Good night friends!

I'm trying to plot measurements from the psychometric chart (absolute humidity, specific humidity, enthalpy, etc.)

Values come in a json format with "value" and "ts"  
`003861/update/sensor/WB {"dev": "003861", "reg": "WB", "value":22.2, "unit":"┬░C", "ts":1676218679, "sh" :"669070"}`

I want to plot the data in a live graph like this:

> **[Line Chart Adding Data Every Second - amCharts](https://www.amcharts.com/demos/line-chart-adding-data-every-second/)**

can someone help me with formatting the data?
