Hello,
I recently setup a Development instance of my Home Assistant, where I did a restore from backup. I then disconnected it from Nabu Casa. I have never logged into this instance on my phone, and it is able to send push notifications to my device. I am using the Notify service.
The instances have different IP’s and DNS entries internally/externally for each instance.
This also occurs on just cellular/out-of-band.
How is this possible/how do I stop this from occurring without having to block the Dev instance’s internet?
