1- access token de home assistant.
En home assistant, botón configurar usuario (arriba la izquierda, inicial del usuario), Tokens de acceso de larga duración. Crear uno y copiarlo.
2- Token del boot de telegram. Se obtiene al crear el boot de telegram
3- Telegram id. yo lo obtuve preguntando al boot IoTwithus.com escribiendo /myid
Doble click en el nodo "cambio estado rele", boton editar server, poner la url (http://localhost:8123) y el access token (1)
poner también el mismo server en "cambio estado luz"
doble click en el nodo "telegrambot", y configurar el acceso al boot (boot-name, token (2), y chatid (3)
doble click en el nodo "componer mensaje" y poner en chatId :XXXXXXXXXX el de nuestro chat (3)
Si todo va bien, en cada cambio de estado de cualquier luz o rele, lo notifica. por ejemplo: "luz salon encendida" o "luz salon apagada".
