I recently learned about LocalSend and was intrigued by how it functioned by only using the WiFi network of the devices. I did not know my LAN had these capabilities.
Now that I’ve learned about it, I am excited to know if there is anything else I can do with it. Perhaps there could be a way to send prank notifications to all the connected devices, create a private chat room, or have custom LAN parties.
I genuinely do not know anything about how WiFi or LAN in general works in this matter. Is it possible for me to build my own applications that make use of these features? If so, I would love to get a direction on what resources or guides I should be looking for. If not, I would still be happy to use similar pre-built applications.
I also use my guest network for the (notoriously insecure) IoT stuff. Oftentimes I’ll take it a step further and use my PiHole to block whatever servers they’re phoning home to.
A good example is my smart TVs. My TVs are the single most blocked devices on my network, by far. Like on a day of heavy use, my phone or PC may generate ~2000 blocked requests. On an average day, my TVs generate 7000+ blocked requests. That’s ~5 attempts to send telemetry data back to the mothership per minute, even when they’re not in use.
