In response to this, Espressif has based its smart switch on ESP32-C3, which supports Wi-Fi and Bluetooth 5 (LE) connectivity, while also combining industry-leading radio frequency and low power-consumption, along with enhanced security features and memory resources. This increases the cost and complexity of such solutions, while also limiting, to a certain extent, the development of these smart switches any further. Therefore, most smart switches use Zigbee and Bluetooth LE networks which, however, require additional configurations. On a different note, due to the high power-consumption of most Wi-Fi chips, it is difficult to ensure that the power consumption of a smart switch is less than 50 uA, for example, when a lamp connected to the circuit is turned off hence, an abnormal flickering of the lamp may occur. However, Espressif’s smart switch does not need a neutral wire, which can help users greatly reduce their installment costs. That’s why rewiring is the most common approach to replacing traditional switches with smart ones. Many smart switches on the market often require a neutral wire, but most traditional switches in older houses do not include one. Espressif’s smart switch also combines low power-consumption with reliable and secure Wi-Fi connectivity. This solution upgrades traditional switches to smart switches, with no need for rewiring or configuring a gateway in the process. Espressif has been at the forefront of the IoT revolution, with our latest contribution being a smart switch based on the ESP32-C3 SoC. Consumers’ attention has shifted towards an ever-increasing number of smart devices that can make people’s lives more comfortable. The present-day popularity of the Internet of Things has brought smart-home applications to the spotlight.
