### ⭐⭐⭐ ハズレあり
*by A***ー on January 26, 2026*

当たり・ハズレあり、ハズレ率約２割。当たりは良好、ハズレは奇想天外。

### ⭐⭐⭐⭐ Matterに対応しているからこそ
*by オ***！ on September 24, 2024*

「SESAMI 5 Pro」というスマートロックの開閉センサーとして購入しました。 Switchbot社の開閉センサーではGooglehomeで他社製品を制御、操作出来ないとの事で、Matterに対応しているこの製品を選んだ。 Googlehomeに追加しても開閉の判断が可能で、オートメーションにも組み込むことが出来る。 お陰で目的であったスマートロックの開閉センサーとして使用出来た。

### ⭐ Thread対応前提
*by 葉***山 on January 16, 2025*

さもMatter対応の機器と直接接続できるような記載があるが 厳密にはMatter Thread対応機（Echoなどでも一分のまだラインナップは少数。）のみとなるため AlexaやスマートロックとつなげるにはMatter Thread対応Hubが必要。 EchoSpot ＋ Thered対応Hub ＋ 本センサー + スマートロック の構成になる。 仕方なく同一メーカーのAqaraのThered対応 M3Hub を購入したが Alexa Aqara Home どちらとも接続ができない。 何度も接続を試すもの、AlexaはWifiに接続不可。 AqaraHomeアプリは、何度もQRコードを読む画面にループバックして成功しない。 IPV6を切ってIPV4にしたり Wi-Fiを2.4Ghzにしたり ルーターを別のものに変えても追加ができなかった。 （ハブを認識検知するが、アプリ接続連携ができない。） 2時間かかって原因の切り分けもできないため返品。 全くもっておすすめできない。
