Customer Questions & Answers
What are the exact dimensions and weight of the module, and what is included in the box?
The module measures approximately 37 mm x 25 mm and is made from a combination of metal and plastic. The package contains one relay module unit only (board with ESP-01s and mounted relay); no cables or power supply are included.
Is it compatible with standard mains voltages and what power requirements does it have?
It works with a 5V DC supply for the module. The relay supports a maximum load of up to 250V AC or 30V DC, with a maximum of 10A. For domestic installations, it requires a regulated 5V DC supply, which is not included.
What programmes or firmware can be used and how difficult is the initial installation?
It is compatible with alternative firmware such as Tasmota, ESPurna and ESPeasy, allowing you to customise its operation. Basic electronics and programming knowledge are required to flash the firmware and configure the WiFi network. It is not plug & play for users without prior experience.
How does this module compare with other smart relays in terms of reliability and operating cycles?
The relay has a rated service life of 100,000 open/close cycles under normal conditions. This places it within the typical range for relay modules in IoT applications, although some industrial-grade models offer more cycles or greater EMC protection. For domestic or DIY applications, the durability is suitable.
Which software is the ESP8266 ESP-01S module compatible with?
It is compatible with software such as Tasmota, ESPurna and ESPEasy, making it easier to integrate into home automation and automation projects.
What is the operating voltage of the WiFi relay module?
The module operates at DC 5V.
What type of devices can I control with this module?
You can control electrical devices such as lights, fans, pumps and other appliances that operate within the maximum load of 10A.
What is the module's maximum WiFi transmission range?
The maximum range is approximately 400 metres in an open environment with a mobile phone equipped with WiFi.
How many switching cycles does the relay support?
The relay has an estimated lifespan of up to 100,000 switching cycles.
