Seeed Studio has recently launched a 2-channel Wi-Fi AC relay built around the XIAO ESP32C3 WiFI and Bluetooth module. The device is a simple WiFi relay module that can control two independent 100-240V AC appliances and is designed to be compatible with both Home Assistant with ESPHome firmware flashed by default. The device also features a built-in BL0942 power meter with a maximum load capacity of 2400W at 240V for real-time and historical energy consumption monitoring. These features make this device suitable for applications such as energy tracking and remote control of appliances. Seeed Studio 2-channel Wi-Fi AC relay specifications: MCU – XIAO ESP32-C3 with ESP32-C3 WiFi 4 and Bluetooth 5.x RISC-V microcontroller, USB-C port (unused here) Wireless connectivity – 2.4GHz Wi-Fi Relay channels – 2 independent channels Power Input terminals – Neutral (N), Live (L) Input voltage – 100-240V AC, 50/60Hz Output terminals Channel 1: N1 (Neutral), L1 (Live) [...]
