I noticed since my last HA update, there is constant traffic…
I looked deeper, and it seems it’s SSDP traffic somehow related to the Nabu Casa service. All of these have been active for a long period since the upgrade.
Does anyone have any idea why there is constant data transfer to Nabu Casa? Or am I missing something? I never had this much constant traffic before…
Thanks,

Is your HA a yellow? if so there is data going to Nabu Casa on errors, checking updates, updates installed, what manufacturers are being used, how many devices.
No. It’s just running on a Pi4….
Nuba Casa did acquire ESPHome and some others. You didn’t subscribe to their cloud free trial did you?
No. I just pay Nabu Casa… No ESPHome at all… No new integrations. Seems to coincide with graphs being real time in the next release… Although that might be conspiracy theory… 
So you are subscribed to their cloud service then. They own ESPHome which makes IoT parts/kits to build devices for home automation.
I didn’t know any details about that… I have paying for the Nabu Casa subscription forever. It just never caused this continuous data usage. I’m stumped…
Maybe this is just a change in reporting on my router or something… I logged out of Nabu Casa on my instance and the data stream didn’t stop.
This was definitely Home Assistant. I shut it down, and the transfer stopped. Rebooted and now it’s okay. Something in HA was definitely stuck on transmitting endless data.
Sometimes a reboot fixes a lot of stuff.
