Internet Watchdog | Auto Router Rebooter | Fixes Frozen Internet | No Cloud, No Subscription | Vacation Rental & Smart Home Essential | Works with Home Assistant, OpenClaw & Local API

Your Router Freezes. Internet Watchdog Fixes It. Every router freezes eventually. It might be once a month or once a week, but when it happens, the only fix is to unplug it, wait, and plug it back in. If you're home, that's annoying. If you're traveling, managing a vacation rental, or relying on smart home cameras and locks — it's a real problem. PumpFuse Internet Watchdog plugs into the wall, your router plugs into it, and it handles the rest. The device monitors your internet connection by pinging three major DNS servers (Google, Cloudflare, and OpenDNS) every 60 seconds. All three must fail multiple consecutive checks before Watchdog takes action — this multi-target approach eliminates false alarms. When your internet is genuinely down, it waits a grace period (in case it recovers on its own), then power-cycles your router, waits for it to boot back up, and confirms the internet is working again. If the first reboot doesn't fix it, Watchdog has smart retry logic: it waits, tries again, and repeats up to three times. If the problem still isn't resolved — it's likely your ISP, not your router — the device stops retrying and alerts you with a solid red LED. No infinite reboot loops. No wasted effort. Setup takes 60 seconds. Plug it in, download the free PumpFuse app, connect via Bluetooth, enter your WiFi password, and you're done. No account to create, no cloud service, no subscription — ever. Why no push notifications? Because you don't need them. The Watchdog's job is to fix the problem automatically — not to tell you about it. By the time other devices send you a "your internet is down" text, the Watchdog has already power-cycled your router and restored service. But if you want alerts — outage detected, reboot started, internet restored, max retries exceeded, and more — the Home Assistant integration supports push notifications for all 9 event types with a single automation. See the MQTT & Home Assistant Reference for a ready-to-use YAML automation. For smart home enthusiasts: Internet Watchdog supports Home Assistant auto-discovery via MQTT, exposes a full local REST API (reachable via .local hostname — no IP address needed), and includes a built-in MCP server compatible with OpenClaw and other AI assistants.

• Auto-Fixes Frozen Internet — No More Manual Reboots. Continuously monitors your connection by pinging 3 independent DNS servers every 60 seconds. All must fail multiple consecutive checks before action is taken to help prevent false alarms. When your router becomes unresponsive, Internet Watchdog automatically power-cycles it and verifies the connection is restored before resuming monitoring. Operates 24/7 while you sleep, travel, or work.
• Smart Retry Logic — Prevents Rapid Reboot Cycles. Built-in grace periods allow your internet time to recover before any reboot. If the first restart does not resolve the issue, Watchdog waits 30 minutes and retries, up to 3 total attempts. If the problem persists, it stops retrying and provides LED and app indication. Designed to avoid unnecessary reboot loops and repeated power cycling.
• Scheduled Daily Reboots — Optional Preventative Maintenance. Set a daily reboot time, such as 4:00 AM, to refresh your router and help reduce slowdowns. Ideal for vacation rentals and short-term rental properties that require consistent guest WiFi. Uses the same controlled reboot process with connection verification.
• Free PumpFuse App — Setup in About 60 Seconds, No Account Required. Download the PumpFuse app for iOS or Android, connect via Bluetooth, enter your WiFi credentials, and complete setup in minutes. Monitor status, review event history, adjust settings, and trigger manual reboots from your phone. No cloud account, no subscription, and no ongoing service fees. For users who prefer notifications, compatible Home Assistant integration supports automation-based alerts for all 9 device events.
• Smart Home and Developer Ready — Local Control and Integration. Automatically discovered by Home Assistant via MQTT with 11 available entities including sensors, switches, and controls for automation dashboards. Includes a full local REST API accessible via device-specific .local hostname, eliminating the need to look up IP addresses. Built-in MCP server supports OpenClaw and other compatible AI assistants. Designed for local network control.
