Shelly Power Strip 4 vs Shelly Plug S: Which Smart Power Solution Fits Your Home?

When setting up a smart home, managing power distribution efficiently is key. Two popular options from the Shelly ecosystem are the Shelly Power Strip 4 and the Shelly Plug S – but they serve different purposes. The Power Strip 4 offers multiple outlets in one compact unit, while the Plug S gives you individual socket control with energy monitoring. This comparison will help you decide which solution fits your needs, whether you're automating a desk setup, a home office, or a living room.

Both devices are designed to bring intelligence to your electrical devices, but their form factors and features vary. We'll explore critical aspects like installation, compatibility, energy monitoring, and control options. By the end, you'll know whether a centralised power strip or a set of smart plugs is the smarter choice for your home automation journey.

Design and Physical Setup

The Shelly Power Strip 4 is a traditional power strip form factor with four independently controlled outlets, plus two USB charging ports. It plugs directly into a wall socket and can be placed on a desk or floor. The Shelly Plug S, on the other hand, is a single smart plug that replaces an ordinary wall outlet adapter. It’s compact and designed to fit behind furniture or in tight spaces. For applications requiring multiple outlets in one spot, the Power Strip 4 is more convenient, while the Plug S excels when you only need to automate a single device.

Installation differs as well. The Power Strip 4 is a plug‑and‑play device – just plug it in and connect via Wi‑Fi. The Plug S is similarly simple: insert it into a wall socket, then plug your appliance into it. Both support the Shelly Smart Control app and voice assistants. However, if you need to control several devices in the same area, managing multiple Plug S units can become cumbersome compared to a single Power Strip 4 with individual outlet control.

• Tip: For a desk with a monitor, lamp, and phone charger, the Power Strip 4 consolidates control into one unit. For a standalone coffee maker, a single Plug S is more discreet.

Power Management and Energy Monitoring

Energy monitoring is where the Shelly Plug S truly shines. The Shelly Plug S MTR Gen3 Black provides real‑time power consumption data, allowing you to track energy usage per device and set automation rules based on power draw. The Power Strip 4 also measures total consumption, but it does not monitor individual outlets separately – you only see the combined load. For detailed insights into specific appliances, the Plug S is superior.

If you need to control multiple high‑power devices, consider a relay‑based solution. The Shelly Plus 1 x2 is a dual relay that can switch two independent circuits, ideal for fixed installations like lights or pumps. While not a plug or strip, it offers robust 16A per channel and seamless integration with your smart home system. This is a great alternative when you want to embed intelligence behind existing sockets or switches.

• Comparison: Plug S – per‑device monitoring; Power Strip 4 – total load monitoring only.

Control and Automation Flexibility

Both devices support scheduling, scenes, and remote control via the Shelly app, but the Power Strip 4 offers a unique advantage: individual outlet control with physical buttons on the unit. Each outlet has a manual override, which is handy when you need to reset a device without using your phone. The Plug S lacks a physical button, relying solely on app or voice commands. However, the Plug S’s compact size makes it easier to integrate into existing setups without a visible power strip.

For advanced automation, the Power Strip 4 exposes each outlet as a separate device in Home Assistant, Google Home, or Alexa, giving you granular control. The Plug S works similarly but as a single device. If you have many devices to automate, using multiple Plug S units can clutter your home network – each one is a separate Wi‑Fi client. The Power Strip 4 uses a single connection for four outlets, reducing network overhead.

• Pro tip: Use the Power Strip 4 for entertainment centres where devices are grouped. Use the Plug S for appliances like humidifiers or space heaters that need per‑device monitoring.

Which One Should You Choose?

The decision boils down to your use case. Choose the Shelly Power Strip 4 if you need multiple smart outlets in one location, prefer physical buttons, and want to minimise Wi‑Fi devices. Choose the Shelly Plug S if you require per‑device energy monitoring, need to automate a single appliance, or want a discreet solution that doesn’t sit on the floor. For permanent installations with higher power loads, consider the Shelly Plus 1 x2 as a relay alternative.

Both products are reliable, easy to set up, and fully compatible with the Shelly ecosystem. If you start with one Plug S and later expand, you can always add a Power Strip 4 for concentrated areas. No matter your choice, you’ll enjoy remote control, scheduling, and integration with your smart home system.
