Feature: Custom Support info

[proddy]

The current Help page shows

• links to the wiki, discord and how to submit a request or report a bug in GitHub.
• download links for support information and all values
• a footer asking everyone to like the project in GitHub

The change

1. For users that have a "guest" role, they don't have access to many of the Settings so this information above should only be shown for "admin" users.
2. Allow for customized support information to be shown at the top of the Help page. You can upload a "support.json" file that contains some keys including "support_text" and "image_url" that are rendered in a 2-column table. This data is permanently stored in EMS-ESP and loaded at boot. If the file is not present, or badly formatted it will not be shown.
3. Remove the footer. I think people know it's open-source.

1 in 3.7.0
2 to customize it via a JSON we'll add to 3.7.1

Add 2 and 3 to 3.7.0.

You can create a JSON file like:

{
  "type": "customSupport",
  "Support": {
  "html": [
    "This product is installed and managed by:",
    "",
    "<b>Bosch Installer Example</b>",
    "",
    "Nefit Road 12",
    "1234 AB Amsterdam",
    "Phone: +31 123 456 789",
    "email: [email protected]",
    "",
    "For help and questions please <a target='_blank' href='https://emsesp.org'>contact</a> your installer."
  ],
    "img_url": "https://emsesp.org/_media/images/designer.png"
  }
}

and upload it via the WebUI. It will be displayed in the Help page for both Admin and Guest users
