@Nuno_Figueiredo podes postar uma foto do conversor que tas a usar? quais foram as ligações? foram as mesmas que postei acima no topico?
as ligações são as mesmas, apenas como é um MAX485 temos de ativar o DERE pin
fiz assim
sdm<2400, 12, 13, 4) - D6/D7/D4
no max485 uni o DE com o RE e levei essa ligação ao D4 do nodemcu. e estou a alimentar com 3,3v o max485 mas tb podia ser com 5v
onde consigo saber uma lista dos PIN com o que fica no arduino ide, por exemplo, ando as aranhas pq nunca sei que o pino do Tx ou Rx ou outro = no arduino a ??
como ja sei que por exemplo, 12 = D6, 13 = D7, 2 = D4.
o conversor é exatamente este.
1 Curtiu
@Nuno_Figueiredo faz me um favor… pega uma folha A4 e faz um desenho das ligações para esse conversor, há muita gente que não sabe ligar isso e tu conseguiste. podes fazer isso e colocar aqui por favor?
WObrigada Nuno vou testar isso a noite.
Quando escreveste 2400 falas do baudrate entre o SDM e o weemos correcto?
O meu SDM é um 220 e tem vários parâmetros da comunicação que são configuráveis:
Baudrate, parity, stop bit e ModBus adress.
Fica cá a foto das possíveis configurações do meu SDM!
FB_IMG_1527262888650|286x480
Também andei as cabeçadas durante muito tempo e nao consegui meter a funcionar se poderes partilhas tuas coisas com screen o HA a funcionar agradecia
nao alterei nada do sdm, esta como vinha.
uma coisa que ainda nao percebi como resolver e o nodemcu ficar sem wireless, já testei um delay de 30 segundos entre leituras, ou pode ser problema da minha rede, de qualquer das formas se alguem tiver o mesmo problema e tenha de ideia de como resolver avise, talvez seja possivel no codigo do arduino pedir para o wifi reconectar, basta desligar o nodemcu e voltar a ligar e fica a funcionar.

SDM<2400, 12, 13, 4> sdm
Eu uso o weemos, então o gpio4 corresponde ao D…?
desculpa frederico, eu ainda ando a tentar perceber os gpios no arduino ide, o D2 corresponde ao pin 4 no arduino ide, e chego aqui e termino, nao sei mais 
obrigado, ja esclarece 
será que o problema de perder o wifi esta na libraria? estou a usar o arduino ide que estava neste post.
o mesmo nodemcu com tasmota nao perde ligação.
mas o meu código do HA faz isso. E publica os valores por MQTT com retain para se reiniciares a placa ele vai ler o valor ao arrancar.
Falas do retain last state? Como o fizeste?
bem tentei compilar com as mais recentes librarias do esp e o nodemcu funciona bem, mas passado 2 comunicações perde a ligação ao MQTT, estou a tentar resolver o problema da perda de wireless ao usar as novas librarias, sem sucesso :S
os craques do arduino ide que ajudem
Eu com a adicão do 3o fio consegui comunicação e estou neste momento a editar para ter tensao, frequencia e afins em tempo real. Um muito obrigado ao @Nuno_Figueiredo pela grande ajuda.
Eu estou a usar um conversor desses e um weemos d1 mini para os que queiram saber se funcionam
partilha cmg depois se perdes ligação com o tempo e aleatoriamente, é o meu dilema de momento :\
O meu tá a comunicar mas como volta e meia ainda ando a fazer reboots e afins não posso propriamente ver se está a cair ou não.
Estás a usar o nodemcu ou weemos?
