Has it arrived?

Yes, but unfortunately I have no time to play with it...

Hi, not working yet. I am waiting for arrive a RS485 module for Arduino, that I can test without z-uno.

Thanks, not a good news, it will be long...

Hi, I uploaded an official sketch to a Z-uno Shiled, with 4 sensors on ADC0-3: // Global variables byte pin3SensorBinaryState; byte pin4SensorBinaryState; byte pin5SensorBinaryState; byte pin6SensorBinaryState; // Z-Wave channels ZUNO_SETUP_CHANNELS( ZUNO_SENSOR_BINARY(ZUNO_SENSOR_BINARY_TYPE_GENERA...

The bug is in the modbus communication, Serial1.available() > 0 is false when it wants to write or read.

Hmm, If i put: return (55.33); in the controller says 0.55 V
or if x = x*100;
return (x);
result is -1.00V
Interesting.

Thanks, but should be an other bug too, it is reporting now -1.00V.

Hi all, I need to read data from an energy meter via modbus with Z-Uno shield. I can't find any useful examples for a sketch, I tried made a one, but it isn' working, maybe no answer from meter. Wired to shield's 7-8 pin, jumpers set to RS485. My sketch is below (reads voltage only), is anyone a goo...
