Would a DC bath fan like the one above be okay to be controlled by a normal blue series 2 in 1? Or is it likely that the power circuitry still presents as an inductive load even though the fan itself is not powered directly from mains voltage?

I don’t think either switch support DC fans.

Definitely not as a speed controller since it is a DC fan. But probably the fan switch in the Exhaust Fan On/Off mode if you don’t care about the two speeds. In that mode, I believe that the switch is working as a simple on/off, so I would not think the motor type would an issue. Inovelli should confirm, however.

Exactly this. Technically the fan can be set between two speeds but requires taking the cover off and flipping a switch. In my current use with a dumb switch it is effectively a single speed fan and I’d expect the same behavior with the zigbee switch.
