  • Other benefit of zigbee that devices can’t connect directly to the internet, so you don’t have to trust them, you don’t have to create vlans, they can’t be turned into a botnet. Also in zigbee every device can be a router, so they can more easily cover bigger houses.

    I wouldn’t replace a wifi based system with zigbee, but recommend it to anyone starting now. This post wanted to be an advice to newcomers…


  • Ikea bulbs use zigbee, their prices are very good and they are more reliable than chinese stuff.

    It’s up to you how you automate your smart home. My useful light related automations:

    • When I arrive home and the light sensor see it’s dark it switches on the living room light
    • if I pause a movie in jellyfin it turns on a light, if I hit play it switches it off
    • The off timer of a movement activated light depends on if my projector is turned on, it switches off more quickly when the projector is on
    • If I’m not home it switches off everything automatically, so I can’t forget any lights on

  • I have an old wifi yeelight, measured it now because I was interested. 1.4W off, 8.4W full power

    For comparison, Ikea zigbee bulb 9.3W max power, less than 0.1 W while off, but switches on instantly. My watt meter can’t measure less than 0.1W so it shows 0.0W.

    Zigbee was designed for this kind of usage. I have several zigbee sensors running on 3.3V coin cell batteries, they can report data for years without battery replacement.


  • These are terrible advices.

    All smart lightbulbs have a small router in them, so they all use some electricity while switched off. You can gain some net plus only if you live with people who constantly forget to switch off lights. But you need some presence detector as well. Smart lighting is about convenience not energy usage.

    Wifi is the worst wireless standard from energy usage standpoint. Zigbee’s power usage is much less and devices are cheap. Thread and Z-wave power usage also lower than wifi, but devices are a bit more expensive.

    Amazon and Google are a privacy nightmare. Home Assistant and Domoticz are two wellknown local first smart home systems.

    It’s in a lot of program, not just ff. You can also see some letters are underlined in that menu, if you press that letter after alt, it would invoke that command or open that drop down without using the mouse. This is a convention at least from DOS, but I suspect it may be even older.

    So actually alt doesn’t unhide the menu, it waits for a letter input to what command you want to start. It just happened that this old type of menu is hidden by default in a lot of programs and alt could be reused for this as well.





  • It’s a marketing article with nearly zero actual facts. One screenshot about the actual product.

    MS and others already use AI for drawing building countours for OpenStreetMap and OvertureMaps from aerial imagery. In osm these AI generated lines are only allowed to be imported after a human supervision and currently it’s very hit or miss. On low density areas it’s mostly good, but in dense city centers it’s unusable.

    In overture maps these lines are imported automatically, that’s why you can see buildings on rivers.

    They don’t write about these shortcomings in the article, and how they solved AI hallucinations
