# SpaceAPI notifier
|
|
|
|
Nodemcu v0.9/v3 + MAX7219 LED matrix display project.
|
|
|
|
Displays configurable message on the display when the (also configurable) [SpaceAPI](https://spaceapi.io) endpoint state is open.
|
|
|
|
Initial WiFi configuration is done by connecting to the SPACEAPI NOTIFIER access point and going through WifiManager captive portal.
|
|
|
|
Custom SpaceAPI endpoint to query, displayed message configuration is then done on http://spaceapi-notifier.local/.
|
|
|
|
All parameters (WiFi and customizations) can be reset by pressing GPIO0 (flash button on Nodemcu) continuously until the LED_BUILTIN blinks.
|
|
You then have to reconfigure the WiFi and custom settings.
