Step 1: Download and install “weather” in the node management, as shown in the following figure:
Step 2: find “weather” in the sidebar and drag it into the process, as shown in the following figure:
Step 3: drag “function” into the process and write the following code, as shown in the following figure:
let code;
code = msg.payload.current.weather;
switch(code) {
case '0':
Status ='sunny '
break;
case '1':
Status ='cloudy '

return msg;Step 4: drag “debug” into the process to monitor the debugging window, as shown in the following figure:
Step 5: drag “link in” and “Linkout” into the process to link input and output, as shown in the following figure:
Step 6: according to the data to be displayed, drag “function” into the process to mark the corresponding functions. I have done a comprehensive job here, and the codes in sequence are as follows:

// ]
],
"labels": []
}];
var lTemp = [];
var hTemp = [];
var values = msg.payload.forecastDaily.temperature.value;
var date = new Date();
date.setHours(0);
date.setMinutes(0);
date.setSeconds(0);
date.setMilliseconds(0);
var x = date.getTime();
for(var i in values) {
lTemp.push({
"x": x,

Step 7: if you want to further explain some obtained data, you can refer to some information in the debugging window, as shown in the following figure:
Step 8: link the corresponding modules in the process, as shown in the following figure:
Step 9: enter the UI interface to see the effect. Some specific presentation methods can also be adjusted according to your actual needs. I have made the following figure for reference:
The above is only some implementation operations of many materials on the personal reference network.
