## Questions & Answers

**Q: How does the device send a message if wi-fi in building is off due to power outage without a sim card?**
A: The way that this works is, the device sends a message every few minutes to a remote server (in Italy) while it is in a healthy state. If the remote Server doesn’t receive a healthy message then the server notifies you. Therefore it doesn’t rely on your Wi-Fi when the power is out.

**Q: Do you just plug it into any usb port ?.**
A: I plug the device into a USB port of a 13a spur socket (but any USB port will do) All that is important is the device is powered from a USB port which is always powered up.  The host will recognise when the local WiFi network the device is attached to cannot communicate with the device (because of a power failure) and the host will send the notification email. Hope this helps.

**Q: Can i plug this into the usb port on my tv? if tv is turned off but still connected to power supply that is on will i get an alert**
A: Dear Customer, if the USB port will be ON when the TV set is OFF, it is ok. Otherwise you will get an alert.

Please take into consideration that our device should be close to the WiFi router, to have a stable WiFi connection. So you can also plug our device in the router USB port.

Best regards, 
ControlloCasa srl

**Q: Are there any ongoing fees or charges**
A: Dear Customer,
no there are not.

The provison of alert by email is free of charge.

In case you would like to add alert by phone call, there is an annual subscription.

For any other question don't hesitate to contact us again.

Best regards,
ControlloCasa Team

### ⭐⭐⭐⭐ It does what it says on the box!!
*by C***W on 24 January 2025*

I went on holiday a few years ago and came back to a defrosted fridge & freezer!!! A trip had gone on my fuse board I found this unit on Amazon. If you loose power it sends a email to you free or if you want a text it will cost you £15 a year. Well worth the piece of mind knowing you can monitor it and take action if you need. I've tested it and it works really well.
