I'm beginner in "Node-red", can you tell me what I'm doing wrong? I have output like this 01.09.2020, 17:13:21node: 1acab143.6805af zigbee2mqtt/0xec1bbdfffe6dff16 : msg.payload : Object object update_available: true state: "OFF" linkquality: 76 brightness: 254 color_temp: 254 color: object x: 0.45…

If my assumption was correct then your original if statements were incorrect. Here is the flow with a corrected version and a second flow showinng how you could do it without a function node. [{"id":"15069f84.a068c8","type":"function","z":"94b68392.acdaf8","name":"","func":"// initilize flag to he …

Whilst waiting for detailed help I suggest you work through the node red essentials videos, that will give a lot of useful information and may well allow you to answer the question yourself.

Where you use this msg1.payload = msg.payload.state; try using msg1.payload.state = msg.payload.state;

[image] zenofmud: msg1.payload.state = msg.payload.state; it writes: "TypeError: Cannot set property 'state' of undefined" I found a solution, not as pretty as I want, but it works! [answer] Now, I want to write the code so that I would receive a message only when the status has changed,…

[image] Zerg: But, my condition is not met! it write to me state all time, don't understand where I did mistake?!?! Try this, change these lines: var flag = flow.get('flag') || ""; node.log(typeof p); msg.payload=p.state; to var p = {} p.status=msg.payload.status; msg.payload = p; Msg.…

I redid it according to your instructions. p=msg.payload; var p = {}; var flag = flow.get('flag') || ""; p.status=msg.payload.status; msg.payload=p; if(p.status == "ON" && flag != "ON") { msg.payload = {"state":"ON"}; flow.set('flag',"ON"); } else(p.status == "OFF" && flag != "OFF")…

My mistake, I should have said get rid of the four lines p=msg.payload; var flag = flow.get('flag') || ""; node.log(typeof p); msg.payload=p.state; You also don't need the msg.payload = {"state":"ON"}; and msg.payload = {"state":"OFF"}; ' since you have already set msg.payload=p;` which is the…

Does not work! Or I misunderstand you? p=msg.payload; var flag = flow.get('flag') || ""; node.log(typeof p); msg.payload=p.state; if(msg.payload == "ON" && flag != "ON") { msg.payload = {"state":"ON"}; flow.set('flag',"ON"); } else(msg.payload == "OFF" && flag != "OFF");{ msg.p…

[image] Zerg: else(msg.payload == "OFF" && flag != "OFF");{ msg.payload = {"state":"OFF"}; flow.set('flag',"OFF"); } as I said previously, in your IF statement you have a test in the else - you need to use else if so else(msg.payload == "OFF" && flag != "OFF");{ needs to be e…

Object programming it is my weak side! And I don't understand why the checking of flag doesn't work!? it should write in debug window only then the status has changed! And it writes to me all the time, which indicates that the condition if(msg.payload == "ON" && flag != "ON") { does not work! My …

[image] Zerg: Object programming it is my weak side! This isn't object programming. Import this small flow so you can see what I am talking about. I have commented the function node to explain what is happening. [{"id":"19a4f700.d59c91","type":"function","z":"94b68392.acdaf8","name":"","fun…
