SONOFF
One of the brands with the most affordable devices for home automation, its communication protocol is via Wi-Fi and they are compatible with Alexa and Google Home.

The range Sonoff es a simple and cheap way to home automation. The normal options give us an almost infinite number of combinations, especially if we take into account the timer function and the scenes.

In addition to the usual and well-known relays, we have a large number of lesser known devices, such as switches, outlets, a sensor station, and an RF gateway that allows us to add many more sensors. Although we miss a thermostat and an IR gateway.

For the most daring users, devices can be reprogrammed with one of the firmware developed by the community, and integrate it with other Open Source developments (Home Assistant, your MQTT server).

Lastly, we can also use these devices as a programmable processor(normally the relay) and include it in our electronics and robotics project.
