I have this old TP-Link smart lightbulb, it’s the only thing that’s IoT and on WiFi in my house.
Looking through pfBlocker logs for fun, and noticed it’s been trying to connect to the Tor network.
Oh! Also, it’s been uploading and downloading 100+ MB of data a day.
It’s just an NTP pool. The device is trying to update it’s time. Likely it made many other requests to other servers when this one didn’t work.
Maintaining up to date lists of anything is a game of whack a mole, so you’re always going to get weird results.
If you’re actually unsure, pcap the traffic on your pfsense box and see for yourself. NTP is an unencrypted protocol, so tshark or Wireshark will have no problem telling you all about it.
That said, I’d still agree with the other poster about local integration with home assistant and just block that sucker from the Internet.

Wait, it is? Pretty sure chrony.conf has some auth stuff in it.
Authentication != Encryption
You’re the one that connected an impossible-to-security-update device to the internet. You can do plenty of home automation without it needing to be that way, if you’re open to a little more setup being involved in the process.
It’s on it’s own VLAN from the beginning. Wanted to poke around but never got to it.
I still have it connected, want to use for practice.
I hope you update the post with any info you find.
