Espressif, the Chinese powerhouse, dominates the world of IoT devices, particularly in office environments. Known among geeks for the wildly popular ESP32 chipset, Espressif has become a staple in creating simple Home Assistant devices like ESPhome and ESPresense. However, beyond the DIY community, Espressif leads the market in professional and enterprise hardware as well. Many internet-connected devices, including EV chargers, rely on Espressif chipsets… And I wouldn’t be surprised if a lot of them use the very well documented, super popular, and easily available ESP32 as well.
In a building in Ghent, almost 30 Espressif devices are connected to our network. Our software identifies the manufacturer via MAC addresses, indicating the network interface runs on Espressif hardware, though the overall hardware might be produced by other companies. For example, our software reports a generic Apple name for iPhones, iPads, and MacBooks.
A significant portion of these devices are EV chargers, but the diversity is notable. Some are smart lockers for the fitness center, others are various sensors, and a few remain unidentified. While this information might not be very useful for property owners or facility managers, it’s always beneficial to know this metadata. And we, at FlatTurtle, kinda geek about this. 😉
