The use of smart relays (some products are also called "modules") allows you to use ordinary switches, so the selection of switch appearance is more flexible. However, because this adds an extra device to the circuit, the difficulty of maintenance may increase, and it also tests the reserved space in the electrical box or switch embedded box.

Although the operating concepts of smart relays are similar, the hole designs of different brands vary greatly. Therefore, we will select several major brands and introduce a smart relay suitable for lighting control. You can find the product that suits you from the case below.
Products such as smart relays are particularly suitable for placement near the ceiling octagonal box because most of them involve wiring changes. Therefore, the following example uses placement on the ceiling as an example. If you want to place it in a switch box, that is also possible, but remember to pay attention to the space inside the switch box.

Shelly 1PM Mini Gen3
Shelly's products are quite diverse. Different products can correspond to different situations, and there are many products that can be used for lighting control. Here we will demonstrate the relatively simple 1PM Mini.
ℹ️ You can basically cut as many as you want under the ceiling. If you don't know how to connect it, you can look back.EP 0 Understanding Traditional Lighting Control Circuits".

The above is the wiring method of the lighting control circuit of the smart relay! The ones recommended above are all zero-live versions, because since relays are used, it should be relatively easy to get the neutral line on the ceiling, so I will not recommend single-live relays here~
