Sonoff Basic R2

The Sonoff Basic R2 is an excellent entry point for anyone beginning their home automation journey. While it is a basic switch, it delivers all the essential connected features you would expect — including scheduling, inching, and remote control via the eWeLink app. It is also the most affordable smart switch in the Sonoff range, making it an attractive option for those looking to experiment without a large upfront investment.

However, it’s important to note that the Basic R2 is rated for a maximum load of 10A. While this is sufficient for most small appliances — and many kettles (though you should always check the rating of your specific appliance) — it is not suitable for high-powered devices such as geysers or large heaters. The Basic R2 is best used with low to medium-power appliances.

Another thing to keep in mind is its physical size—about the size of two matchboxes. That’s compact enough for many setups, but it can be a bit tricky to fit into tight spaces or smaller electrical boxes.

Also, while it gets the job done for basic automation, it doesn’t include some of the advanced features you’ll find in higher-end Sonoff models. For example, the Sonoff Mini R4 offers extras like “magic switch” functionality and support for external triggers—handy if you need more flexibility.

In short, if you need a simple, affordable way to bring automation to basic appliances, the Sonoff Basic R2 is a great choice — just be mindful of its limitations.
