From b39aa492cdee749212f3254743c7856f9c0e7bc2 Mon Sep 17 00:00:00 2001 From: maziggy Date: Mon, 12 Jan 2026 15:15:53 +0100 Subject: [PATCH] - Fixed chamber temperature badge on printer card for printers without chammber temperature sensor Fix Applied: 1. Added supports_chamber_temp() helper function that returns True only for X1/X1C/X1E, P2S, and H2 series 2. Modified printer_state_to_dict() to filter out chamber, chamber_target, chamber_heating from temperatures for unsupported models 3. Added model caching in PrinterManager so we can look up the model without a database query 4. Updated all callers (main.py, websocket.py) to pass the model The chamber temperature widget will now simply not appear for P1S/P1P/A1/A1Mini printers since the temperatures.chamber field won't be sent to the frontend. --- backend/app/api/routes/websocket.py | 4 +- backend/app/main.py | 2 +- backend/app/services/printer_manager.py | 56 ++++++++++- backend/tests/conftest.py | 9 +- .../tests/integration/test_printers_api.py | 1 + .../unit/services/test_printer_manager.py | 95 +++++++++++++++++++ 6 files changed, 160 insertions(+), 7 deletions(-) diff --git a/backend/app/api/routes/websocket.py b/backend/app/api/routes/websocket.py index a0f1beb52..24aa192cb 100644 --- a/backend/app/api/routes/websocket.py +++ b/backend/app/api/routes/websocket.py @@ -24,7 +24,7 @@ async def websocket_endpoint(websocket: WebSocket): { "type": "printer_status", "printer_id": printer_id, -
