Manual Z-Wave Outlet Restart (Router Reboot)

Open your Home Assistant instance and show the blueprint import dialog with a specific blueprint pre-filled.

A robust, safe Home Assistant blueprint designed to automate a controlled power-cycle sequence for network routers or modems using a Z-Wave smart plug, featuring dynamic duration estimates, cooldown stabilization, trigger resets, and optional mobile notifications.

:warning: Prerequisites & Important Warning:

  • Z-Wave Mesh: Ensure you use a reliable Z-Wave smart plug that can maintain its connection or recover cleanly when power is cut.
  • Hardware Safety: Do NOT use a regular non-Z-Wave plug or apply this blueprint to sensitive equipment requiring a graceful shutdown (such as a NAS or computer running filesystems). This blueprint is designed for hard power-cycling routers, modems, or network gear.
  • Trigger Helper: Create a toggle helper (input_boolean.*) or dedicated switch in Home Assistant (Settings > Devices & Services > Helpers) to act as the restart trigger button.

Features

  • Controlled Power Sequence: Powers down the outlet, waits for a user-specified duration (default: 30s), restores power, and enforces a stabilization cooldown before concluding.

  • Single Execution Guard (mode: single): Prevents overlapping restart cycles if the trigger helper is flipped multiple times while a reboot process is actively running.

  • Dynamic Duration Math: Uses Jinja2 templates to automatically calculate and display the total cycle duration inside the initial start notification based on your custom slider inputs.

  • Auto-Resetting Trigger Entity: Automatically turns off the trigger entity (input_boolean or switch) at the end of the cooldown period so it is always ready for the next manual restart.

  • Mobile Push Notifications: Sends customizable push notifications before the restart begins and after the cooldown cycle completes (optional).

  • Operation Summary:

    Event Action Taken
    Trigger Switch Flipped on Sends optional start notification with calculated cycle duration.
    Power Cut (switch.turn_off) Turns off the Z-Wave outlet for the defined off_duration seconds.
    Power Restored (switch.turn_on) Turns the Z-Wave outlet back on and holds for the cooldown_duration minutes.
    Cycle Completed Resets the trigger entity back off and sends the optional completion notification.

Blueprint Inputs

Input Description Required? Default
Trigger Entity The input_boolean or switch entity used to initiate the restart. Yes N/A
Z-Wave Smart Plug The Z-Wave plug or switch connected to your router/modem (switch.*). Yes N/A
Power Off Duration (Seconds) How long to keep the outlet powered off before restoring power. Yes 30
Cooldown Duration (Minutes) Stabilization delay after restoring power before resetting trigger and notifying. Yes 5
Notification Target (Optional) Mobile device target (mobile_app_*) for push notifications. Leave empty to disable. No ""
Start Notification Title Custom title for the initial restart push notification. No "Reboot Triggered"
Start Notification Message Custom body text sent at start (cycle timing is automatically appended). No "Internet connection will be temporarily interrupted."
Completion Notification Title Custom title for the completion push notification. No "Reboot Completed"
Completion Notification Message Custom body text sent when the full cycle concludes. No "Network connectivity should be restored."

:light_bulb: Important Notes & Pro-Tips

  • Notification Delivery Delays: Push notifications sent through the mobile app rely on external cloud messaging services (FCM/APNs) and mobile OS background processes. If your phone is in Doze/Low Power mode or if local network routing transitions right as power cuts, push notifications may arrive with a slight delay. The notification timestamp tracks automation initiation, not necessarily instant mobile push arrival.
  • Cycle Duration vs. Router Boot Time: The calculated total duration in the start notification (cooldown_duration + off_duration) represents the script execution time and plug power state. Actual router hardware boot times may vary depending on your network gear.
  • Concurrent Trigger Prevention: Because the blueprint utilizes mode: single and maintains the trigger entity in an on state throughout the entire sequence, accidental manual toggles while a reboot is active will be safely ignored.
  • Error Resiliency: Notification calls utilize continue_on_error: true so that network or mobile service errors will never prevent the plug from restoring power or finishing its cycle.
