Desk research dated 2026-10-23; no physical tests or cybersecurity certification. Green runs official Home Assistant software. Standard local HTTP and ordinary account login are assessed; TLS, MFA and IP bans require appropriate configuration. The brute-force selection denotes available configurable protection, not a tested enabled setting. Historical exploit evidence concerns Green with the optional Music Assistant add-on, not an unconditional stock-device flaw. Date is the 2023-09-17 announcement/limited release. Incident labels describe published evidence rather than measured population rates; None means no qualifying incident identified in the stated search, not zero risk.
Physical tampering is an assessor rating of accessible reset/reflash interfaces and the physical-access requirement; it is not an incident-frequency statistic.
Release-date scope: Official announcement and limited anniversary release; wider distributor availability followed in November 2023.
Product status: In sale. Current manufacturer product page offers Home Assistant Green.
Proposed IDRS calculation under the assessment scope above: Device 2, System 3, User Authentication 2, total 7, grade C. Source methodology: https://fehmijaafar.net/wiki-iot/index.php/Methodology . This documentation-based rating is not an unconditional security certification.
Firmware scope: Official Home Assistant OS; storage source checked at OS 18.3. Default local HTTP and ordinary owner-account login assessed. IP-ban capability is explicitly configurable. Historical Music Assistant incident applies only when that optional add-on was installed.
