NodeRed: Precios PVPC. Calienta tu termo más barato.

NodeRed: Precios PVPC. Calienta tu termo más barato.

En el capítulo de hoy aprendemos como integrar los Precios Voluntario al Pequeño Consumidos (PVPC) de la energía eléctrica en NodeRed. Esto nos va a permitir gestionar nuestros consumos eléctricos y conseguir ahorros activando nuestros consumos en los momentos más baratos del día. Además aprendemos a utilizar más nodos de NodeRed como el nodo switch.

Aquí tenéis el código del flow del PVPC
