Tasmota returns values and names based on the definitions you put in the script.
The standard command http://192.168.xxx.xxx/cm?cmnd=status%208 (where 192.168.xxx.xxx is the IP Adress of your Tasmota) will return the values that are available, for example:
{ "StatusSNS": { "Time": "2023-12-10T20:17:41", "Wohnung": { "server_id": "0a01415041010557ff7d", "total_kwh": 819.9, "export_total_kwh": 251.48, "aktuelle_Wirkleistung": 557, "freq": 50, "amp_p1": 0.98, "amp_p2": 0.45, "amp_p3": 1.46, "curr_w_p1": 184, "curr_w_p2": 82, "curr_w_p3": 289, "volt_p1": 240.8, "volt_p2": 240.9, "volt_p3": 241.3, "phase_angle_l2_l1": 238, "phase_angle_l3_l1": 118, "phase_angle_p1": 330, "phase_angle_p2": 325, "phase_angle_p3": 333 } } }
In this case, the value aktuelle_Wirkleistung is the one we need.
In order to extract the correct value, you need to notice the number of curly brackets { and the titles
Based on the example above: {"StatusSNS": {"Wohnung": {"aktuelle_Wirkleistung": 557
Subsequently the JSON Pfad you need to enter is:
StatusSNS/Wohnung/aktuelle_Wirkleistung
