How to Use

Setup the Device

1. Supply power to the device.
2. Connect your cellphone or laptop to Wi-Fi SSID “IR-Station”.
3. Access http://192.168.4.1 in a browser
4. Enter Wi-Fi SSID of your home and its password
5. Enter a device name you like. We call it the hostname. Because it will be a part of URL, you cannot use space character.
6. If connection succeeded, IR-Station’s local IP address is displayed. Please make a note of it.
7. Connect your cellphone or laptop to your home’s Wi-Fi.
8. Access http:/xxx.xxx.xx.xx (IR-Station’s local IP address) in a browser. (for example http://192.168.11.3 )
9. If something appears, setup is complete.

Store Signals

1. Access http:/192.168.xx.xx (one example) in a browser. 1. Look at the form of the bottom of the screen.
2. Select “record a new Signal” action.
3. Select a channel you want to assign a new signal.
4. Enter a name of the signal.
5. When you click the “Submit” button, the green LED of your IR-Station will light up.
6. Press a button on your remote controller toward your IR-Station to store a new signal.

Remote Control

1. Access your IR-Station in a browser.
2. Click a button which assigned a signal you want to send.

How to Make

Required Library

Please Add the Libraries below to your Arduino IDE

• Arduino Json (https://github.com/bblanchon/ArduinoJson )
• Arduino Time Library (https://github.com/PaulStoffregen/Time )

Steps

1. Gather the components.
2. Assemble the components according to the circuit diagram.
3. Connect the device and the PC with a serial-to-USB conversion module.
4. Prepare Arduino IDE and serial-USB converter’s driver.
5. Open the preferences of Arduino IDE and fill in this URL: http://arduino.esp8266.com/stable/package_esp8266com_index.json to “Additional Boards Manager URLs”.
6. Add “Generic ESP8266 Module” in the Arduino IDE Board Manager.
7. Add the required libraries to your Arduino IDE in the Arduino IDE Library Manager or zip files.
8. Open IR-Station firmware in the Arduino IDE.
9. Select “Generic ESP8266 Module” and configure each item of board settings properly. See Arduino Board Settings below.
10. Select correct serial COM port and upload program to the device. When upload program, GPIO0 and GPIO2 must be pulled-up, and GPIO15 must be pulled-down. It’s necessary to reset the device immediately before upload. It’s a little difficult.
11. The uploading takes about 30 seconds.
12. Upload the SPIFFS data: menu -> tool -> ESP8266 Sketch Data Upload. (See https://github.com/esp8266/Arduino/blob/2.3.0/doc/filesystem.md )
13. Process termination.
