Product notes
ANNOUNCEMENT / pre-ship. Apple shop: pair with LG Smart Thermostat or other Matter-compatible thermostats in Home app for multi-room comfort. Measures temperature and humidity. Magnetic/adhesive mount. Non-Apple Matter fabrics: Unknown until ship.
Recheck: CSA has LG Temp and Humidity Sensor (TMSTAA4W, CSA261G7MAT51287-24) but not TMST2A6W model match. Keep Med. v0.54 recheck 2026-10-16: DCL LG VID 0x102E temp/humidity entry is still TMSTAA4W only (PID 0x2000, productUrl lge.co.kr); no TMST2A6W. Keep Med. Missing: TMST2A6W Matter cert. v1.15 (2026-10-19): removed the per-product December 2026 shelf date, which no source gave for this model. Apple: Home Collection availability 'begins in December, with select accessories available starting early 2027' (Newsroom 2026-10-13; Apple doesn't say which). Apple shop page (read 2026-10-19): 'Coming later. Check back for availability.'
How it differs from the type answer
- Explicit Home-app pairing to Matter thermostats for room-balance is ecosystem delta vs standalone temp_humidity cell.
- Med: model from FCC/MacRumors + Apple shop + Newsroom Matter claim; pre-ship.
- Note: older unrelated LG CSA Temp/Humidity Sensor TMSTAA4W (Matter 1.2) is a different part — do not conflate.
