SmartLEDLamp

A smart, web-enabled floor lamp with nice visual effects based on IKEA Vidja powered by ESP8266. IR or http controlled.

Looks like this (some examples):

Making of

Ingredients

• IKEA Vidja
• ESP8266 (Wemos D1 or a similar variant with 4MB flash memory)
• 5m WS2801 (160 LEDs)
• Power Supply 5V, 10A
• Cable straps, resistors, capacitors, duct tape, few hours spare time...
• (optional) IR Sensor (e.g. VS1838) plus Mini led controller 44 (search aliexpress)

How to Build

• Make sure to use a memory layout with 3M SPIFFS

• The following libraries are needed:

  • From Arduino core for ESP8266:
  • ArduinoOTA
  • DNSServer
  • EEPROM
  • ESP8266mDNS
  • ESP8266WebServer
  • ESP8266WiFi
  • Hash
  • 3rd party:
  • ArduinoJson - https://github.com/bblanchon/ArduinoJson
  • FastLED - https://github.com/FastLED/FastLED
  • WebSockets - https://github.com/Links2004/arduinoWebSockets
  • WiFiManager - https://github.com/tzapu/WiFiManager
  • ArtnetWifi (optional, check for ARTNET_ENABLE in defines.h to activate) - https://github.com/rstephan/ArtnetWifi (to use http://www.solderlab.de/index.php/software/glediator for example)
  • IRremoteESP8266 (optional, only if you want to use an IR receiver; If so, check for IR_ENABLE in defines.h to activate) - https://github.com/markszabo/IRremoteESP8266
  • PubSubClient (optional, check for MQTT_ENABLE in defines.h to activate) - https://github.com/knolleary/pubsubclient

• Compile & upload

First Start

• After initial upload ESP8266 is running in AP mode offering a WiFi AP connection called SmartLEDLampAP.
• Connect to that WiFi and open http://192.168.4.1 in your browser if it isn't shown automatically.
• Configure WiFi by supplying WiFi name plus password, save, wait a minute and restart the ESP8266.
• If connect data was right, ESP8266 is now accessible from your local network. IP is shown in the console as logging output:

  Info: Starting Smart LED Lamp 0.2
  Info: Free Sketch Space: 622592
  Info: No config file found, using defaults
  Info: IP: 192.168.0.110
  Info: HTTP server started
  Info: WebSocket server started

• Now build and upload SPIFFS. In folder SmartLEDLamp run

  mkspiffs -p 256 -b 8192 -s 3125248 -c data spiffs-image.bin

  and

  espota.py -i <IP> -s -f spiffs-image.bin

  Don't worry if the latter comes back with an error after upload.

• Alternatively you can use ArduinoIDE Plugin for SPIFFS upload.
• Restart ESP8266

Usage

• More often than not LED stripes won't be plain white when R, G and B are fully powered, thus you may want to calibrate your stripes. Go to http://<IP>/config.html to apply and save your calibration (Tip: this is done most easily turning on the lamp with fully brightness and white color.)
• You can access a web remote control page at http://<IP>/control.html to access a web control page showing the remote (please also refer to data/rc.jpg)
  • Most buttons are self-explaining. Here's just the special stuff:
  • 3rd button in the first row allows to start and stop animations
  • JUMP3 - Rainbow animation - Try QUICK/SLOW and the blue up/down arrows
  • JUMP7 - Fire animation - Try QUICK/SLOW, different up/down arrows (fire parameters), DIY1-6/AUTO (choose color palette)
  • FLUSH - FastLED noise animation - Try QUICK/SLOW, blue up/down arrows (scale), red up/down arrows (choose color palette)
  • FADE3 - FastLED DemoReel animations - Try red up/down arrows
  • FADE7 - VU Meter - commented out in the code. You can run a microphone or line in on A0 of the ESP8266 to drive the VU Meter. You'll have to poke around with the code to make this work. Look for readAnalogPeek and the code calling it in loop in LEDLamp.cpp.
• Remote logging is available via port 8888. You could use PuTTY to connect to your lamp's IP, port 8888 using connection type raw and you will receive logging output like key presses and so on.

Home Automation Integration

The following web API is available to integrate the SmartLEDLamp into OpenHAB for example:

http://<IP>/action/?act=on - Turn the lamp on
http://<IP>/action/?act=off - Turn the lamp off

http://<IP>/action/?btn=1 - Simulate press button 1
http://<IP>/action/?btn=17 - Simulate press button 17

http://<IP>/action/?brightness=17 - set brightness to 17%
http://<IP>/action/?brightness=100 - set brightness to 100%

Additionally you can use MQTT (see above on how to enable, configure MQTT_SERVER and MQTT_TOPIC in defines.h appropriately). Message of "0" sent to the topic turns the lamp off, a message of "1" turns it on. Furthermore same topic is reflecting the state if lamp is turned on or off via web interface or IR.
