"info": "This node translates between Loxone home automation and IKEA Tradfri gateway. \n\nIt is to be used for tunable white light bulbs and converts brightness and color temperature between both worlds. \n\n**NOTE:** It is based on the the **node-red-contrib-ikea-tradfri**__ nodes and only works with the IKEA tradfri gateway, NOT with other zigbee gateways, e.g. does not with a Philips Hue bridge or conBee USB sticks! \n\nIt also requires the **node-red-contrib-loxone**__ nodes!\n\nMany thanks to the authors of these excellent nodes - Michael de Wit and Patrik Mayer!\n\nIt allows changes from BOTH sides, e.g. IKEA remote controls, IKEA smart home app, Loxone app and other Loxone logic at the (almost) same time. \n\n\nEnjoy!\n\nSome technical information:\n\nunits for brightness:\n - Loxone is using integer numbers from 0=dark to 100=bright\n - IKEA is using integer numbers from 0=dark to 254=bright\n - node-red-contrib-ikea-tradfri is using decimal numbers with one decimal place from 0.0=dark to 100.0=bright\n\nunits for color temperature:\n - Loxone is using integer numbers in Kelvin from 2700=warm to 6500=cold\n - IKEA is using integer numbers in Mireds from 250=cold to 454=warm\n - node-red-contrib-ikea-tradfri is using decimal numbers with one decimal place from 0.0=cold to 100.0=warm\n\nThe communication is fully event based and does not poll each side. There are little problems with the conversion of units that are solved by using a short \"lock\" of a few seconds once one side - either Loxone or IKEA Tradfri gateway - has send a new event. By using this lock an ongoing \"ping pong\" is prevented.\n\nOn the Loxone side you may use the light control v2 function block with an output of type lumitech that is connected to a virtual output (no real address required) and a virtual output command (again, no specific configuration required). The output just has to be defined to be included in the structure file (http://miniserver/data/LoxAPP3.json).\n\nOn the IKEA tradfri side you have to deal with the instance ID's of your light bulbs, but with a debug node that is connected to the tradfri-monitor node it is quite easy to see all information from your light bulbs that have changed their values.",
