I use Node Red and MQTT around the house for a simple home automation system. After getting Tado installed, I wondered how easy it would be to link it in. Actually, it is very easy:<\/p>\n

This flow pulls info from the Tado site every minute and creates MQTT messages for my other flows to pick up. As I have other wireless temperature nodes around the house, I could spot that the heating is on and a window is open by looking at temperature differences around the house.<\/p>\n

For the HTTP Request node:<\/b><\/p>\n

And the Function Node<\/b><\/p>\n

These were the items I was interested in. There are others available, type the HTTP Request line into your web browser to see them all.<\/p>\n

if (msg.payload === \u201c\u201d ) {
\n<\/i> return null;
\n<\/i> }<\/i>
\n<\/i>var tado = JSON.parse(msg.payload);
\n<\/i>context.global.tadotemp = tado.insideTemp.toFixed(1);
\n<\/i>msg1 = {topic:\u201cHouse\/Tado\/insideTemp\u201d,payload:context.global.tadotemp};
\n<\/i>msg2 ={topic:\u201cHouse\/Tado\/operation\u201d,payload:context.global.tadooperation};
\n<\/i>msg3 = {topic:\u201cHouse\/Tado\/operationTrigger\u201d,payload:tado.operationTrigger};<\/i><\/p>\n

msg4 = {topic:\u201cHouse\/Tado\/setPointTemp\u201d,payload:tado.setPointTemp};
\n<\/i>context.global.tadocontrolphase = tado.controlPhase;
\n<\/i>msg5 = {topic:\u201cHouse\/Tado\/controlPhase\u201d,payload:context.global.tadocontrolphase};
\n<\/i>return [msg1, msg2, msg3, msg4, msg5];<\/i><\/p><\/blockquote>\n

The extra function node\u00a0\u201cAdd Tado Temp\u2026\u201d just takes the Tado Temperature and adds it to another Topic<\/p>\n

The Debug output is shown below:<\/p>\n

Hope that this is useful!<\/p>\n
