@feld@friedcheese.us @quad@akko.quad.moe every device shares the bandwidth. Doesn't matter that each one only needs a couple tens of b/s on average, when the total channel bandwidth is on the order of a tens of kilobytes, you simply run out after a bunch fo devices. Same with LoRa, and any wireless standard in general. The device count question is largely theorethical, because after a point, the "connected" devices no longer have a useful bandwidth. This get's worse with meshes by the way, each hop essentially uses up double the bandwitdh.

And yeah, farms use LoRa, at 2-3 sensors per acre - that's way less sensors than you'd have at, and at distances where meshing actually starts making sense, because the overlap between wireless ranges of separate devices is low enough that the double transmissions affect a very small portion of devices.And this doesn't even get into the problem of "how does your wired solution allow you to control 3-way dimming light switches while also allowing the physical switch to function too?"THE FUCKING 3-WAY DIMMING SWITCH IS FUCKING WIRED IN TO MAINS, WHY THE FUCK DOES IT NEED TO BE WIRELESS, JUST RUN A FUCKING CABLE TO ITI control the thermostat and ventilation by controller exhaust fans based on indoor and outdoor air quality and temperatures. You want me to run wires everywhere for that? Ridiculous.It's not hard, and if you have that kind of control, you (partially) renovated your home - wiring it up isn't that much harder, it avoids many of the problems, and you most likely HAVE WIRES RUNNING TO ALL OF THESE THINGS ALREADY
