Interesting idea, although the part that got me was the "Zigbee" reference.

IEEE 802.15.4-based specification for personal area mesh networks. "created in 1998, standardized in 2003, ratified in 2004, and revised in 2006." [1] Operates in 2.4 to 2.4835 GHz (worldwide), 902 to 928 MHz (Americas and Australia), and 868 to 868.6 MHz (Europe). Does 10–100m with 250 kbit/sec with focus on low power.

Never heard of this in a quarter century. Not sure if I've ever seen a single reference. Apparently lightbulbs and "person alert" sensors are some of the only real products, and then a lot of hubs.

Zigbee powered the entire IKEA smart home product line for the past several years, until the recent conversion a few weeks ago to to Thread, a generational successor of sorts.


At least in my area of the USA, ZigBee is extensively used by utility meters and other smart grid products.


This is the a behind the scenes description of the following site:

I love this a lot. Bookmarked, watched, and starred, looking forward to updates. Namely, click-on or mouse-over labels for each channel (thinking of a grafana dashboard). I turned everything on and got lost in the spectrum lol.


Any chance of the source code behind this being open sourced?
