Just like “Three Shells” Demolisher, This Created by three bright yellow network monitors [David Chatting] It may be difficult to wrap your head around at first glanceThey do not have any obvious controls, and their constantly changing indicators are abstract to say the least. But once you understand how to read them and understand the unique software library he developed to make them work, we bet you will want to add something similar to your own network.
The first configuration of the display is done through the Yo-Yo WiFi Manager library. It is a captive portal system, which is different from the popular WiFiManager library, but in this case, it can push the network configuration to multiple devices at once. This MIT licensed library, Which [David] Has been developing [Mike Vanis] and [Andy Sheen], It should be very helpful for anyone who wants to quickly connect multiple sensors online.
We are also very interested what [David] Call approximate libraryThis allows the ESP8266 or ESP32 to use WiFi signal strength to determine when it is close to a specific device, and from there determine its IP and MAC address. In this project, it is used to pair the “device wheel” monitor with its intended target.
Once locked, the black and white wheel of the display will rotate when it detects traffic from the paired device. We think this library may have some very interesting applications in the field of home automation. For example, it will allow a handheld remote control to control any device that the user happens to be closest to at the time.
Whether you follow the instructions and copy the meter as is, or just use an open source library that supports them in your own project, we think [David] There are quite a few gifts for the community in these unique gadgets.
