A Noisy Smart Appliance Isn't Always Leaking Data

A smart bulb or coffee maker can send lots of messages over your home network. A big number on your router's screen does not tell you what those messages contain.

The device might be sharing data with a company. It might also be downloading an update, trying again after an error, or talking to other devices inside your home.

Datante helps you review requests for internet service names and block selected tracking connections. It does not measure every message or fix a faulty appliance.

What is a smart device?

A smart device can connect to a network and use software to provide extra features. You may see these devices called IoT: the Internet of Things.

Your home network is the connection between your devices and your router. The router is the box that connects them to the internet.

Some messages stay inside your home. Others go out to online services. A cloud service simply means a service running on computers elsewhere, reached over the internet.

What does a big traffic number mean?

Network traffic means data moving between devices or services. Different tools count different things:

• A Wi-Fi counter may include messages that stay inside your home.
• An internet counter may measure data leaving your home or coming in.
• An address-lookup report counts address questions and filtering decisions.

DNS stands for Domain Name System. It helps devices find a network address for a name, such as example.com. Asking for the address is a DNS lookup.

These counts are not the same. Thousands of address questions do not prove that a device uploaded a large amount of private data.

Before reacting to a story about one coffee maker or bulb, check what was measured. One home's problem does not prove all appliances behave the same way.

How does Datante help you check?

A domain is the name of a website or online service. Datante can show household lookups for those names and whether its rules blocked or allowed them.

That helps you spot repeated lookups for selected advertising or tracking services.

If a device asks Datante for a name covered by an enabled blocking rule, Datante can stop the usual lookup. That may stop a new connection that needs the answer.

Setting up the router can extend this filtering to compatible devices using the assigned settings. You do not need a browser blocker on each appliance.

A report may group activity by device family when there is enough evidence. It is not a complete list of physical devices. A brand-related domain does not identify one exact appliance.

Will Datante stop a device slowing down my Wi-Fi?

Not necessarily. A faulty device may keep sending messages inside your home to an address it already knows. DNS filtering cannot reliably stop that.

It also cannot read the contents of every protected connection or prove that a company received a particular file. It cannot install a fix for broken device software.

A device may remember an address instead of looking it up again. That is called caching. It may also connect directly to an IP address, which is a network address, or use another DNS service.

If you need to cut off a device completely, use the right router controls or disconnect it safely. Blocking a few names is not the same as cutting off all access.

What should you do first?

1. Check whether the number measures home Wi-Fi, internet data or DNS lookups.
2. Check which device the tool identifies. Do not guess from a brand name alone.
3. Find out which features need internet access, such as alerts or updates.
4. Install updates from the device maker. Review what its phone app can access.
5. Check whether your router offers a separate smart-device or guest network. It must actually keep devices apart to provide that benefit.
6. Review specific lookups in Datante. If blocking causes a problem, investigate it rather than allowing everything.

The U.S. government's 2019 smart-device safety guide recommends updates, passwords that are hard to guess and not reused, permission checks and a separate network for connected devices.

Do not experiment by disconnecting medical equipment or devices people rely on for safety. A camera may also lose alerts. Get the right support before changing access that someone relies on.

Frequently asked questions

Can Datante tell me how much data an appliance uploaded?

DNS counts are not a measurement of total uploaded data. Use your router's traffic tools for that.

Does a blocked name prove my appliance has been hacked?

No. Normal software can contact names you choose to block. A block decision does not prove an infection.

Should I disconnect every smart device?

That depends on what you need it to do. Some need online services for useful features and updates. Check the maker's guidance first.
