Ras Pi supply voltage

General

Seems indeed the vcgencmd is Raspberry specifc, and other devices with Broadcom VideoCore processors. So I agree we should put this stuff in a separate node. Read somewhere that vcgencmd stands for "VideoCore general command". Should we call it node-red-contrib-videocom?

How should the output look like: an array of booleans in the payload? E.g.

{
    "payload": {
        "under_voltage_detected" : true,
        "arm_frequency_capped" : true,
        "currently_throttled" : true,
        "soft_temperature_limit_active" : true,
        "under_voltage_occurred" : true,
        "arm_frequency_capped_occurred" : true,
        "throttling_occurred" : true,
        "soft_temperature_limit_occurred" : true
    }
}

Or should it be separate messages with their own topic? E.g.

{
    "payload": true,
    "topic": "under_voltage_detected"
}

Indeed ...
