One or more techniques and/or systems are provided for providing power and/or communication to a device, such as a dispenser, a flush valve of a bathroom device, a hygiene opportunity measurement device, a hands free faucet, etc. For example, a mounting system comprises a mounting plate that may attach to a structure, such as a wall. The mounting plate may comprise a mounting connector that may be configured to mate with a device connector of the device to establish a connection. Power may be provided to the device through the connection. A communication may be provided for the device through the connection. For example, the device may send current device statuses, usage metrics, and/or other information to a remote source. The remote source may send instructions, data collection requests, functionality changes, and/or other information to the device.

A method and apparatus for obtaining a product chemistry from a product and a fluid is provided. A product is housed within a dispenser. A fluid is introduced through a manifold diffuse member having a plurality of ports. A cover is positioned adjacent the manifold diffuse member and includes a plurality of ports. The cover is able to be adjusted, for example, by rotating the cover, to align and un-align the manifold diffuse ports and the cover ports. This adjustment controls the flow characteristics of the fluid through the manifold diffuse member and cover to control the characteristics of the fluid in contact with the product. The adjustment of the cover to control the flow will provide a generally consistent concentration and erosion rate based upon known relationships between a characteristic of the fluid and the flow of the fluid in relation to the product.

A method may include receiving, from a first restroom appliance of a plurality of restroom appliances arranged in an environment, environmental data comprising an ambient light level, the first restroom appliance comprising a sensor configured to detect the ambient light level and a communication device configured to transmit the ambient light level; determining, with at least one controller, an adjusted infrared pulse frequency based on the ambient light level received from the first restroom appliance; and modifying, with the at least one controller, an infrared pulse frequency of a second restroom appliance of the plurality of restroom appliances based on the adjusted infrared pulse frequency.

A system may include a toilet arranged in an environment; a proximity sensor arranged in the environment and configured to detect proximity data associated with a proximity of a person to the toilet; and at least one controller configured to: determine, based on the proximity data associated with the proximity of the person to the toilet, whether the person is standing in front of the toilet or sitting on the toilet; determine, based on whether the person is standing in front of the toilet or sitting on the toilet, an adjusted amount of water for a flush of the toilet; and modify, based on the adjusted amount of water for the flush, an amount of water used during the flush of the toilet.

A locking assembly for a dispenser may include a locking component and a barrel. The locking component is movable between (i) a first position configured to lock a cover of the dispenser, and (ii) a second position configured to unlock the cover. The barrel is rotatable between (i) a first barrel position configured to resist movement of the locking component, and (ii) a second barrel position configured to permit movement of the locking component. The barrel defines a barrel opening configured to receive a key or a push button. A dispenser including a dispenser plate and a cover may further include the locking assembly. The dispenser defines an interior closable with the cover. The cover is movably coupled to the dispenser plate. The locking assembly releasably secures the cover to the dispenser plate.
