Decide what to replace, and what can wait
Replace what faces the internet first
Your router, cameras and network storage drives are reachable from outside your home, and attackers scan for old models automatically. These go to the top of your plan.
Contain what can wait
For a TV, printer, speaker or smart plug, pick one: move it to your guest Wi-Fi so it can't reach your computers and phones; turn off remote access in its app; block it from the internet in your router (a printer doesn't need it); or unplug it if you don't use it. Then tell HomeOS what you did with "I contained it".
Check before you buy
Look for how many years of security updates the maker promises. UK law has required makers to state this since April 2024, so many brands publish it on the product or support page. Prefer devices that update themselves and show their update status in the app. A US label for this, the Cyber Trust Mark, is still being set up and isn't in stores yet.
Buying used or refurbished? Check its end date
A bargain on last year's model can come with only months of updates left. Search the model name plus "end of support" before you buy, or add it in HomeOS after it arrives and we'll check.
Spread the cost
The replacement plan on your home report lists everything in order with a rough price, so you can do the urgent item now and the rest over the next few months.
Check your understanding
Which is more urgent: an old router or an old smart TV?
The router. It sits between the internet and every device you own. The TV can be contained on guest Wi-Fi.
What does "containing" a device mean?
Limiting what it can reach or what can reach it (guest Wi-Fi, no remote access, no internet) until you replace it.
