For over a decade Philips Hue offered lights that work without sharing your data to the cloud. This is changing soon and we need your help to make some noise to convince them to revert this decision.

[Update Oct 2: data sharing to become optional] Philips Hue will force users to upload their data to Hue cloud

To control your lights you soon need to create an account and share your data with the Hue cloud.

@homeassistant In fact, nowadays, my Adguard Home instance blocks a lot of telemetry connections to a Philip's servers from my Hue's bridge.
@koman @homeassistant which domains do you block? Could you share the rules?

@beyondwatts @homeassistant

The blocked domains were:

diag.meethue.com (this one was constantly connecting to the server every minute)

ntp2.aliyun.com (you used to be able to disable time synchronization in the bridge's settings years ago, but now you can't)

ecdinterface.philips.com

mqtt.2030.ltsapis.goog

However, I mentioned "were" at the beginning because since July 27, my bridge hasn't been sending any data to the Internet. Maybe there's a new firmware. Who knows?
