Problem needed to be defined for electronic problem.

Hi Folks,

I have a door light project, the light is triggered by means of wireless.

Somehow, the light is triggered for no reasons as there are no visitors at the door. It was discovered that whenever the nearby power point is switched on, ie ironing clothes or fan, the light would be triggered.

From what I know is that the power line is shared with the door light device.

The device has relays, voltage regulator,

What is the problem called? how do I solve the problem? The problem is new to me. Please advise. Thanks in advance

Is it a transient voltage or spikes?

Do you have a circuit?
