Hey @walterdb! It sounds like this will be best brought up with your electrician. To cover all bases, I recommend checking on any light settings such as sensitivity and duration. Please also ensure there is nothing close by that might be constantly triggering the lights, and that you are not linking this device with another that might be toggling lights.
If the lights are on constantly, even during the day, this would be indicative of installation or power related concerns. If the above steps do not help to resolve your concern with the lights, the best next step would be to inquire with your electrician. Feel free to let us know how this goes!
