Description

Adds a Push Notifications feature page, documenting the Notifications section added in mainsail-crew/mainsail#2665.

The page covers:

  • The two hard requirements that otherwise look like bugs: Mainsail must be served over HTTPS, and on iOS the Push API only exists once the web app has been added to the home screen.
  • Generating a VAPID key pair, with a warning to keep the private key outside the config directory — anything inside it can be downloaded through the file manager.
  • Subscribing a device, and using the local test notification to confirm the device displays notifications before any printer-side setup exists.
  • Sending from Moonraker's stock [notifier] through Apprise's vapid:// scheme, including why the body template needs two branches (job events fill event_args, remote-method messages fill event_message and leave event_args empty, so a template using only event_args raises).
  • The optional progress and filament-runout macros, which Mainsail hides unless they are present on the printer.
  • A troubleshooting table for the common failure modes.

Follows the style guide in AGENTS.md: second person, numbered steps, and the Interface Settings / cogs icon terminology. Registered in zensical.toml under Features, alphabetically between Printer Power Device and Query devices.

The screenshot is from a printer that has the optional macros installed, so all three sections are visible.

Related Tickets & Documents

Documents mainsail-crew/mainsail#2665. Best merged once that PR lands, since the feature is not in a release yet.

Mobile & Desktop Screenshots/Recordings

The page itself adds one screenshot, docs/images/features/notifications.png, showing the Notifications section on a mobile layout — the section is only listed on mobile, which the page states.

[optional] Are there any post-deployment tasks we need to perform?

None. If the mobile-only gate is dropped during review of mainsail-crew/mainsail#2665, one sentence on this page needs updating and I will follow up.

Comment thread docs/features/notifications.md Outdated
Addresses review feedback on mainsail-crew#61:

- The generator wrote private_key.pem into the current directory while the
  notifier example referenced ~/printer_data/webpush/, so following the page
  literally left the notifier pointing at a file that was never created. The
  command now creates and enters that directory first.
- The key was left at whatever the umask gave, typically world-readable.
  It is now chmod 600, and the warning says so.
- The NOTIFY example fence had no language identifier, which agent_docs/
  markdown-guide.md requires. Marked as gcode, and the shell block is now
  bash rather than sh to match the identifiers the guide lists.

Verified the documented command: it prints a valid base64url public key and
writes a loadable secp256r1 private key at mode 600.

…TPS origin

Mainsail now creates the VAPID key pair with WebCrypto when notifications are
first enabled, so the key generation script and the public key field are gone.

Adds a section on obtaining an HTTPS origin without putting a certificate on
the printer, using OctoEverywhere as the worked example -- verified against a
printer serving only plain HTTP on port 80. Notes that a push subscription
belongs to the origin that created it, so the web app must be installed from
the HTTPS address rather than the LAN one.

Replaces the note about keeping the key outside the config root: Mainsail can
only write through Moonraker, so both halves now live there and the trade-off
is stated plainly instead.

…nd macros

The page still described three manual edits that Mainsail now makes itself: a
[notifier] section in moonraker.conf, a macro file placed in the Klipper
config, and an include line for it in printer.cfg. All three are now written
and kept current by the Notifications settings, so the instructions become a
description of what happens rather than a list of things to do.

The macro block is the file Mainsail ships and writes, reproduced verbatim.
Its settings live in a _NOTIFY_SETTINGS macro, so the [save_variables]
requirement is gone.

Also: runout is now a present-to-absent transition rather than a static empty
reading, so the multi-material warning becomes an explanation of why enabling
every gate is safe; notes that the subscribe controls appear only in the
installed app while the printer-side settings and the device list appear
anywhere; and adds a Mainsail entry to the status-message options on the
Remote Access page, the one option needing nothing installed on the host.

Signed-off-by: Ricky Tsai <ricky@rtnztech.com>
The old one still showed the VAPID Public Key field, which no longer exists
now that the key pair is generated in the browser, and predated the connected
device list.

The new one is the whole section as the installed app shows it: the test and
subscribe controls, the print progress interval, a filament runout switch per
sensor with the toolhead on and the unused MMU gates off, and the connected
device list with its disconnect button.

Signed-off-by: Ricky Tsai <ricky@rtnztech.com>
Mainsail now writes started alongside complete, error and cancelled, so the
example section matches what it generates.

Signed-off-by: Ricky Tsai <ricky@rtnztech.com>
Mainsail writes all six of Moonraker's job events, so the example matches.
Pause and resume included: on a multi-material printer every tool change
that pauses the job will notify.
