Compatibility notes

  • CSA lists Matter 1.2 certifications over Thread for firmware 1.1.00 (2025-02-11), 1.2.00 (2025-10-20) and 1.3.00 (2026-04-01) (csa-iot.org, read 2026-10-18).
  • Appears to be sold primarily in South Korea through LG's own store; no US/EU retail listing found (lge.co.kr, matteralpha.com, read 2026-10-18).
