Hi,

I would edit my topic message.
Initial topic and pay load looks like this

Topic: 02000001000047F9/update/zb/dev/6/ldev/humidity/data/humidity Payload: {"key":"humidity","name":"Relative Humidity","type":"double","unit":"% RH","access":"r","lastUpdated":"2019-01-11T09:29:18.327+01:00","value":34.0}

I would like to include the device id into the message , in this case device id is 6.

After editing it should look like this

{ "id":6, "key":"humidity","name":"Relative Humidity","type":"double","unit":"% RH","access":"r","lastUpdated":"2019-01-11T09:29:18.327+01:00","value":34.0}

I am not sure how to achieve this with out writing an extra client . Can u it be done inside the broker ?
