Product description: Sonoff SPM-4Relay - 4-channel smart relay module 20A - WiFi - Android / iOS application
SPM-4Relay is an advanced relay module from Sonoff designed to monitor and manage electricity consumption in real time. Each of the four channels of the module supports a load of up to 20 A , which allows for safe management of high-power devices. The module works with SPM-Main , using the RS-485 interface, which guarantees stable data transmission over long distances. Thanks to integration with the eWeLink application, the user can remotely control each channel, check energy consumption and set overload thresholds for individual devices. The SPM-4Relay module is easy to install thanks to the possibility of mounting on a DIN rail , which allows for quick and aesthetic implementation in any electrical installation.
Attention!
The relay module only works with SPM-Main. It must be purchased separately.
Sonoff SPM-4Relay - 4-channel smart relay module 20 A - WiFi - Android / iOS app.
SPM-4Relay is an advanced relay module designed to monitor and manage electricity consumption in real time.Special features of the relay module
- 4 independent channels: each channel supports a maximum load of 20 A
- RS-485 communication: stable data transmission with the SPM-Main main module
- Overload protection : automatic disconnection of the circuit if the set parameters are exceeded
- Remote control: integration with eWeLink app allows you to control each channel and monitor energy consumption
- Easy installation: DIN rail installation option for quick and aesthetic implementation
eWeLink App
SPM-4Relay can be easily connected to the eWeLink app, which is the control center of the device. After a quick setup process, users gain full control over the switch via their smartphone. The app allows you to remotely turn on or off connected devices, monitor real-time energy consumption, and view historical data. Furthermore, eWeLink allows you to set work schedules, create automation scenarios, and receive notifications when energy consumption exceeds set limits. This allows users to effectively manage their energy consumption no matter where they are, with the only requirement being internet access.
