They are some interesting caveats – of course there’ll be solid objects (such as walls) between the router and my device! Also many devices are made with cheaper components to bring the price down – not high quality components which can support 1,300 Mbps.Įqually, very few of us have internet speeds anywhere near 1,300 Mbps. You don’t have any solid objects between the router and your device (the range of 5 Ghz WiFi drops a lot when going through walls – as I explore in a later section).your smartphone and router should both be able to support 1,300 Mbps, otherwise they couldn’t connect at this speed). All devices within the network should be able to support these internet speeds (i.e. These speeds are, of course, contingent on a few caveats: Related Reading: The Difference Between Kasa, Tapo and TP-Link (Which Is Discontinued?) 2.4 Ghz vs 5 Ghz WiFi, and Why it Mattersĥ Ghz WiFi was announced as part of the 802.11n wireless standard in October 2009, offering speeds up to 1,300 Mbps compared to 450-600 Mbps in 2.4 Ghz. Many early smart plugs only allow for a single device to be plugged into them (they were essentially a pass-through extension socket), but nowadays you can also purchase smart strips – an extension strip with multiple smart-controllable sockets. You will choose this board for instance based on you criteria of connectivity, do you need ethernet? Bluetooth? Wifi? RF? GSM? Sigfox? RF? And then it's capacity to run what you will need it to run such as a REST Api, MQTT server, Socket server and so on.Philips Hue smart plug with physical button on top Usually this gateway board use a slightly bigger and easier to use processor for instance something running able to run Linux as IMX6, IMX8 or raspberry pi or something like that with the proper connectivity and servers one would need. And that gateway board would control your slaves, and all your requests would go through it and the slaves will go through the gateway to get to you. If for some reason you would be requiring more that one MCU then we would go with a "gateway" that will act as the brain of the operation. Or the most commonly use approach at least in R&D is to drive down the cost by using one or several MCU as needed (for instance ESP32 family) and using them as the base board for the sensors and relays and so on, you would use them to get data from the sensor using and switching outputs such as relays or electrovalves. There's two approach, either you buy each individual "smart" stuff ie sensors relays and so on which will include in each of them a MCU + one feature (for instance relays or sensor or electrovalve or whatever). I assume that you are also going to use some sensor and this kind of things. So one would basically connect a relay to a Micro Controller Unit (MCU) with the necessary connectivity to receive the command and pass them to the relay. The command can also be via I2C, for instance with this relay you will have to use I2C to explain to the relay board which switch you want to flip. A relay is exactly a "smart plug" without the smart part, basically a relay is a simple device that will flip a switch based on a command, that command can be simply to put a certain voltage to it's pin (most likely 3.3V or 5V when it comes to IOT). Generally speaking, in such case one would simply use a relay.
