I will be glad to know what I missing.  
I have two integration in the thingsboard one is linked to The Thing Network and one to The Thing Industries. I have two class C electric plug capable to switch the output OFF/ON Same code everywhere. The plug linked with TTN is working . the plug linked with TTI is getting the upload data but not receiving the download. why???  
I have a gateway for each network and both do not show the downlink for the device on TTI.  
if I register the device to TTN everything is fine.  
thanks in advance  
is there a different format in the downlink code to be used? or different setting?

var data = { downlinks: [{ f\_port: 2, confirmed: false, decoded\_payload: { “output”: msg.params.replace(/"/g,"") }, priority: “NORMAL” }] };

var result = { contentType: “JSON”, data: JSON.stringify(data), metadata: { devId : metadata.deviceName //get devID from alias } }; return result;

( may be is an issue for thingboard?)

Is the TB instance running on the TB cloud (rather than standalone or AWS install?) If so I think the TB supplied Integration assumes the public TTN community servers, your reference to TTI implies a private instance to me.
