For renters and homeowners with shallow electrical boxes, this smart outlet module fits behind existing switch plates where standard plugs fail.
Mira's cut. This smart outlet module is designed for shallow electrical boxes where standard plugs won't fit. It installs behind your existing switch plate without requiring new wiring.
I keep seeing returns for smart plugs that simply don't fit behind switch plates in older homes, so I focused on the smart outlet module profile that actually clears the shallow box depth.
Check the product photo for the slim profile that slides behind your existing switch plate, the connection type that matches your old switch, and the clearance needed for tight boxes.
How Mira kills a phone accessory
I throw out any listing whose title does not name the phone. Then I keep a short set with a real listing photo.
- The Amazon title names this phone, not last year’s.
- Listing photo is from that product page.
- MagSafe / USB-C / bump cutout is in the title if the pick needs it.
- Public rating exists when Amazon shows one — not a fake lab score.
If the title is for a different generation, I would not open the box. Check live price on Amazon.
SONOFF MINIR4 10A Smart WiFi Extreme Wireless Light…
The SONOFF MINIR4 is a universal DIY module rated for 10A, designed for smart home automation where you need to retrofit existing wiring without replacing the entire switch mechanism. Its compact form factor is the primary differentiator here, as it is built to be installed in tight spaces where standard plugs cannot physically reach.
In the product photo, verify the depth of the module body against the depth of your electrical box. If your box is shallow, this unit is the candidate to check, but you must ensure the wiring terminals have enough clearance to connect without forcing the plate back into the wall. The lack of a protruding plug face is the key visual cue that this fits behind your existing switch plate.

Steren 2.4GHz Smart Wi-Fi 2 Plug Outlet, Compatible with Alexa &…
The Steren SHOME-100 is a 2.4GHz smart Wi-Fi plug that offers remote app control and compatibility with Alexa and Google Assistant. It is a standard form-factor device that occupies the outlet space directly, meaning it requires a clear, unobstructed receptacle to function.
Look at the photo to see the full height of the plug body extending from the wall. This is the profile that fails in shallow boxes or behind existing switch plates because it physically blocks the area. If you are trying to fit a device behind a plate, this unit is the wrong shape, as it is designed to sit in front of the outlet, not inside the box.

Shelly Pro 1
The Shelly Pro 1 is a 1-channel smart relay switch that supports both Wi-Fi and LAN connections, acting as a Bluetooth gateway and compatible with major voice assistants. It is a DIN-rail or screw-mount module designed for integration into home automation systems rather than direct plug-in use.
Check the photo for the mounting holes and the size of the relay body. This is a component that goes inside the electrical infrastructure, so you are looking for a device that can be secured to a DIN rail or screwed into a junction box. It does not have a plug face, so the fail state here is not about depth, but about whether you have the space to mount a relay module rather than a plug.

Outlet Wall Mount for Blink Sync Module 2 with Built-in Charger &…
This is a 2-in-1 space-saving bracket and holder for the Blink Sync Module 2, featuring a built-in charger and power adapter. It is a mounting accessory designed to keep the Blink module off the floor and out of the way, using a no-drill plug-in holder mechanism.
In the photo, focus on the bracket's footprint and how it attaches to the outlet. This is not a smart plug itself, but a holder for a specific device. The fail state is if you are looking for a smart switch to control lights; this is a power and mounting solution for a security camera hub. It occupies the outlet to power the Blink module, not to provide smart control for other devices.

Zooz 800 Series Z-Wave Long Range Smart Plug ZEN04 800LR
The Zooz ZEN04 800LR is a Z-Wave Long Range smart plug that requires a hub such as the Z-Box, Home Assistant, or Hubitat to function. It is part of the 800 Series, which is known for extended range and reliability in Z-Wave networks.
Look at the photo to assess the plug's bulk and the position of the Z-Wave antenna. This is a standard plug-in device, so it will not fit behind a switch plate. The fail state is if you need a low-profile module; this unit is designed to sit in the outlet, and its size is typical of a smart plug, not a retrofit module. It is the wrong form factor for shallow box installations.

Kasa Smart Outdoor Smart Plug KP400, Smart Home Wi-Fi Outlet with…
The Kasa KP400 is a smart outdoor plug with two sockets, designed for use with Alexa, Google Home, and IFTTT without a hub. It is built to withstand outdoor conditions, with a sunshade to protect the electronics from direct sunlight.
The photo shows a bulky, dual-socket design with a weatherproof housing. This is the profile that fails in indoor shallow boxes because it is too large and not designed for retrofitting. It is an outdoor-specific device, so using it indoors behind a switch plate is not only a fit issue but a design mismatch. It occupies the outlet and adds significant depth, making it unsuitable for tight spaces.
Philips Hue Smart Plug, White – 2 Pack – Turns Any Light Into a…
The Philips Hue Smart Plug is a white, 2-pack device that turns any light into a smart light, controlled via the Hue App and compatible with Alexa and Google Assistant. It is a standard smart plug designed to integrate with the Philips Hue ecosystem.
Check the photo for the plug's height and the position of the Hue logo. This is a standard plug-in device, so it will not fit behind a switch plate. The fail state is if you are looking for a module that goes inside the box; this unit sits in the outlet and requires a clear receptacle. It is the wrong form factor for shallow box installations, as it is designed to be visible and accessible for plugging in lights.

4 Pack Smart Plug, Compatible with Alexa&Google Home, WiFi Timer…
This is a 4-pack of smart plugs compatible with Alexa and Google Home, featuring Wi-Fi timer socket functionality. It is a multi-pack designed for setting up multiple smart outlets in a home, with a focus on timer and scheduling features.
Look at the photo to see the size of the individual plugs. This is a standard plug-in device, so it will not fit behind a switch plate. The fail state is if you need a low-profile module; this unit is designed to sit in the outlet, and its size is typical of a smart plug, not a retrofit module. It is the wrong form factor for shallow box installations, as it occupies the outlet space directly.

Emporia Vue 3 Home Energy Monitor – Smart Home Automation Module…
The Emporia Vue 3 is a home energy monitor and smart home automation module that provides real-time electricity usage monitoring and power consumption metering. It is designed to track energy usage for solar and other home automation needs.
In the photo, verify the size of the monitor unit and the number of ports it occupies. This is a multi-port energy monitor, so it is a large device that requires multiple outlet spaces. The fail state is if you are looking for a single, slim module that fits behind a switch plate; this unit is a bulky monitor that sits in the outlet and provides data, not just smart control. It is the wrong form factor for shallow box installations, as it is designed to be a visible monitoring hub.
