Changelog

Dated changes to cells, confidence, and the site.

v1.05 — legal pages published and site opened to search; no rating changes (2026-10-18 SGT)

We published our legal pages and opened the site to search engines. Still no ads, no affiliate links, no analytics and no cookies. The “Preview · beta” label is removed.

v1.04 — prepared for future ads with reserved hidden ad spaces; no rating changes (2026-10-18 SGT)

We prepared the site for advertising later. No ads are shown yet, and no ad or third-party script loads. Reserved, clearly labelled “Advertisement” spaces stay hidden until ads are switched on and are sized to prevent page jumps when ads load.

v1.03 — moved to getmattercheck.com and tightened site security; no rating changes (2026-10-18 SGT)

We've moved the site to its permanent home at getmattercheck.com and made several behind-the-scenes security improvements. Nothing about the ratings, compatibility data, or device coverage has changed — this update is about where the site lives and how it protects your visit.

v1.02 — Google Home and Apple Home check on water leak sensors; no rating changes (2026-10-18 SGT)

Two cells (water leak sensors × Google Home and × Apple Home) were checked again for Google and Apple docs and dated 2026 tests of Matter leak sensors added directly to each app (not through a bridge), plus Amazon, SmartThings and Google Home follow-ups. No value changes and no confidence changes; both cells keep their values with newer sources or dated "nothing found" notes.

v1.01 — easier navigation and clearer pages; no rating changes (2026-10-18 SGT)

A design and navigation review of every page. No matrix values, confidence ratings or product entries changed.

v1.00 — Apple Home check on smoke / CO alarms and air quality sensors; no rating changes (2026-10-18 SGT)

Two Apple Home cells (smoke / CO alarms and air quality sensors) were checked again for Apple docs and dated 2025–2026 tests of Matter devices added directly to Apple Home (not through a bridge), plus Amazon, SmartThings and Google Home follow-ups. No value changes and no confidence changes; both cells keep their values with newer sources or dated "nothing found" notes.

v0.99 — Alexa check on smoke / CO alarms and air quality sensors; no rating changes (2026-10-18 SGT)

Two Amazon Alexa cells (smoke / CO alarms and air quality sensors) were checked again for Amazon docs and dated 2025–2026 tests of Matter devices added directly to an Echo (not through a bridge or skill), plus a SmartThings air quality follow-up. No value changes and no confidence changes; all three cells keep their values with newer sources or dated "nothing found" notes.

v0.98 — SmartThings and Home Assistant check on smoke / CO alarms and air quality sensors; SmartThings air quality confidence now Med (2026-10-18 SGT)

Four cells (smoke / CO alarms and air quality sensors on SmartThings and Home Assistant) were checked again for official docs and dated 2025–2026 tests of Matter devices added directly (not through a bridge). No value changes and one confidence change; the other three cells keep their values with newer sources.

v0.97 — Google smoke / CO and Script Editor check; air quality as a Google starter is now Partial (2026-10-18 SGT)

Three Google Home cells (smoke / CO alarms, air quality sensors and pressure sensors) were checked again for official docs and dated 2025–2026 tests, looking for a second review of a Matter smoke + CO alarm added directly to Google Home and for automation starters that only work in Google's Script Editor. One value and one confidence change; the other two cells keep their values with newer sources or dated "nothing found" notes.

v0.96 — Google Home and Home Assistant evidence refresh; light level as a Google starter is now Partial (2026-10-18 SGT)

Google Home and Home Assistant cells that had no recent hands-on report of a Matter device added directly (not through a bridge) were checked again for official docs and dated 2025–2026 tests. One value and one confidence change; the other 21 cells keep their values with newer sources or dated "nothing found" notes.

v0.95 — Can a thermostat, fan or robot vacuum start an Alexa routine? Still unknown, no rating changes (2026-10-18 SGT)

The ten Alexa cells whose trigger was still unknown were checked again for Amazon docs and independent tests of Matter devices added directly to an Echo, mainly looking for a thermostat, fan, air purifier or robot vacuum that starts a routine (not one that a routine switches). No value or confidence changes. All ten triggers stay unknown.

v0.94 — Can a thermostat, fan or air purifier start an Apple Home automation? Still unknown, no rating changes (2026-10-17 SGT)

The two Apple Home cells whose trigger was still unknown were checked again for Apple docs and independent tests of Matter devices added directly to the Home app, looking for a thermostat, fan or air purifier that starts an automation (not one that an automation switches). No value or confidence changes. Both triggers stay unknown.

