Questions?
Do I need Wi‑Fi?
No. Powy sends its alerts over the cellular network, so it keeps working when the internet is down.
What happens when the power goes out?
Powy has built-in backup power, so it can still send the alert. The buzzer also sounds an alarm.
When do I get a temperature alert?
When the temperature goes outside the limits you set in the app. You can choose any value between −20°C and 70°C, for example an alert at 10°C.
Can I use Powy in my Home Electrical Panel?
Yes. Powy Pro AC clicks onto the DIN rail in your Home Electrical Panel and alerts you when a group or the whole house loses power. Have it installed by a qualified electrician.
