Ajuda na passagem de payload entre nodes diferentes

Tenho o meu sistema de alarme com triggers através de reconhecimento humano praticamente terminado excepto um pequeno detalhe relacionado com a payload que preciso passar por dois nós diferentes.

Aqui está um screenshot do meu flow (adicionada a seta vermelha apenas para deixar claro para onde a payload do Convert deve ser enviada e onde adicionei as condições do estado de alarme):

Aqui está o código de parte da flow :

Como posso passar as várias payloads do node Converter ao mesmo tempo que adiciono as condiçoes do alarmstate no meio sem perder a informaçao?

Obrigado !

Podes por exemplo colocar o payload dentro de uma variável. VÊ se isto ajuda:

http://www.steves-internet-guide.com/node-red-variables/

Em especial o capitulo “Exchange Data Between Nodes Without Wires”

@j_assuncao obrigado mas creio que neste caso a soluçao era bastante simples, bastava mudar os nomes dos payloads de cada node para conseguir reter ambos :slight_smile:
