v0.2.1

Fixed

• Settings screen: each printer's fields now form one group. Before, Sensors, Advanced and
  the name/host fields each acted as a separate printer, so the screen showed values from a
  blank entry (for example a 60 s poll interval when 10 was saved) and saved empty printer
  rows. Remove any empty printer rows left in your config.
• Port, poll interval and offline count are number boxes instead of sliders.

v0.2.0

More Brother printers: color lasers, inkjets and older models.

Added

• Color lasers: toner per color, drum per color, belt, fuser, laser unit and paper feed kits.
• Inkjets: ink per color and the ink waste box. Toner wording becomes Ink.
• The battery shows the lowest color, and turns low when any color reaches the threshold by
  either reading, or when the printer flags low toner.
• Toner / ink tiles: one per color on color printers.
• SNMP v1 for older printers (snmpVersion, automatic by default).
• Printers that report no levels (older and ink tank models) get no battery instead of 0%.
• Warnings in the log when the drum or another part nears end of life.
• Problem log lines name the condition (cover open, paper jam...).
• Page count from mono + color counts on inkjets that don't report a total.

Changed

• Status text is decoded in the printer's character set, so non-English displays read
  correctly. Problems and printing rely on language-neutral status codes first.
• Model and serial also read from Brother's own records, for printers without the
  standard ones; page count falls back to the Printer MIB.
• When coarse levels tie (they move in 10% steps), the finer reading picks the lowest
  color, so the battery names the color that is actually running out.
• Tested against SNMP captures from 14 Brother models.

v0.1.4

First public release.

Added

• Printing state as an occupancy sensor, from hrPrinterStatus and the printer's display.
• Printer Problem contact sensor that opens on a jam, open cover, empty tray or other error.
  Apple Home doesn't show Status Fault on occupancy sensors.
• Toner % as a battery level with a configurable low threshold, read from Brother's own
  SNMP records rather than the standard Printer MIB.
• No Response in the Home app while the printer can't be reached, recovering when it answers.
• Optional toner tile (humidity sensor) and optional drum-life battery.
• Page count as a custom characteristic.
• brother-printer-probe command to check what a printer reports.
• Settings screen, tests and linting.

Changed

• Drum life is off by default: Home shows one battery per accessory and was showing the
  drum instead of the toner. The drum is still read and warned about in the log.
• Settings screen no longer reports a validation error for the blank printer row it adds.
  Rows without a host are ignored, with a warning only if they were filled in.
