Sonoff SPM-4Relay smart switch

Sonoff SPM-4Relay smart switch, which, in combination with the SPM-Main module (sold separately), enables measurement of power consumption. It can handle 4 independent channels, and also allows you to use overload protection to protect your devices from damage. At the same time, the product is very easy to install - you can easily mount it on a guide rail.

Multiple applications

Sonoff SPM-4Relay switches will prove useful in many applications. For example, they will allow you to check how much electricity your tenants use per month, as well as the energy consumption of a shopping center or office. The product will also prove useful in a cryptocurrency mine or server room. Thanks to the overload protection function, you will reduce the risk of damaging your devices.

Reliable connection

How does it all work? Sonoff gives you the ability to connect your devices. The SPM-Main switch communicates with the cloud using Ethernet or Wi-Fi connectivity. This allows it to control the SPM-4Relay switches via RS-485. As a result, stable data transmission over long distances is ensured. Don't be afraid of connection problems!

Power consumption measurement

Do you want to be able to control the power consumption in each room in the office? Or maybe you want to check how much power your tenants are using? Sonoff SPM-Main and SPM-4Relay switches will make it possible for you! The devices allow you to accurately measure energy consumption, and convenient access to information is provided by the eWeLink application. You no longer need to leave the house to check power consumption - just reach for your phone!

Overload protection

You can also increase security in your server room or cryptocurrency mine with the help of Sonoff brand switches. The product offers an overload protection function. Just activate it, and the connected equipment will automatically shut down when the current parameters reach the values indicated in the application. You can also use the load delay function.

4 channels per switch

Each SPM-4Relay switch offers 4 independent channels with a maximum load of 20A each. What's more, one SPM-Main can control as many as 32 SPM-4Relay switches. This means that one main module will handle up to 128 channels! This is a perfect solution for a block of apartments, for example, where it will allow you to check the energy consumption of tenants of rented apartments. Connect the switches together and enjoy the results!
