Why this plug is interesting

Gosund Smart Plug SP111 is one of the most popular smart plugs on the market – and the reason is simple: it combines a low price with wide compatibility. It works with Google Home, Amazon Alexa, Tuya, Smartlife, and IFTTT platforms, so you can easily integrate it into most smart home ecosystems.

The plug communicates via 2.4 GHz WiFi and doesn’t require any hub or gateway – just plug it in, download the GHome app (or Tuya/Smartlife), and within minutes you have smart control over any appliance. With your voice via Google Assistant or Alexa, you can then say, for example, “turn on the living room lamp,” and the plug will take care of the rest.

Key features in practice

The maximum load is 3680 W (16 A), which covers most household appliances – from lamps and fans to heating elements and electric grills. The plug offers real-time energy consumption measurement, so you can find out how much a specific appliance costs to operate. For example, one reviewer on Alza found that their gas boiler (or rather, pump) draws 70 W and costs them almost 2,500 CZK per heating season – something they would never have known without measurement.

In the app, you can set timers, on/off schedules, or use the presence simulation feature – the plug will randomly turn the connected appliance on and off to make it look like you’re home. It includes a child lock and surge protection. The dimensions of 7.9 × 4.8 × 4.6 cm are compact, and the plug does not block adjacent sockets in a multi-gang frame.

After a power outage, the plug will return to its last set state – if it was on, it will turn back on after power is restored. This is practical for things like aquarium pumps or servers.

Even cheaper with AlzaPlus+: 237 CZK

If you have an AlzaPlus+ membership, you get an additional 15% discount on this plug – bringing the final price down to 237 CZK. This is a total saving of 152 CZK compared to the original price of 389 CZK.

What is AlzaPlus+ and is it worth it? It’s Alza’s loyalty program, costing 299 CZK annually (25 CZK per month) or 59 CZK per month for a monthly subscription. The main benefit is free delivery to over 25,000 pick-up points (AlzaBoxy, Zásilkovna, PPL ParcelShop, post office, and others) regardless of the order value. Additionally, you get exclusive discounts on selected goods.

Is it worth it? If you shop on Alza at least once a month and use delivery to pick-up points, the annual membership will pay for itself with just a few orders. The program has a rating of 4.9 out of 5, and 96% of members recommend it. Membership can be canceled at any time.

What users say

On Alza, the plug has a rating of 4.7 out of 5 (16 ratings) and 94% of customers recommend it. Over 50 units have already been sold. Users most often praise its compact dimensions, clear application in Czech, and the ability to measure consumption. They also appreciate that the plug sends notifications during power outages.

Critical remarks primarily concern the dependence on the WiFi signal – if the plug is out of router range, even scheduled timers won’t work (they are not stored locally but require an internet connection). One user solved this by purchasing a WiFi extender. Occasionally, there’s a mention of a non-functional unit upon unboxing – in such a case, we recommend a warranty claim.

When it doesn’t make sense

If you need local control without cloud dependency, this plug will not suit you – all automations require an internet connection. For advanced users with their own Home Assistant, there are alternatives with local API, but at a higher price.

Similarly, if you only have a 5 GHz WiFi network at home, you will need to enable the 2.4 GHz band – the plug does not support other frequencies. However, this is a common limitation of most smart plugs in this price category.

Verdict: who it’s worth it for

The Gosund Smart Plug SP111 is a plug for those who want to simply start with a smart home without major investments. For 279 CZK (or 237 CZK with AlzaPlus+), you get consumption measurement, voice control via Google and Alexa, timers, and compatibility with most platforms. Ideal for controlling lamps, fans, Christmas decorations, or monitoring the consumption of specific appliances. Conversely, if you require local control without the cloud or 5 GHz WiFi, look for alternatives.

Do you use smart plugs mainly for automation, or are you primarily interested in consumption measurement?
