Abstract
In-wall dispensing modules, such as room freshener modules, can reside in a housing with a cover that can be opened to access an interior space of the module to, inter alia, replace used containers. The housings are configured to reside inside a wall of a room. The front cover can be a planar cover that is flush, slightly recessed or slightly protrudes from the wall. The housings can be a “custom” housing size and/or may be configured to occupy a single gang box or a compartment of a multi-gang junction box. The modules can include an actuator that can cause a canister to emit scented fluid at desired intervals and/or on-demand. The modules can have a User Interface (UI) wireless and/or wired connection to a whole-house “smart” system.
