Remote Power Control


The WebSwitch Plus™ is an IP-controlled remote power strip that’s compatible with any AC device. It features two independent power outlets that can be controlled over an IP network. The WebSwitch Plus can operate worldwide with 100-240V AC and 50/60Hz.

  • 2 Relay-Controlled Power Outlets (10A)
  • 2 Digital Inputs
  • Up to 16 Temperature Sensors

The WebSwitch Plus is ideal for remote power control, remote reboot, and automatic reboot of network devices. Plug in a fan, heater, computer, server, camera, other network equipment—any AC device—for the ability to remotely power devices on or off. Independently control two power outlets using a standard web browser…no special software required.

WebSwitch Plus Features

  • Automatic and Manual Remote Reboot
  • Real-time clock, can automatically adjusts for daylight savings time, sync with NTP server
  • Built-in no-code user interface for easy logic programming
  • Email Notifications
  • Data Logging
  • Added Relay Contact Protection
  • Supports up to 16 temperature sensors or up to 8 temp/humidity sensors

WebSwitch Plus Applications

  • Server Room Monitoring
  • Lighting Control
  • IP Camera Reboot

IoT Relay with Embedded Logic

Many IoT relays require extensive programming knowledge and additional devices (PLCs, Rasberry Pi, etc.) to set up and manage. WebSwitch Plus is a stand-alone unit that comes with a built-in, no-code user interface that allows you to create custom “tasks” using intuitive drop-down menus—no additional software required. The logic is then stored on the devices and can be set up and managed using a standard web browser. Try out one of our control page demos below and see how easy it is for yourself!

Perfect for Server Room Monitoring

Automatic Reboot

The WebSwitch Plus can be set up to send ping requests to servers. If the ping request fails, WebSwitch Plus is configured to then send out another ping request after 10 seconds and if that request also fails, it will automatically reboot the server and internally log the event. It can also send out an email and text alert to an IT tech and administrator.

Monitor Server Temperature

WebSwitch Plus also monitors the server’s temperature. If the temperature exceeds a user-specified threshold, it logs the event and sends an email/text alert to the appropriate personnel.
