Mar 12, 2017 at 17:39 comment added i2r Can anyone please explain me how a capacitor does the trick (make the current bypass the bulb when drawn by the light switch alone)? And what kind/size should it be (maybe some scaling formula)? Is it the only extra component or requires some other resistors (as i've seen somewhere)? Thanks.
Mar 12, 2017 at 17:30 comment added Kevin White Adding a capacitor to every LED/CFL lamp would have the undesirable affect of making the power factor worse for everybody - including those that don't need the feature. It would also reduce the reliability of the lamps, the capacitor would need to be one designed for permanent operation across the supply - I'm sure they cost more than 10c.
Mar 12, 2017 at 17:01 comment added i2r I see a vicious circle, people would buy more smart switches if common light bulbs would work along...

Mar 12, 2017 at 16:56 comment added Trevor_G Yup but users is smart switches is STILL a very small marketplace.
Mar 12, 2017 at 16:54 comment added i2r @Trevor: true enough, but a slightly different product line marketed as "smart switch compatible" that costs some extra 50c/bulb would translate to easy profit. An existing solution is better than none and people expect it to be more expensive. Or might rather the capacitor not be a real solution? I lack the electrical knowledge to answer that... that was part of my dilemma.
Mar 12, 2017 at 16:51 comment added bobflux Yes. Use Bluetooth low energy.
Mar 12, 2017 at 16:41 comment added Trevor_G "I only wonder why didn't the LED/CFL bulbs manufacturers just include this feature in their products" if it costs 10 cents a bulb and they make ten million bulbs a year, that's $1,000,000 not in their pockets.
