Data Storage and Retrieval with ThingSpeak for Electric Imp Connectivity

Electric Imp is a connectivity platform for connecting Wi-Fi devices to cloud services, much like and Iota Wi-Fi modules and Some Electric Imp module’s come in an SD card form factor and adds Wi-Fi connectivity to what’s connected to the Electric Imp module. Access to the Electric Module happens via the Electric Imp cloud and its APIs. While connectivity is simplified with the Electric Imp system, you will need a data service like ThingSpeak to complete the Internet of Things experience. Once data from Electric Imp devices are in ThingSpeak, you can easily build applications and interactivity with other devices and platforms.

Electric Imp to ThingSpeak Overview

Once an Electric Imp module is connected to a local Wi-Fi network, the module can post data to ThingSpeak via an “agent” running on the Electric Imp Cloud. Any data can be sent to ThingSpeak and then retrieved via ThingSpeak APIs.

Note: If the BlinkUp fails, try checking the “Legacy BlinkUp Mode” option.

Step 6: Program Electric Imp via the Planner IDE

In this tutorial, we are going to send the Analog Input value from Pin 9 of the Electric Imp to a ThingSpeak Channel. In order to program the Electric Imp, sign in and copy the Electric Imp sample code into the Electric Imp Web-based IDE.

  • Visit
  • Sign in with your existing Electric Imp Account
  • Select the registered Electric Imp device
  • Copy the “send_analog_input/agent.nut” example code into the Agent section
  • Change the “X-THINGSPEAKAPIKEY” from “XXXXXXXXXXXX” to your ThingSpeak Channel’s Write API Key
  • Copy the “send_analog_input/device.nut” example code into the Device section
  • Click “Build and Run”
