Manually inspecting the EventSource

You can inspect the EventSource using your browser, e.g. Chrome.

1. Open the Network inspector by right-clicking the index web page:
   

   

2. Chose the Network tab (the 3rd or 4th):
   

   

3. Select the latest events file (Name column)

4. Right-click a recent state event and Copy message:
   

   

Now you have the JSON representation of the event on your clipboard, e.g.:

{"m":"HAN","W":533,"Wh":10873784,"t":"2024-02-13T08:01:50+0100","Ph":0,"Rh":3262987,"Qh":2061467,"P":0,"R":0,"Q":394,"L1":254,"P1":0,"R1":0,"Q1":221,"I1":1.400,"U1":229.000,"L2":237,"P2":0,"R2":0,"Q2":130,"I2":1.100,"U2":229.800,"L3":40,"P3":0,"R3":0,"Q3":42,"I3":0.200,"U3":232.300,"sec":1707807710}

The EventSource messages and MQTT messages share the same format and contents.