v0.93 — Can a window shade start an automation? Cross-platform check, no rating changes (2026-10-17 SGT)

All five window covering cells were checked for official docs and independent tests of Matter shades added directly to each app, mainly to see whether a shade opening or closing can start an automation, and whether automations can move a shade. No value or confidence changes. No independent test of a Matter shade starting an automation was found on any platform, so where the trigger is rated it rests on each platform's own docs.

v0.92 — Wall switches with Matter buttons: two Inovelli switches re-filed, Aqara W100 listed under buttons, two GE Cync switches added (2026-10-17 SGT)

Some wall switches and sensors also show their physical buttons to Matter apps as separate button devices. This pass checked every light, plug and switch SKU for those extra button endpoints and for the device type that actually switches the load. No matrix value or confidence changes.

v0.91 — Alexa motion, window covering and contact sensor recency check, no rating changes (2026-10-17 SGT)

Three Amazon Alexa cells rated High were rechecked for newer independent tests of Matter devices added directly to an Echo (not through a maker's hub or Alexa skill). No value or confidence changes; all three stay High.

v0.90 — Tapo S505 and Aqara Light Switch H2 US moved from buttons to the on/off light row (2026-10-17 SGT)

Two in-wall switches that switch a light circuit were still filed under Matter button (switch_button). CSA's certification ledger lists both as Matter On/Off Light, so under the v0.89 rule they now sit in the on/off light row, like the Kasa KS205. The Aqara H2 US is also still listed on the button page, because its extra buttons show up in Matter as separate buttons that send a single press. No matrix values or confidence changed; SKU confidence unchanged (High).

v0.89 — Button control/action rule made consistent: action Partial→N on three platforms, Google control N→Partial (2026-10-17 SGT)

The Matter button (switch_button) row used two meanings for control (C) and automation action (A): some cells counted wall switches that switch a load, others treated the row as buttons. MatterCheck now uses one rule (see methodology, "Switches and buttons"): C = Partial when the button shows in the app as its own device but nothing on it can be operated; A = N because a Matter button has no commands. Buttons still start automations (T). Pairing, triggers and confidence are unchanged; all five cells stay High.

v0.88 — Button multi-press audit across all five platforms, no rating changes (2026-10-17 SGT)

All five Matter button (switch_button) cells were rechecked for which press types — single, double, long press, release, three or more presses — work as automation triggers in each consumer app, against official pages and independent tests of Matter buttons (mostly the IKEA BILRESA) added directly to each platform. No value or confidence changes; all five stay High. SmartThings and Home Assistant were High on official pages alone and now have independent tests attached.

v0.87 — Alexa button Med→High, leak and contact settle pass (2026-10-17 SGT)

The three Amazon Alexa cells left open by the v0.85 audit (button, leak sensor, contact sensor) were rechecked against Amazon's Matter documentation and independent tests of Matter devices added directly to Alexa. One confidence change: switch_button × amazon_alexa Med→High. Leak and contact sensor values are unchanged.

v0.86 — Thermostat automation settle pass, no rating changes (2026-10-17 SGT)

All five thermostat cells (rated Med since the v0.81–v0.85 audits) were rechecked against each platform's automation help pages and independent reviews that add a Matter thermostat directly to the platform (Aqara W200, Nest Learning Thermostat 4th gen, Honeywell X2S/X8S, Tado X, Eve, Mysa). No value or confidence changes; all five stay Med.

v0.85 — Alexa leak trigger N→Unknown and button High→Med, Alexa High-bar audit (2026-10-17 SGT)

All six amazon_alexa cells that were still High were audited against Amazon's Matter categories table, the Alexa.SimpleEventSource doc (modified 2026-09-30) and independent dated reviews of Matter devices added directly to Alexa; the other 18 Alexa cells were already Med. 2 changes: leak × amazon_alexa automation_trigger N→Unknown, High→Med — Amazon still maps the Matter water leak detector to no Alexa feature, but PCMag (2026-03-16) added a Shelly Flood Gen4 (a certified Matter water leak detector) to Alexa with its Matter code and says a water-detected Alexa routine turned off a smart plug reliably; Shelly's own Alexa skill could also explain that routine, so this is recorded as Unknown, not Yes. switch_button × amazon_alexa High→Med (values unchanged) — Amazon says button presses can start Alexa routines, but only forum and Reddit users (IKEA BILRESA, single press only; double and hold count as single) confirm it, with reliability complaints and no independent review. Kept High with native hands-on: contact_sensor (NotEnoughTech 2024-04-11 + Pocket-lint 2024-05-12; no 2025–2026 Alexa test found yet), motion_occupancy (Frank's Easy Tech Corner 2026-03-31), window_covering (PCMag 2025-05-25 + Wirecutter 2026-05-08), pressure_sensor (Espressif native test 2026-07-23, still N). This completes the per-platform High-bar audits. Matrix High 82 / Med 38 / 12 Unknown.

