Can’t it just beep?

No, it should definitely not need to talk to Samsung to share basic information with your homeassistant

Have you captured the data with Wireshark to see if it’s readable? Could you have adguard/pihole/etc spoof the target DNS to a local server that then strips the data out of the packets and forwards them on to your homeassistant? Or have they garbled the information with some proprietary nonsense?

If your freezer is on your local wifi and your computer is also on the local wifi you should be able to see all the packets it is transmitting over the wifi with Wireshark on your computer. If either your computer or freezer has a hard connection then you’ll need a little more trickery as switches/home routers minimise network congestion by directing traffic to specific MAC addresses as required.
Assuming you are all wifi, basically you load Wireshark (is free software, easily downloaded) and tell it to capture all packets from your wifi adaptor (there should be a handy option on the initial screen when you load the application). Once you start capturing you’ll be capturing everything on your wifi so it pays to be quick with what you want to achieve to minimise the data.
So, once you start capturing you open your fridge door a few times, leave it open till it beeps, maybe do that twice, then stop capturing. Following that you will just need to filter the capture by all packets from your fridges network IP or MAC (you should be able to find these from your home router). Once you have all the packets you should be able to click on them and expand all the details to see what data they are sending and where it’s being sent to. You should also see all the packets coming back from the vendor.

So long as it’s wifi yeah, everyone can hear everything on wifi when your in range
And so long as it’s not tls encrypted, which i sure hope it is. Afaik the only way to snoop that is to play MITM and forge a certificate or something.

True, won’t be a problem for this use case though

At least it CAN notify. I’ve got a zigbee door sensor glued to the side of the freezer and the door!
My fridge is tilted back a very small amount so the door closes on it’s own.
Replying to @cenzorrll@piefed.ca
This is technology I can get behind. How many tokens does a closure take on average?
Replying to @csolisr@hub.azkware.net
Just connect an ESP32 to the door switch and use that to notify your HA server.
Replying to @csolisr@hub.azkware.net
The ESP32 wouldn’t be able to adjust settings without a lot of hacking, but it wouldn’t be hard to add a temperature sensor so it could monitor that.
Replying to @csolisr@hub.azkware.net
Why would you even buy that? Nothing seems more dumb than a smart fridge.
Replying to @csolisr@hub.azkware.net
I didn’t see that part. But then you hooked it up anyways?

@NewNewAugustEast@lemmy.zip was trying to ask, why did you put it on the network at all, if you have agreed to it being stupid
