Not necessarily. Sometimes I turn off the adblocker for days and still have the requests when turning it back.

Adguard Home or Pi Hole, in a device that, indeed, can be a Raspberry Pi.

I have an adblocker for my home connection. By far, Hue subdomains are the most common blocked ones.

Philips Hue sends data to servers every few minutes.

Here is an approach: Kirika

I’ve been happily using it in the last two months, and you point made me worry for the first time. Thanks for it!

Try usememos.com with well-defined keywords. The search works well, the calendar view is helpful and It even has an integration using Open API.

Very simple and powerful tool.
