Hi everyone! I recently upgraded my home lighting to a smart system on a budget and wanted to share the steps:

Choose affordable smart bulbs: Brands like Wyze or Sengled are great budget options. Set up a smart hub (optional): If you’re going for a cohesive ecosystem, consider hubs like Alexa or Google Home. Install and connect: Replace your old bulbs, connect them to your Wi-Fi, and use the corresponding app for setup. Automate: Use routines or schedules for energy-saving and convenience. Let me know if you’ve tried something similar or have any questions!

    1 to 3 Watt in stand-by mode for s lamp that draws somewhere between 7 and 15 Watt when on. That’s roughly like leaving the lamp on for at least on hour and half each day when nobody is home in the best case.

      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.

      That’s a pretty high estimate, this article claims to have measured it at 0.5W/bulb (0.15W for zigbee). That’s still 3x or so higher than Zigbee, but still decent.

      I have about 50 bulbs in my house, so that’s:

      • ~5.4kWh/month for zigbee
      • ~18kWh/month for WiFi

      At $0.15/kWh, that’s $1.89/month savings with zigbee. That’s not nothing, but it’s not something I’d switch out a bunch of bulbs over.

      It may make sense for an airbnb rental property or something, but I don’t see a point for average homes, and I’d expect adding dozens of WiFi clients would cause problems with WiFi quality.

        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…
