The reason im am asking is, i know i can wire up the smart module to constant unswitched feed (wired that way from the switch box) but the only way from then on to disconnect the power (to do. Reset or something like that) is to go to the fuse box. Is there any way to wire up to the smart dimmer switch where when pulling the disconnect tab on the smart switch, it also disconnects the smart module? So, is there a setting on the switch to have the switched output be set to constant regardless of any other setting or automation?
No, you cannot wire the load of a dimmer switch to feed power to a fan, regardless of whether it’s going through a fan/light module or not.
What you could do if you don’t want to have to flip the breaker to restart the fan module is to put a smart relay on the unswitched line going to the fan module (in the fan canopy). Basically the smart relay would become your power flip option for the fan module. I’m not sure if you’ll have room in the canopy for both of those, but that’s the correct way to wire it if you need a disconnect for the canopy module.
Bummer. I thought there might be a way to use the smart dimmer as a smart relay.
Nope. All of the power always goes through the dimming circuitry.
That you again. It is only a problem when it loses connection and requires a reboot. I will continue to flip the breaker 
. This does not happen often, and only one time did I have to go back up and pull it out for a factory reset.
If you use an On/Off switch in “smart bulb” mode it will do what you want it to do. The On/Off switch can handle the fan and bulb loads of the fan/light canopy module. The power will pass through the On/Off switch allowing you to cut power to the fan/light canopy module using the air-gap. The switch paddles will have no impact on the power going to the canopy module (it will always be on).
You can use an automation or matter binding to link the switch to the canopy module.
