Request Value from Node
-
I am using the pulse power meter but I didn't use any dummy variable. Also the controller plays a role too.

@gohan you don't use a dummy variable (VAR_1)? So who do you know when the message arrives if it's a request?
I think that @Soloam is asking how can a gateway request a value from the node not how node can request a value from gateway. If so then You must hadle it in the receive funtion (https://www.mysensors.org/download/sensor_api_20#requesting-data). The request message has distinct command type (https://www.mysensors.org/download/serial_api_20). You can get the message command type with getCommand method - unfortunetly this is not documented ... why ?

@rozpruwacz You are rigth, I Want GW => Node Request or Node => Node Requests, and I've seen the command type in the notes, but who can I access that command value in the code?
1;1;2;0;2;0 - Requesting Node 1 Child 1 variable V_STATUS, Who do I know that the Command is 2 (request) ?

@soloam looks like you should be able to use mGetCommand and check for C_SET / C_REQ.

@mfalkvidd thank you, that will do the job! I leave the ideia to a isReq()! :)
Thank you all

1;1;2;0;2;0 - Requesting Node 1 Child 1 variable V_STATUS, Who do I know that the Command is 2 (request) ?as I said You need to use getCommand method on the message object.

Is this mGetCommand is official API ? because it does not look like. I wouldn't use undocumented methods, because they may disapear in new releases.
