This disclosure describes systems, methods, and apparatus for wireless and non-line-of-sight commissioning of smart devices. Smart devices can broadcast a first radio message that is detected by an ID tool during commissioning. The first radio messages can be unique to each device, such that the ID tool can send a second radio message addressed to a select device, the address based on the first radio message from the select/addressed device. The addressed device can respond to confirm the identity and location of the addressed device. The ID tool can then send a third radio message with a registration request command, again addressed to the selected installed device. In response, the selected installed device can enter a registration request mode and transmit an identification to a commissioning system, whereby that device's identity is now know to the system and can be wirelessly controlled.

This disclosure describes systems, methods, and apparatus for determining a relay delay for a relay of a relay device used to switch AC power to and from a load. The relay delay can be pre-determined as a model or polynomial including variables for temperature and age, such that the switching instructions can be sent to the rely a relay delay before a zero crossing of the AC signal that the relay is switching, and where the relay delay accounts for temperature and age of the relay in real time or near real time.

This disclosure describes systems, methods, and apparatus for an LED driver circuit capable of responding to dimmer signals from three different types of dimmers: a phase cut dimmer, a dedicated dimmer (e.g., 0-10V dimmer), and a button dimmer. The processor can include inputs for each of these dimmer types, and can be configured to determine which of the three types of dimmers is controlling the LED driver circuit, and determine which dimming signals to respond to when more than one dimmer type is trying to control the LED.

Various systems and methods facilitate internal communication within a lighting module as well as intercommunication among lighting modules over an external network. The network may be a conventional network managed by a central network controller or may be an ad hoc or 'mesh' network&#x2014;i.e., a scalable network architecture in which any lighting module is a node that can communicate with any other module or network-connected device.

Communication with lighting units over a power bus

An illumination system detects a peak value of a voltage of a transformer supplying an LED module by analyzing the current value of the voltage and an on-time of the voltage. Based on the detected peak value, a property of the illumination system is adjusted.

Transformer voltage detection in dimmable lighting systems

A bleed circuit is applied to a transformer based on a bleed-on time and a bleed-off time determined by monitoring an output voltage waveform of the transformer.
