Hi,
I'm newbie in node red.
For me it's an excellent tool with a high potential.
In a RPI3B+ I have made a sqlite DB write, dashboard and openweathermap get, and it's working ok, but I need to solve two problems that I don't know how to do it.
1- In the modbus Serial I need to sequence the polling. I've made a function to do this, but I think that work in boolean outputs it's not right.
Code function I've made:
var now= new Date();
var seg= now.getUTCSeconds();
var msg1,msg2,msg3,msg4;
if (0>seg<10) {msg1=true;}
else{msg1=false;}
if (10>seg<20) {msg2=true;}
else{msg2=false;}
return [msg1,msg2];
In debug window message me: "Function tried to send a message of type boolean"
How can I do this sequence work fine?
The variables I read in modbus, I want to save in a global to use this values in other flows. How can I do it?
Thanks in advance
