Everything you need for safe operation
From UPS monitoring via SNMP or NUT to fully automated Hyper-V shutdown — completely automated end to end.
Hyper-V Automatic Shutdown
Connects via WinRM / PowerShell Remoting to any number of Hyper-V hosts. Gracefully shuts down all running VMs, then the host itself — in configurable order.
Windows Service
Installable as a Windows Service with autostart. Runs 24/7 unattended in the background — even without a logged-in user, ideal for server operation.
Alert Manager & Email
Email alerts via SMTP, Microsoft 365 App-only and Device Code Flow as well as SNMP Trap. Configurable triggers for power outage, low battery, shutdown start and power restored.
Automatic Updates
Built-in updater compares versions and updates all components from a UNC network path or HTTP server — with one click, including service restart.
One-time license — no subscription
Activate once, use forever. No monthly or annual fees — the license runs indefinitely. A simple activation by e-mail is all it takes. No subscription trap, no recurring charges.
Security & Encryption
All passwords are encrypted with Windows DPAPI. SNMP v3 with SHA/AES. WinRM optionally with SSL/TLS (port 5986). Single-instance protection via mutex.

Frequently Asked Questions
Everything important about the UPS Hyper-V Shutdown Monitor at a glance.
Which UPS manufacturers are supported?
The UPS Hyper-V Shutdown Monitor supports all UPS manufacturers that speak SNMP v1, v2c or v3 — including APC (American Power Conversion) with the PowerNet MIB, Eaton with manufacturer-specific OIDs, and all devices that implement the IETF standard RFC 1628 (UPS-MIB). Additionally, the NUT protocol (Network UPS Tools) via TCP port 3493 is supported, which is used by many other manufacturers.
What exactly happens during a power outage?
As soon as the UPS switches to battery operation, the tool monitors configurable thresholds (battery charge in percent and/or runtime in seconds). After a configurable number of consecutive confirmation polls (anti-false-trigger), the shutdown process is triggered: All Hyper-V hosts are processed in the defined order — for each host, all running VMs are first gracefully shut down via Stop-VM, then the host itself via shutdown.exe. Email alerts are sent immediately upon outage detection.
How do I set up WinRM access to Hyper-V?
On the Hyper-V host, Enable-PSRemoting -Force must be run once as administrator. If the tool runs on a different machine or in a workgroup, the host must be added as a TrustedHost: Set-Item WSMan:\localhost\Client\TrustedHosts -Value '192.168.1.10' -Force. The configured user requires membership in the "Hyper-V Administrators" group. A complete step-by-step guide is included in the app's FAQ window.
How do I set up Microsoft 365 email notifications?
For Windows Service operation, we recommend the App-only variant: Create an app registration in the Azure Portal, add the application permission Mail.Send in Microsoft Graph, grant admin consent and create a client secret. Tenant ID, Client ID and Secret are stored in the app. For interactive use, the Device Code Flow is available as an alternative. A detailed guide with screenshots is available in the app's FAQ window under "Azure AD / Microsoft 365".
Does the tool work without an internet connection?
Yes. The UPS Hyper-V Shutdown Monitor requires no internet connection for core operation. UPS communication takes place in the local network via SNMP or NUT, the Hyper-V connection via WinRM is also local. Only optional features such as Microsoft 365 email or the software updater (when configured with an HTTP URL) require an outbound network connection.
Can the tool manage multiple Hyper-V hosts simultaneously?
Yes, any number of Hyper-V hosts can be configured. Each host has its own connection configuration (IP, port, user, SSL) and a freely definable shutdown order. Hosts with a lower order number are shut down first. The shutdown process waits for each host to complete before starting the next one.
How does the trial work and what does a license cost?
After installation, the UPS Hyper-V Shutdown Monitor automatically starts as a 30-day fully functional trial — all features are unlocked, no registration or credit card required. After 30 days, UPS monitoring and emergency shutdown are blocked until a license is activated. For license prices and individual customizations, please contact .
