Outdoor motion sensor light stays on — Barcelona, Catalonia
An outdoor motion sensor light that stays on continuously instead of cycling off after a set time wastes electricity and loses its purpose as a security deterrent. The usual culprits are a misadjusted sensitivity dial picking up heat from HVAC vents or passing traffic, a stuck relay inside the fixture, a faulty sensor module, or the fixture being left in manual-on mode after a power flicker. An electrician can recalibrate the sensor, replace the photocell or sensor module, and verify the wiring is correct.
Waarom dit veel voorkomt in Barcelona
Many pre-1990 Eixample and Gràcia buildings still carry undersized or outdated wiring that fails current REBT standards, and panels frequently lack the residual-current devices required since 2002. Lifts retrofitted into stairwells and patios add complex shared electrical infrastructure, and any installation work requires a GVA-equivalent Catalan completion certificate filed through the Generalitat.

- Sensitivity and timer dials have no visible effect when adjusted
- Photocell (dusk-to-dawn sensor) doesn't prevent the light from running during daylight
