ansluta-control

Ikea Ansluta remote control by nodeMCU and CC2500 2.4Ghz transceiver via arduino

This project was created to control Ikea Omlopp/Utrusta lights by webbrowser or add it to a home automation system (FHEM) The original remote has one Button. With every push the lights cycle -> 50% -> 100% -> 50% -> off

The remote send a series of data icluded two own address bytes.

• example: 0x55 0x01 0xD0 0x9A 0x02 0xAA (0xD0 & 0x9A my addressbytes)

Hardware:

• Lolin NodeMCU V3 az-delivery
• CC2500 Transiver module (WLC24D) ebay

Software:

• Arduino IDE www.arduino.cc

Setup Arduino IDE

• Go to Tools -> Boards Manager and seach 'nodemcu'

• install -> 'esp8266 by ESP8266 Community'

• Select Board: NodeMCU 1.0 (ESP.12E Module)

• Set CPU Frequency to 160 Mhz

• Select com port

Get the Ansluta address bytes from your remote

• start Arduion ide, load project files
• edit ansluta.ino -> set your SSID and Wlankey at row 40, 41
• write project to nodeMCU
• determine your nodeMCU IP and connect browser. example: 192.168.178.130/ansluta/getAddress
• press button on original remote
• note your AddressBytes
• edit ansluta.ino -> set your AddressByteA and AddressByteB at row 54, 55
• write project to nodeMCU

Control the lights via webbrowser

connect to nodeMCU IP press button: off, 50% or 100% to toggle the lights

Control the lights via FHEM
