Frequently Asked Questions
Q: Does the ESP8266 ESP-01 WiFi relay module require any programming to set up?
A: No! This ESP-01 relay module is designed to be plug-and-play. It comes pre-configured and ready to use straight out of the box — simply connect it to your 5V power supply, pair it with your WiFi network via your smartphone, and start controlling your devices remotely. No coding experience is required.
Q: What is the difference between the 1-way and 2-way relay module versions?
A: The 1-way relay module (32.1 × 50.7 mm) controls a single circuit or device, making it ideal for switching one appliance on or off. The 2-way relay module (32.1 × 33.7 mm) controls two independent circuits simultaneously, giving you more flexibility for multi-device automation projects — both are controlled wirelessly via the ESP-01 WiFi module.
Q: What is the maximum WiFi control range for this relay module?
A: In an open outdoor environment, the ESP-01 WiFi relay module can maintain a stable wireless connection of up to 100 metres. Indoor range may vary depending on walls, obstacles, and interference from other wireless devices.
Q: Is this relay module compatible with Arduino or Raspberry Pi projects?
A: Yes. The ESP8266 ESP-01 relay module uses low-level triggering and standard 5V DC logic, making it compatible with Arduino, Raspberry Pi, and most other popular microcontroller platforms used in DIY electronics and IoT projects.
