Introduction
The SONOFF Wall Switch Enclosure (E1GS) module transforms the MINIR4, MINIR4M and ZBMINIR2 into a fully functional smart switch, expanding your installation options. While these modules can be used with a traditional switch, using it with the E1GS enables a more affordable and streamlined smart switch setup. Additionally, the E1GS simplifies the installation process by helping to keep wiring neat and organized, making your smart home upgrade easier and cleaner.
This guide will focus specifically on how to use the E1GS. For detailed information on installing the SONOFF MINIR4, MINIR4M and ZBMINIR2, please refer to the dedicated installation article.
What You´ll need?
- 1x SONOFF MINIR4
- OR 1x SONOFF MINIR4M
- OR 1x SONOFF ZBMINIR2
- 1x SONOFF E1GS
- Electric tools
What is the E1GS
The new SONOFF product, the smart wall switch enclosure E1GS, transforms the SONOFF MINIR4, MINIR4M or ZBMINIR2 DIY modules into a fully functional smart switch. This product consists of two main parts:
- Front frame
- Adapter with a slot for the DIY module and connection contacts
On the back of the E1GS, there is a slot to insert the modules (MINIR4, MINIR4M or ZBMINIR2 along with a clear description of the connection terminals:
-
L – Live wire
- N – Neutral wire
-
Lout – Up output
-
S1 and S2 – Switch wires
How to install

WARNING:
|
For this example, we are using the SONOFF MINIR4, but the installation process is the same if you are using the MINIR4M or ZBMINIR2.
As you can see, the wiring diagram between the MINIR4M and the E1GS is essentially the same, with one important difference. When using the E1GS, it is no longer necessary to connect two wires from the S1 and S2 terminals of the module directly to the switch. Instead, the S1 and S2 contacts on the module are connected internally to the E1GS terminals. This greatly simplifies the installation process.
In this image, you can see the terminals S1/S2 inside the E1GS where the module is inserted.
Once the MINIR4M module is inserted into the E1GS, the S1 and S2 terminals are immediately connected, so there’s no need to worry about wiring them separately.
Once the module is inserted, proceed with connecting the MINIR4M wires. The installation is the same as a standard MINIR4M retrofit switch setup, with one key difference: when using the E1GS, you don’t need to connect wires from the module’s S1 and S2 terminals to the switch. The E1GS automatically handles these connections.

WARNING: Although it is not necessary to connect wires from the module to the E1GS, once the contacts are inserted into the MINIR4, MINIR4M or ZBMINIR2 module, you MUST tighten the S1 and S2 screws after fitting to ensure a secure connection. All the terminals must be tightened before closing the installation. |
Finally, simply place the wires inside the box and secure it to the wall using the screws provided in the package.
The next step is to tighten the screws and fix it to the wall.
The end result is a smart switch with an elegant and functional design.
Conclusion
The SONOFF Smart Wall Switch Enclosure E1GS offers a practical and efficient solution to transform the MINIR4, MINIR4M or ZBMINIR2 module into a fully functional smart switch, simplifying the installation process and reducing wiring complexity. By integrating the S1 and S2 connections internally, it eliminates common wiring challenges, making smart home upgrades more accessible and user-friendly. Whether you’re a professional installer or a DIY enthusiast, the E1GS enhances your SONOFF setup with greater convenience and reliability.
