A two-way load control system comprises a power device, such as a load control device for controlling an electrical load receiving power from an AC power source, and a controller adapted to be coupled in series between the source and the power device. The load control system may be installed without requiring any additional wires to be run, and is easily configured without the need for a computer or an advanced commissioning procedure. The power device receives both power and communication over two wires. The controller generates a phase-control voltage and transmits a forward digital message to the power device by encoding digital information in timing edges of the phase-control voltage. The power device transmits a reverse digital message to the controller via the power wiring.

A remote control device may be configured to be mounted over the toggle actuator of a light switch and to control a load control device via wireless communication. The remote control device may include a base portion and a rotating portion supported by the base portion so as to be rotatable about the base portion. The remote control device may include a control circuit and a wireless communication circuit. The control circuit may be operably coupled to the rotating portion and to the wireless communication circuit. The control circuit may be configured to translate a force applied to the rotating portion of the remote control device into a control signal and to cause the communication circuit to transmit the control signal to the load control device.

In various embodiments, a hazard detector may be presented. The hazard detector may include at least one hazard detection sensor that detects a presence of at least one type of hazard. The hazard detector may include a speaker, a light, and a motion detection sensor that detects motion in an ambient environment of the hazard detector. A processing system of the hazard detector may be configured to select an illumination state based on a determined status. The processing system may cause the light to illuminate based on the selected illumination state. The processing system may determine a gesture has been performed in the ambient environment of the hazard detector following the light being illuminated based on the selected illumination state. The processing system may output a detail of the status via the speaker corresponding to the illumination state in response to determining the gesture has been performed.

Various arrangements for assessing an installation of a smart home device are presented. An orientation of the smart home device may be analyzed to determine whether the orientation of the smart home device is unsuitable for one or more features of the smart home device to function properly. An indication of whether the orientation of the smart home device is unsuitable may be output, such as by the smart home device using voice or lighting.
