Operating time - cflurin/node-red-contrib-dsm GitHub Wiki

The operating time dsm calculates the time a device is on.

Usage

topic	action
on	starts or continues counting
off	stops counting
reset	sets the counter to 0

Settings

"data": {
   ....
   "interval": 1,
   "interval_output": true,
   "hms_format": true
}

• interval: time in seconds
• interval_output: true > a msg is sent after every interval
• interval_output: false > a msg is only sent at stop
• hms_format: true > time format hh:mm:ss
• hms_format: false > time in seconds
