Error: , Remote I/O error

[Lennyz1988]

Hi,

When I try to use the input node, I am getting this error:

"Error: , Remote I/O error"

It only appears when I enter a correct command for the sensor.

For example:

254 == 0xFE

Should give me the temperature but I get the error. When I enter 253 or any numbers that isn't a command I get [ 0, 0 ] as a payload.

The sensor is hooked up 100% correct because with Domoticz I can get perfect readings.

Were you able to resolve this issue? I have a similar problem

I did never solve it using this module. I made a workaround by executing a python script using the exec node.

I am using this python driver for the HTU21DF.

Can anyone on this thread provide more information how to use this node and how the Command field is programmed?

Same problem. Developer ??

The command value is the first byte that is send to the device.

Is there a list of i2c commands for reference that can assist in understanding how to employ this generic i2c node for any i2c devices?? This is all greek to me (for now...). thx all
