Reading and displaying analog values from other node

[Artur]

Hi.

Howto read analog values (temperature, humidity...) from other node (in my case gateway). 

PullData, read data are changing when temperature are changing buy I don't know how to easily convert read values back to float type.

RemoteInputs, always returns zero.

I'm using WeMos D1 mini with Oled shield as node and Ethernet gateway with sensors.

Hi Artur,

mOutputAsFloat(slot) should work for you.

Regards,
Dario.

If you have it working can you please post your sketches? (peer and gw)

I get the correct temp & humidity on my peer

but I really don't know how to serial.print it on my gateway (connection over rs485)

You should use Persistance or LastIn (suggested), details on the wiki.

Ok I got it working with LastIn:

#include "conf/Gateway_wLastin.h"

Serial.print(LastIn_GetAnalog(1,5));          //Temp
Serial.print(LastIn_GetAnalog(1,7));          //Humid

but with Persistence I only get 0.00 values

#include "conf/Gateway_wPersistence.h"
Serial.print(pOutputAsFloat(1,5));          //Temp
Serial.print(pOutputAsFloat(1,7));          //Humid

on a Mega2560

what is wrong?

[Di Maio, Dario]

Looks strange, you are not supposed to do anything else to work with Persistence. I assume that those values are available in SoulissApp without any problem when Persistence is set.
