This is a quick temporary solution to deter prowling cats. The actual Cat Scarer is back in the workshop waiting for a smaller motor to be delivered because the present motor is from a hand vac cleaner is a over kill and (even with short duty cycle) draws to much from the AGM 12V / 3.7A battery.

Uses a Alexa/Smart Life compatible Wi-Fi Switch.

One of my favourite wi-fi devices.

The PCB is mounted in a small food container and the electrical junction box has the 240V/10A relay contacts wires coming in terminating the input 240V plug top cable and output line socket cable.

The whole thing looks like this.
