# Pushbutton to switch Space-API-Status
|
||||
Hardware-Schalter, um den Space-API-Status umzuschalten. Nach dem Umschalten wird 30 Sekunden lang der Status aus der Space-API angezeigt. Danach wird der ESP in den Deep Sleep versetzt. Somit kann der ESP auch mit einer Batterie/Akku verwendet werden.
|
||||
|
||||
## Funktionsweise
|
||||
1. Der Space-API wird per POST request ein JSON übermittelt `{"open":"false","trigger_person":"Space-Button","message":""}`. Dabei wird ein Bearer Token für die Authentisierung verwendet.
|
||||
2. Der Space-API Status wird abgerufen. Da es Probleme mit der Auswertung des JSON-Strings gab, wird im Beispiel nur 1 oder NULL zurückgegeben und ausgewertet.
|
||||
|
||||
## Einsparungsmöglichkeiten
|
||||
Um nach dem Wakeup schneller den Status anzeigen zu können, sind folgende Optimierungen möglich:
|
||||
|
||||
- kein DHCP
|
||||
- kein DNS resolve
|
||||
- kein MQTT
|
||||
|
||||
bereits umgesetzt:
|
||||
- WiFi-Fastconnect
|
||||
- HTTP deaktiviert
|
||||
- mdns deaktiviert
|
||||
- kein Logging
|
||||
|
||||
## Anzeige
|
||||
Rot: Space geschlossen
|
||||
Grün: Space offen
|
||||
Blau: Batterie leer
