MQTT

By default all topics can be read without authentication. To publish to a topic an account is required.

If your team would like to publish statistics to MQTT please contact sysadmin@why2025.org

For graphing data in Grafana we support raw numeric values (without (SI) units). These simple values will be tracked in grafana with the full MQTT topic as the index name and `value` as the column name.

For flexibility reasons you can also send a datapoint with multiple values ("extended format"), add tags to your datapoint as well as send multiple datapoints in bulk. The extended format is a simple key-value JSON dictionary, or a JSON list of these when pushing multiple datapoints in bulk.

Examples of the extended format:

Single datapoint:

{
  "spacenet": 123,
  "why2025": 456,
  "why2025-2.5GHz": 10
}

Single datapoint with tags:

{
  "tschunk club mate": 100,
  "tschunk miomio mate": 200,
  "tags": {
    "bar": "Main stage"
  }
}

Multiple datapoints with tags:

[
  {
    "R": 230,
    "S": 232,
    "T": 231,
    "tags": {
      "generator": "A"
    }
  },
  {
    "R": 232,
    "S": 229,
    "T": 230,
    "tags": {
      "generator": "B"
    }
  }
]

Please note nested lists or dictionaries within the data point, outside of the "tags" key, are not supported and will not function.

As for the MQTT feed itself: we prefer to assign a prefix per team or project under the `why2025/` prefix.

Please publish data points with `retain` enabled, this will allow anyone to immediately receive the most recent data upon connecting to the MQTT server

Nextcloud Access

For accessing Nextcloud each team member will need their own personal account. Team:Sysadmin will create a main team folder (WHY2025/$TEAM) under which you'll be able to add your documents.

When requesting Nextcloud access:

• If you are a team lead: for which of your team(s) you want a shared folder to be created
• Indicate which teams you'll need access to, and which team lead we can validate the request with.
• If you request accounts in bulk: let us know both the nickname and associated mail address.

Services

For requesting services: please send a mail to our team mailbox and talk to us before deciding which software to deploy.

For suggestions: reaching out via either IRC or our team mailbox will work.
