To control a light from different spots of your room without any additional wirings follow these few steps:
Imagine you have two iotty in your bedroom, one near the door and one near the bed, they are not connected through wirings but you have a free gang (in our case on the iotty near the bed).
1. Go to Actions of one gang electrically wired to the light (e.g. Door), add a new action and click on Multi-way mode.
2. Here select the gang to be linked to Door (e.g. Bed). Notice that, in our case, Bed is not wired to the light.
3. You can also link more iotty by pressing the + icon.
That’s it! Now Door and Bed are paired.
