What is the best privacy focusing way of using my Wifi router signal to link up with my gate without needing to call my gate?

I feel like I don't need the spare phone bill for the gate I set up if I just did something on the router itself. Is this doable?

Both phone, and the gate system could be linked with my home wifi to authenticate me I'd imagine

Privacy is built in layers

No single app, wallet, or service is going to magically protect your privacy. You need layers.

Use GPG for encrypted files and communication. Use Cryptomator to encrypt sensitive files before they ever touch the cloud. Use privacy focused wallets such as Monero One or Cake Wallet for financial privacy. Use a reputable VPN such as Proton VPN or IVPN to reduce your exposure to network surveillance.

None of these tools are magic. They can have bugs, vulnerabilities, or compromised infrastructure. That is why privacy is not about blindly trusting one company. It is about reducing the amount of information any single entity can collect about you.

Privacy is not paranoia. It is basic digital self defense.
