Hi @robf22!
I urge you to check out our “Out of Stock” Thread where we keep updates on exactly what you asked for - when products are coming back into stock.
As you will be able to see in that thread, Fan + Light is slated to not return until early 2022 due to shortages in the supply chain. We are also currently having an issue with some technical aspects of the switch (see THIS thread) so we have currently taken the remaining units down that we do have. Once we have resolved the disconnection issue we will have about 50 remaining units to put up for sale.
We do pre-orders for almost all products, but only when we know we have set dates from our manufacturer, as they often change things around on us with little to no warning. January is a bit too far away still for us to open a pre-order for fan switches.
Hope this helps!
