Introduction |
||||
|
============ |
||||
|
|
||||
|
Le but est d'avoir un selecteur d'effet + mode off. |
||||
|
Pour lancer l'effet sur le LED Strip@D1 (GPIO5) : |
||||
|
```bash |
||||
|
mosquitto_pub -d -u "<USER>" -P "<PASS>" -t "<TOPIC>" -m "ON" |
||||
|
``` |
||||
|
Pour l'arreter : |
||||
|
```bash |
||||
|
mosquitto_pub -d -u "<USER>" -P "<PASS>" -t "<TOPIC>" -m "OFF" |
||||
|
``` |
||||
|
|
||||
|
Un exemple de configuration pour home-assistant se trouve dans [ha_configuration.yml](ha\_configuration.yml). |
||||
|
|
||||
