The WiFi Wireless Gateway (WiFi Gateway) receives messages from the Wireless sensors and sends them to the PrivateEyePi or JemRF Monitoring server. 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 provides the Celsius to Fahrenheit conversion.
- 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.
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
Setup Details
The configuration page for the WiFi Gateway is very similar to the WiFi IoT Sensor. It also has the option for Celsius to Fahrenheit conversion. 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.
To make setup easy, the WiFi RF Wireless Sensor Relay has its own internal Web Server.
Step 1 Connect to WiFi
The first step is to connect your smart device to the WIFI sensor. Power up the WIFI sensor and using your computer (or smart device) look for a WIFI connection that starts with JRF followed by some numbers. These numbers are the unique ID of your sensor. Connect to the sensor using the default password:
Password: WiFirelay
Step 2 : Configure SSID and Password
Now open up a browser and navigate to http://192.168.4.1/.
Next enter the SSID and Password of your WIFI router and click on save.
Wait a few seconds for the WIFI temperature sensor to connect to the WIFI router. Click on the “Login Details” menu option to refresh the screen. Once connected you will see the WLAN: IP address has given to the Wireless Gateway, as shown in the next image. In the example below it shows 192.68.254.69, yours will be different. What’s important is your gateway is now connected to the internet.
Step 3 : Connect to Monitoring Server
The next step is to connect your sensor to one of our servers so you can monitor the sensor or create alerts. Both are have free online services. “www.PrivateEyePi.com” is our original server and it provides custom event triggering and well as basic monitoring. “monitor.jemrf.com” is our newer server focused on monitoring with custom tolerance settings to trigger notifications to help alert when there is a problem. You might want to visit each to see which meets your needs.
www.PrivateEyePi.com
If you have not registered an account with PrivateEyePi, go to https://www.privateeyepi.com and click on “Create User”.
Now enter your PrivateEyePi token. You can obtain your token from the User menu on www.privateeyepi.com website. .
The Gateway Server setting is: “www.PrivateEyePi.com” Copy and paste the token into the token field as shown in the below diagram
Monitor.JemRF.com
You can also use https://monitor.jemrf.com to create and account and token. To create an account you select the Register option on top right. Once registered you will receive a validation email with link. Click on the link and your account will be activated and ready for you to login. When you login under your name will be a drop down, select Account and then click on the Edit Token button. If you have a PrivateEyePi token already you can paste it in the token field and click the Accept Token to validate it is unique and Save. Now the same token works for both servers. If you do not have a PrivateEyePi Token, click Generate Gateway Id and it will create a token for you. Click the Accept Token to validate it is unique and Save.
The Gateway Server setting is: “pep.jemrf.com” Copy and paste the token into the token field as shown in the below diagram
Click “Save” and after a few seconds for the WIFI sensor to connect, clicking on the “Login Details” menu option to refresh the screen. Once connected you will see “PEP: Connected” as shown by the red circle in the image above. Once Connected, the Wireless Gateway is now forwarding Wireless Sensor data to the selected server.
Sensors List
The Sensor List page shows the sensors the gateway has forwarded messages to the PEP server. It also shows the last message from each sensor received by the gateway with how many messages have been forwarded for that sensor and a grand total of all the messages forwarded to the server.
It tracks messages for up to 64 Sensors.
