✅ Raspberry Pi Zero 2 W + DVSwitch Dashboard

「Hardware Info → Platform」を正しく表示する！

🎯 なぜ正しく表示する必要があるの？

DVSwitch Dashboardの「Hardware Info → Platform」は、機器の識別と保守性の要です。\ ここが「Unknown ARM based System」のままだと…

• 🔍 トラブルシュートが難しい：機種特定できず、原因切り分けに時間がかかる
• 🛠 保守性が低下：温度管理や性能差に気づきにくい
• 📦 構成管理が不正確：複数台運用時に混乱しやすい

原因：古い判定スクリプトが最新Raspberry Pi（Zero 2 Wなど）を認識できないため。\ 解決策：Raspberry Piが提供する Device Treeのモデル情報を使って、確実に表示！

✅ 対象環境

• Raspberry Pi Zero 2 W（ARMv7）
• OS：Debian GNU/Linux 11 (bullseye)
• DVSwitch Dashboard（/var/www/html/include/system.php）
• Webサーバ：lighttpd

🚀 手順（バックアップから表示確認まで）

STEP 1：既存スクリプトをバックアップ

sudo cp /usr/local/sbin/platformDetect.sh /usr/local/sbin/platformDetect.sh.bak.$(date +%F)

例：platformDetect.sh.bak.2025-12-04

STEP 2：新しいスクリプトを作成

sudo nano /usr/local/sbin/platformDetect.sh.new

以下をコピペして保存（POSIX sh互換・安全版）：

# --- 5) Final fallback: generic arch label ---
echo "Generic $(uname -m) class computer"
exit 0

STEP 3：権限を付与

sudo chmod 0755 /usr/local/sbin/platformDetect.sh.new

STEP 4：動作確認

/usr/local/sbin/platformDetect.sh.new

# → Raspberry Pi Zero 2 W Rev 1.0

sudo -u www-data /usr/local/sbin/platformDetect.sh.new

# → 同じ結果ならOK

STEP 5：置き換え

sudo mv /usr/local/sbin/platformDetect.sh.new /usr/local/sbin/platformDetect.sh

STEP 6：Webサーバ再起動

sudo systemctl restart lighttpd

STEP 7：Dashboardをハードリロード

• ブラウザで Ctrl+F5
• 「Hardware Info → Platform」に\ ✅ Raspberry Pi Zero 2 W Rev 1.0 が表示されれば成功！

🔍 トラブルシュート

• PHPのexec()が無効 → php.iniでdisable_functionsを確認
• 権限問題 → sudo -u www-data /usr/local/sbin/platformDetect.shで確認
• dashで失敗 → この版はPOSIX互換なのでOK！
