Q: Am I totally of the grid now? (HTTP connection)

[Simension]

Hi guys,
I installed a MSS210 smartplug with the help of the official Meross app, so the device is immediately detected in HA afterwards. Then in HA I used my account-credentials to fetch my devicekey and to connect the smartplug to HA.
I deleted the same Smartplug from HA, reinstalled it not using my credentials but only the device-key.
I even deleted the smartplug out of the official Meross app and the internet-connection is blocked for the plug in router-settings. In HA I configured it to only http. Its working perfectly fine and is only appearing in HA.
Is the Meross-Server now used in any way or am I totally off the grid and using it only local? In the docs its said "The integration will just 'side-communicate' over HTTP". So "side-communicate" means only local?
Sorry if I get anything wrong. Iam new to HA and to smarthomestuff. I just want to use it without any external servers which could track me.
Thank you guys!

P.S: I found this thread which seems to answer my question (#322). But perhaps the slightly different way I did it and the following discussion could be also a help for others who want a easy way to go local. So I will start this thread anyway if this is okay for you guys (please tell me if this is not okay, i will delete then).

Hello @Simension,
As for the device, having blocked any internet-bound traffic it is only locally available (if we trust the router;).
As for meross_lan, you just have to disable/delete any 'Meross cloud profile' entry so that meross_lan will not attempt any outbound traffic which would anyway be useless since the device, being firewalled, doesn't have cloud-mqtt connectivity.

Fixing protocol to HTTP for the device configuration is the last step, just a refinement, but this step, by itself, would not prevent meross_lan to connect to the cloud mqtt broker since this connection is established when you setup the aforementioned 'Meross cloud profile' regardless of any device configuration

Thanks for further information krahabb! (And thanks for integration, works perfectly fine! Its a pleasure!) Oright, deleted the Meross cloud profile already which was also visible under the hubs segment.
By the way for all guys who have a local dns-resolver like pihole: Even if internet-connection is blocked for the smartplug it will send dns-queries like "mqtt-eu-4.meross.com" to pihole because it is local. They will be answered.
