Temporizador de cozinha (nodered, esphome, nodemcu+lcd)

Boa tarde, deixo aqui a minha idea para um temporizador de cozinha ou do que for preciso, está a funcionar bem mas provavelmente haverá alguém capaz de fazer o mesmo de forma mais simples, contudo deixo aqui a minha contribuição:

primeiro criar um inputbollean:

input_boolean:
  alarm_clock_status:
    initial: on

criar input_number:

input_number:
    alarm_clock_minute:
        name: Minutos
        icon: mdi:timer
        initial: 0
        min: 0
        max: 120
        step: 5

criar 2 scripts para aumentar de 5 em 5 min:

'1583966373784':
  alias: +5 minutos
  sequence:
  - entity_id: input_number.alarm_clock_minute
    service: input_number.increment
'1583966408415':
  alias: -5 minutos
  sequence:
  - entity_id: input_number.alarm_clock_minute
    service: input_number.decrement

no node-red instalar o node mytimeout atraves de: npm i node-red-contrib-mytimeout

com isto feito atravez do node red as seguntes automaçoes:

vou deixar apenas alguns nodes pois os que estão em falta são identicos aos que aqui deixo:











Breve explicação:
ao chegar ao fim o temporizador vai me fazer piscar os leds da cozinha e os leds do movel da tv, assim como o meu google home mini vai dizer"O temporizador chegou ao fim", assim como voltar a colocar o estado do temporizador em Desligado.

Feito isto resta apenas fazer Deploy e deverá funcionar conforme funciona comigo .

Acrescento também todo o projeto de hardware que utilizei para ter um temporizador fisico na cozinha para ajudar nos cozinhados :stuck_out_tongue:

Desculpem pelo post tão longo e provavelmente confuso, pois confesso que não tenho muito jeito para toturiais , mas tentei o meu melhor :stuck_out_tongue:
Alguma duvida estou ao dispor.
Obrigado a todos os que contribuem para esta comunidade pois é onde tenho aprendido quase tudo o que tenho implementado e obrigado a todos os que me ajudaram atraves do discord :mechanical_arm:

Bom continuação e bons projetos.
um Abraço
Luís

Boas.

Parabéns pelo trabalho . Interessante sobre tudo pela mistura de plataformas, que demonstra o poder do home assistant.

Concerteza que hei-de vir aqui algumas vezes tirar ideias, sobre tudo por causa do node-red. Também tenho um display oled desses em que já fiz umas brincadeiras também no esphome e é tão impressionante o tamanho dele (super-pequeno) como a definição ( alta definição.)

Bom projeto!

Falta colocares o código do node-red. O código é mais importante que os prints.

Obrigado :wink: já acrescentei

Bom trabalho, continua a partilha :wink:
