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 toilet tank washbasin and faucet system that rests on top of a toilet tank is described by way of example. The faucet dispenses water intended to fill the toilet tank over a drain that leads into the toilet tank. The faucet is useful to a person for washing their hands with the water dispensed from the faucet to advantageously provide a second use of the water before flushing down the toilet. Generally described is a basin that sits atop an open toilet tank. A faucet having a nozzle end is attached to the basin via a keyed member that a) positions the nozzle end over a drain in the basin and b) prevents rotation of the faucet when attached to the basin, the drain leads into the toilet tank. Water is provided to a flexible tube that attaches to a bowl refill tube. The flexible tube extends through the faucet and terminates essentially at the nozzle end.

A toilet tank top cover, including: a compartment for containing a liquid detergent; and a dispenser, for manually dispensing a dose of the liquid detergent from the compartment downwards into a toilet tank, being covered by the toilet tank top cover, thereby utilizing a large space of the compartment, as being adapted to a large length and a large width of the toilet tank, for dispensing the liquid detergent therefrom.