v0.84 — Home Assistant thermostat High→Med, Home Assistant High-bar audit (2026-10-17 SGT)

Six home_assistant cells that were High on the Home Assistant Matter integration page alone were audited against Home Assistant's consumer automation docs (binary sensor, sensor, switch, lock and climate triggers and actions), Works with Home Assistant certifications (Eve 2025-04-29, Nuki 2025-07-03) and independent dated reviews of Matter devices added directly to Home Assistant. 1 confidence change: thermostat × home_assistant High→Med (P/C/T/A stay Y/Y/Y/Y) — Home Assistant documents thermostat triggers and actions, but independent reviews (ChrisHansenTech Aqara W200 2026-04-18, thesmarthome.blog Eve Thermo 2025-08-11) only show pairing and temperature control; none tests a Matter thermostat in an automation. Kept High with native hands-on attached: motion_occupancy (Teknik i Hemmet MYGGSPRAY 2025-12-31, TechteamGB 2026-02-20, Aqara W200 presence used as an automation trigger 2026-04-18), temp_humidity (Teknik i Hemmet TIMMERFLOTTE 2026-07-19), plug_outlet (chrissmart.de GRILLPLATS with tested automations 2026-08-11 + AnalisisGadgets 2026-05-18), door_lock (raspberry.tips Nuki Smart Lock Ultra 2026-09-16 + Derek Seaman Aqara U200 2024-07-13), contact_sensor (Techtest MYGGBETT 2026-01-28 + Teknik i Hemmet 2026-01-01). Thermostat is now Med on all five platforms. Matrix High 84 / Med 36 / 11 Unknown.

v0.83 — SmartThings thermostat High→Med, SmartThings High-bar audit (2026-10-17 SGT)

Six smartthings cells that were High on the SmartThings partners page and hub/Edge release notes were audited against SmartThings consumer IKEA Matter FAQ (2026-09-28) / blog (2026-04-20) and independent dated reviews of Matter devices added directly to SmartThings. 1 confidence change: thermostat × smartthings High→Med (P/C/T/A stay Y/Y/Y/Y) — partners lists Thermostat and the Edge thermostat driver exists (developer path), but no independent review shows a Matter thermostat working end-to-end in SmartThings; Matter Alpha's Honeywell X2S test (2025-06-26) paired over Matter but setpoint changes failed and automations did not work. Kept High with native hands-on attached: motion_occupancy (Techtest MYGGSPRAY 2026-02-11 + Rental Home Automator 2026-02-24), temp_humidity (Techtest TIMMERFLOTTE 2026-02-01), plug_outlet (Rental Home Automator GRILLPLATS 2026-09-23), door_lock (The Verge Kwikset Halo Select 2025-06-13 + Level Lock Pro 2025-08-26), contact_sensor (Rental Home Automator MYGGBETT 2026-02-24). Matrix High 85 / Med 35 / 11 Unknown.

v0.82 — Google Home thermostat High→Med, Google High-bar audit (2026-10-17 SGT)

Six google_home cells that were High on two Google developer pages only audited against consumer help 15684394/13127223 + independent dated native Matter hands-on. 1 confidence change: thermostat × google_home High→Med (P/C/T/A stay Y/Y/Y/Y) — official consumer page names thermostat local-temperature starter (2025-09-10) and set mode/temp action (2025-10-01), but no independent native Matter→Google Home thermostat hands-on (Mysa vendor-only; Nest 4th gen is Google-native in GHA; W200 forum pairing/Celsius bug only). Kept High with native hands-on attached: motion_occupancy (Android Police Matter occupancy trigger 2026-08-03), temp_humidity (How-To Geek TIMMERFLOTTE 2026-02-02), plug_outlet (9to5Google KP125M 2023-05-25 + Android Police Eve Energy 2026-05-02), door_lock (9to5Google Yale Matter 2025-09-22 + Verge Level Lock Pro 2025-08-26; Partial C/A for PIN/remote-unlock policy unchanged), contact_sensor (Android Police Eve door trigger <1s + Matter Alpha Eve 2024-07-22). Matrix High 86 / Med 34 / 11 Unknown.
