PLM-1 and Lighting Control (anglais seulement) |
|
PLM-1 enables lighting control in existing homes or buildings. Replace wall switches and dimmers with PLC communicating switches or dimmers. These devices receive PLC commands that turn them on or off, set them at given light levels, etc. Different controlling devices send commands to PLC-enabled wall switches, from HA controllers or manual keypads to PCs. A standard Web browser may also be used to control and program lighting functions over the Internet.
If these products allow bidirectional communication, switches and dimmers can report the power level of the load under control (on/off, actual level, etc.) or any other internal variable. Set up your devices in predefined groups and control each group with a single command, e.g., group exterior lighting.
When you activate your wall switches, they too can transmit PLC messages. You could, for example, push a switch before leaving home and set the whole house in unoccupied mode, turning off all lights, triggering the security system, activating random light patterns to simulate your presence, adjusting temperature set points to save energy, etc.
Don't tear down walls and install new wires: PLM-1 efficiently implements lighting control and doesn't require new wiring
