The human presence sensor is so expensive. I bet they are using the same technology of Rada light switch. It's only 1/3 the cost.

So I marry a normal Rada Sensor 5.8hz with a Sonoff door sensor. The magic really happened.

It switch fast. I can adjust 2~8 meters radius. Switch off timing from 8 secs to 10 minutes, by turning pots of course.

The door sensor just relay the message into my Ewelink. I just create a simple scene for my kitchen.

Most rada can me rewire but you need to have some electrical knowledge.

I don't take responsibility for any types damage you may have caused.

Later I will show you another way which is much less electronic knowledge.

Thanks! Take care!
