Summary

Updated for v3 hardware version and improved WebUI.

Gerbers and BOM are included for ordering from JLCPCB.

Note this hardware version assumes a 44-pin ESP32 S3 DevKit. Refer to pinout included with schematics for details.

Improved ASCOM Alpaca compliance for dome/shutter error reporting. The controller now properly reports failures to ASCOM clients when the roof fails to move.

Changes

ASCOM Compliance

  • Slewing property now raises an exception (error 0x500) when in error state, per ASCOM specification
  • ShutterStatus correctly returns shutterError (4) and remains in error state until cleared
  • Added roofErrorReason for descriptive error messages returned to clients

Error Detection

  • Immediate error on start failure: If the source limit switch is still triggered after limitSwitchTimeout (default 5s), an error is raised immediately
  • Movement timeout error: If the roof starts moving but doesn't reach the destination within movementTimeout (default 90s), an error is raised
  • Both timeouts remain configurable via the web UI

Error State Handling

  • Error state is now "sticky" - won't auto-clear when limit switches are polled
  • Fixed race condition where clients could see Slewing=false instead of an exception during timeout
  • Added clearRoofError() function for explicit error recovery

Web UI

  • Added "Clear Error" button (appears only when in error state)
  • Button clears the error and re-checks limit switches to determine current position
