From the fine article itself:

> If you wanted to have this thing completely isolated though, you could have a no-outbound-internet subnet with this device on it so long as the device you are going to run the script on has line-of-sight.

> You can do this because Tuya devices have a local-only protocol that tinytuya supports, so you can send commands just within your LAN.

I read the article. The bit you quote talks about putting the device in a firewalled subnet, because it is not a local-only device: it will try to dial out to a third party server, so it must be placed in a subnet which will block those attempts.

I want a device which I can put on my network and which will not try to dial out to the world. This device is not that.
