Data quality and evidence coverage

Current source coverage

Publication mode: REAL EPA DATA — FULL COUNT-VERIFIED API SNAPSHOT. Real source snapshot; published claims remain limited to documented evidence.

Snapshot time: 2026-11-05T22:37:32.529114+00:00. Hardware references reviewed: 2026-11-05.

Commercial ice machines: real source audit

Official dataset: ENERGY STAR commercial ice machines.

• Raw source rows received: 651
• Unique usable models: 628
• Rejected rows: 0
• Duplicate model keys: 23
• Complete count-verified upstream snapshot: yes

Output is normalized for comparable production, electricity and water units. These data do not provide retail prices, on-site yield guarantees, local certification or dealer stock. See our source-backed analysis.

Commercial refrigeration: separate source audit

Import status: ok. Count-verified EPA refrigerator/freezer model rows: 1994. A zero count while unavailable is not evidence that no certified products exist.

Home Assistant: documented integration scope

Source: Zigbee2MQTT supported devices.

Import status: ok; source-attributed device entries: 5865.

Zigbee2MQTT device documentation does not independently establish ZHA, Z-Wave JS, Matter, coordinator firmware, hardware revision, gateway or regional certification compatibility. Ambiguous aliases are kept distinct for review rather than combined into false support claims. Explore documented device features.

Separate licensed Matter certification references: 0; source status: unavailable. These are not tests of Home Assistant pairing. Inspect Matter certification sources →

PC hardware: preliminary compatibility evidence

Current sample: 6 official manufacturer spec references, reviewed 2026-11-05. Our preliminary matrix evaluates 9 CPU/board combinations: 4 are conditional candidates and 5 have documented constraint conflicts, and 0 have insufficient evidence. Zero are certified as fully compatible.

Additional exact-model GPU/case evidence references: 2; preliminary fit comparisons: 1. These do not constitute measured builds. Inspect the GPU/case example.

Separate, not compatibility-verified: 126 attributed CC BY 4.0 PC research candidates, 97 with individual source references. Browse the isolated candidate index. These are NOT additional manufacturer-reviewed compatibility verdicts.

Socket, broad family and memory technology can be compared, but the exact motherboard CPU support list, installed BIOS, RAM QVL, power quality and physical fit require more evidence.

Integrity principles and open limitations

• Source specifications are evidence of what a publisher documents, not independent laboratory testing.
• Device, component and merchant SKU aliases can be ambiguous; exact identity takes priority.
• Missing compatibility documentation is not a positive result.
• Affiliate partnerships never change compatibility verdicts or utility calculations.
• A model's presence does not prove it is available for purchase in a specific country.
