====Die JSON Daten eines SMA Batterie Wechselrichters über Telegraf in die InfluxDB schreiben=====

Im Prinzip gleich wie bei [[prod:telegraf_influx_shelly_plug|Die Daten eines Shelly Plugs über Telegraf in die InfluxDB schreiben]].


Der Trick ist der Parameter "insecure_skip_verify = true" in der <nowiki>"[[inputs.http]]"</nowiki> Section um den Zertifkatfehler zu händelen.


Für das Parsen des JSON Datensatzes ist das Tool https://gjson.dev/ hilfreich


----
=== JSON aufrufen und Werte finden ====

Über die URL **<nowiki>https://<SonnyBoyIP>/dyn/getDashValues.json</nowiki>** lassen sich die Daten des Batterie Storages auslesen.

Ausgewertet werden soll der Ladezustand % und der aktuelle Ladung, der passenden Schlüssel über die Werte in der Startseite des Batterie Storages.

==== Konfiguration ====

Abgelegt unter /etc/telegraf/telegarf.d/sma_batterie.conf

<code bash>

# Configuration for sending metrics to InfluxDB
[agent]
        round_interval=true
        interval="30s"



[[outputs.influxdb]]

  urls = ["http://192.168.1.212:8086"]
  database = "SOLAR"


# Send telegraf metrics also to file

[[outputs.file]]
  ## Files to write to, "stdout" is a specially handled file.
  files = ["stdout", "/srv/telegraf/metrics_SMA_BAT_SOLAR.out"]

  ## Use batch serialization format instead of line based delimiting.  The
  ## batch format allows for the production of non line based output formats and
  ## may more efficiently encode metric groups.
  # use_batch_format = false

  ## The file will be rotated after the time interval specified.  When set
  ## to 0 no time based rotation is performed.
  rotation_interval = "1d"

  ## The logfile will be rotated when it becomes larger than the specified
  ## size.  When set to 0 no size based rotation is performed.
  #rotation_max_size = "10MB"

  ## Maximum number of rotated archives to keep, any older logs are deleted.
  ## If set to -1, no archives are removed.
  rotation_max_archives = -1

  ## Data format to output.
  data_format = "influx"

# # Read SMA Batterie Storage
