Maybe some. On the other hand, the Hue sitting here is cold to the touch when not emitting light and is drawing about 0.4W right now--I checked.
- mordae 5y ago0.4W is a lot. WiFi-connected ESP32 draws about 140 mA. esp8266 will be similar. They are both 3.3V devices. 3.3 * 0.140 = 0.46 Your light bulb's esp8266 (or a similar chip, zigbee is 2.4 GHz as well) is fully powered. With a switching power supply and proper light sleep you should see about 1/10 of that.

- eropple 5y agoHuh--I was certain it could be better, though I didn't realize it was that high! On the other hand, my electricity is hydro and it costs like $0.009 per kilowatt-hour.
