Sonoff have been evolving the industry of home automation and wireless control systems since as far back as 2010, and have produced numerous modules, components and devices for all types of automation and control. Their most popular products include relays and light switches, ranging from basic to advanced functionality, although they have recently moved on to develop entire systems with various control styles, scene setting, as well as timed automation – both in general as well as for specific days of the week, month or year.

One of the more recent products that they’ve developed can be controlled manually on the device or via a smart phone app, and can operate up to four devices via relays. This is ideal for both personal and industrial applications, such as controlling the kitchen wirelessly or setting up automation for a factory-setting. Another interesting addition to their range of products is a relay that operates via GPRS, which is ideal for applications that may be far from urban environments, like farms or log cabins. And with a simple SIM card, you can connect to systems like irrigation, temperature control and access controls via cell phone towers or satellite, to control them directly with your smart phone or similar handheld device.

Sonoff have been steadily working towards connecting both electrical and mechanical devices, machines and systems to the online realm for years now, and their head-start in the industry shows when you compare their products to typical, similar products available to consumers. From light switches to industrial machinery or even the blinds and curtains in an average home, everything will soon be connected wirelessly with the help of reputable brands like Sonoff.
