So this started because we recently moved from a flat to a new house and as a visual person, I wanted to see the signal in the new environment (also to check where do I need mesh device). I looked at the existing tools and they're either a few hundred bucks or Windows/Mac desktop apps that want you to install a bunch of stuff, felt like overkill. So I built my own. You upload a floor plan (or just sketch the walls, takes a minute, doesnt have to be that precise), walk around, click where you're standing and type in the signal. It slowly turns into a heatmap and you can see where it goes bad. There's also a "predicted" mode where you drag the router around and it guesses what coverage would look like based on walls before you actually move anything. No account, nothing gets uploaded, it all stays in your browser. Works on a phone too, it's just a bit more fiddly to read the signal there. If you want to see what it looks like without doing anything: https://wifiheatmapper.com/#/app/sample The basic stuff is free and will stay free. I also made a paid version ($79 once, no subscription) mostly aimed at people who do this for clients. It has a small helper app that reads the signal live while you walk, so you don't have to type numbers, plus PDF reports and some other features. Right now everything is unlocked for everyone until end of November anyway, so just try whatever. What I'd really like to know: when you open it for the first time, is it obvious what to do? That's the part I'm still not sure about it. https://wifiheatmapper.com   submitted by   /u/Vojtikk [link]   [comments]
