PB Updates

[brianhealey]

This draft PR contains updates to the protocol buffer schema exposed by the tesla powerwall+ (and hopefully others) api's.

These changes are breaking protocol buffer changes, and will require some code to that uses it to be updated.

Thank you @brianhealey !

• [ ] It appears that connectionParameters is not correct. The only instance that is populated in my vitals output is for the NEURIO where field called ipAddress has the value PWRview-XXXXX. The following is an excerpt from the DebugString() output:

  devices {
  device {
  device {
    din {
      value: "NEURIO--VAHXXXXXXXXXX"
    }
    serialNumber {
      value: "VAHXXXXXXXXXX"
    }
    manufacturer {
      value: "NEURIO"
    }
    componentParentDin {
      value: "STSTSM--1232100-00-G--TGxxxxxxxxxxxx"
    }
    firmwareVersion {
      value: "1.6.1-Tesla"
    }
    lastCommunicationTime {
      seconds: 1638768324
    }
    connectionParameters {
      ipAddress {
        value: "PWRview-XXXXX"
      }
    }
    deviceAttributes {
      meterAttributes {
        meterLocation: 5
      }
    }
  }
  }
  vitals {
  name: "NEURIO_CT0_Location"
  stringValue: "solarRGM"
  }
  }

Hi @slcasner - if you run this below, it looks like this is accurate. The ipAddress for the Neurio seems to be "PWRview-" with ShortID suffix. Using the /api/meters API call (not the protobuf /vitals data) you will see the same thing.

import pypowerwall
import json

pw = pypowerwall.Powerwall(host,password,email,timezone)
pw.poll('/api/meters')

Snip of Neurio section:

{
    "serial": "VAHXXXXXXXXXX",
    "short_id": "XXXXX",
    "type": "neurio_w2_tcp",
    "connected": true,
    "cts": [
        {
            "type": "solarRGM",
            "valid": [
                true,
                false,
                false,
                false
            ],
            "inverted": [
                false,
                false,
                false,
                false
            ],
            "real_power_scale_factor": 2
        }
    ],
    "ip_address": "PWRview-XXXXX",
    "mac": "xx-xx-xx-xx-xx-xx"
}

I suspect it is a local lookup name on the Tesla gateway.

OK, I guess the element names ipAddress and ip_address are just inappropriately chosen, then. To my mind, an IP address (for IPv4) should be a dotted quad numeric value.
