Update Frequency Parm Not Being Read

[funetn]

First thank you for the plug-in. Just installed and happy to see my sensors in HomeKit now. However I noticed when I changed the "update_frequency": 30 value to something else (I can live with 5+ min updates so changed to 300 and rebooted) that the plug-in still is polling ever 30 seconds per the log ("wait | 30 seconds").

I'm not a coder but I see in the code (platform.js) the following line of code:
this.updateFrequency = this.config.update_frequency || 30;

Is the JSON value (update_frequency) not getting correctly read by the program?

Updated (added JSON & log capture):

JSON:
"exclude_equipment_sensors": false,
"update_frequency": 600,
"log_level": 1
