Einführung

Der Tesla Powerwall 2 wird als Batterie in eine Solaranlage integriert. Hier dient er als Energiespeicher. Es gibt eine App "Tesla" um den aktuellen Status als Benutzer auszulesen. Dazu gibt es noch eine lokale Webseite, die ebenfalls Zugriff auf den Status gibt.

Zusätzlich hat die Tesla Powerwall auch ein Web Api um Informationen auszulesen. Das kann genutzt werden, um die Powerwall auch in FHEM zu nutzen. 

https://<ip-address powerwall>/api/system_status/soe
https://<ip-address powerwall>/api/meters/aggregates
https://<ip-address powerwall>/api/site_info
https://<ip-address powerwall>/api/sitemaster
https://<ip-address powerwall>/api/powerwalls
https://<ip-address powerwall>/api/networks
https://<ip-address powerwall>/api/system/networks
https://<ip-address powerwall>/api/operation
https://<ip-address powerwall>/api/status
https://<ip-address powerwall>/api/customer/registration

Es gibt aktuell mehrere Forumeinträge dazu:

Installation

Benötigt wird das FHEM Modul TeslaPowerwall2AC

Zur Installation definiere in FHEM die Powerwall: 

define myPowerWall TeslaPowerwall2AC 192.168.x.y
attr myPowerWall emailaddr <your mail address used with Tesla gateway>

Danach muss noch das Passwort vom tesla Gateway gesetzt werden: 

set myPowerwall setPassword pass=<your password>

Nach einem Shutdown/Restart sollte der Tesla Speicher im Status "ready" angezeigt werden.

Gplots
