The WiFi Wireless Gateway (WiFi Gateway) receives messages from the Wireless sensors and sends them to the PrivateEyePi or JemRF Monitoring service. This eliminates the need for a Raspberry PI computer and all that extra overhead. The Gateway provides an easy to use tool to get your wireless sensors online free of configuring and programming a computer first.

The WiFi Gateway is in the same physical case as the current WiFi IoT Sensors.

  • Follows the same setup process as our WiFi IoT Sensors to connect to the local WiFi.
  • It has option to send Celsius to Fahrenheit readings.
  • Using a USB-mini connector for power.
  • It provides a Sensor List overview page to show all the sensors it is tracking and their last value.
WiFi Gateway Case

Tech Specs

  • Dimensions 74mm x 55mm x 28mm
  • Powered either by USB Mini cable and USB power supply, or battery connection (2.5V to 3.5V) via the 2 pin battery connection plug
  • Upgrades are done over the air using the Update button or can be done manually done using a 3.3V FTDI cable


  • Easy to configure web interface. No programming or soldering skills required. You do not need the internet to configure the device. Connect to it directly from any WIFI device (e.g. PC, phone tablet…)
  • Supports both Celsius or Fahrenheit temperature conversion Powered either by USB Mini cable (4.5V DC to 7V DC input) or battery connection (2.5V to 3.5V) via the 2 pin battery connection plug
  • The device supports dual WIFI mode allowing it to be WIFI access point and a WIFI client at the same time. A WIFI access point advertises itself through an SSID and can be connected to via any device or computer that has WIFI.
  • The Sensor List tab will show sensor that the WiFi Relay and heard and forwarded to the server. See Example below:

Required, but not included:

  • Mini USB cable and power supply (older cell phones used mini USB, so you may already have one in the bottom of a drawer).
  • Any USB power supply will work, 5 volts, 1 Amp or greater.

Setup Details

The configuration page for the WiFi Gateway is very similar to the WiFi IoT Sensor. You can configure the Wireless Gateway using any device that supports WiFi and an internet browser. In this example we will use a desktop computer. Click here for the Details Setup Guide

MQTT Details

  • Easy to configure web interface.
  • Connects to MQTT Broker with or without a username or password.
  • Tested with Mosquito Docker brokers and Emqx public broker.
  • JemRF provides an MQTT Broker for customers.

Mounting Instructions

Mount the Gateway in a vertical position with the USB connector down. There is a mounting hold on the back for this. Do not mount against a metal wall as that can block the WiFi and RF signals.
