Abstract: An enhanced smart lighting system (ESLS) for use in buildings without neutral wire connections for wall switches. The ESLS entails both a no-neutral wire smart lighting switch (NNWSLS) and a physically separate load adapter. The NNWSLS includes a sensing, control, or communication system (SSCCS) such as integrated WiFi. The load adapter mitigates electrical fluctuations which may be induced in a power load (for example a lightbulb) by the smart lighting switch, particularly when the smart lighting switch is nominally powered off but still has some current flow. The load adapter is an intermediary between the power load and a conventional load receptacle. The load adapter has an integrated dummy load configured in parallel with the power load. The dummy load provides an electrical pathway for low levels of electricity which run through the light socket even when the NNWSLS is set to an “off” configuration.
