FAQ
How does PowerNotify tell the difference between a power cut and an internet outage?
When an outage occurs, the device briefly goes offline, which can happen during both power cuts and internet interruptions.
Once the device reconnects, PowerNotify looks at how that connection is restored. From this, it can identify whether the interruption was caused by a mains power loss or an internet-only issue.
Your restore notification will clearly explain which type of outage occurred, helping you quickly understand what happened without any guesswork.
Can I set it to alert me after X minutes?
Yes. The alert window is configurable per device in the cloud portal.
Can I have notifications going to different email addresses or phone numbers?
Yes. You can configure any number of email addresses or phone numbers to be alerted for each device.
Can I have multiple PowerNotify devices under one account?
Yes, you can have unlimited devices in your account, each with independent settings for alerts.
What’s the return policy?
We offer a 30-day return policy if you change your mind.
Does it work in any country?
Yes, PowerNotify works worldwide. The device connects via USB, and we currently support SMS and voice call alerts to over 200 countries.
