Retained messages are lost on power off

When I re-boot the pi all retained messages are lost.
How to retained messages from power cycle.

You should setup the persistance,
check the example
The supported persistance type are defined in persistence.js.
Ponte uses Mosca for MQTT and persistance, so please check the persistance support wiki page to find out what additional options should be set for a particular storage type.

Sorry I'm not a expert all I want is to retained message after rebooting pls. Help

And I can't understand the example.
Where do I put this code.?
Pls advise.

please check the readme. You don't need to be an expert to read and follow the docs ;) You can either use the command line parameters to set each parameter separately or create a JSON file as in the example and start Ponte with:

$ ./bin/ponte -c /path/to/config.json

Cheers,
Jovan
