It would be nice if Lutron had a Caseta controllable humidity sensing bathroom fan controller. That would permit having a PICO that could turn on all fans in case of requiring fresh air without losing the humidity sensing function. This is/was a building code requirement in Ontario for a while but I think they are now forcussing on HRV installation instead. If you read up on the code it is a bit complicated due to fan CFM requirements...
If that is not possible, an upscale switch like the Maestro line would be nice. I have a couple Leviton switches of this type and they do not fit the Lutron style.
