GE "smart" lightbulb reseter

Cause live is to short for:
Have you tried to switch it off and on again? And again, and again, and again, and again, and again...?

[Radomir]( asked me if I saw this hillarious video on how to reset GE lightbulbs. So let's simplify switching off and on stuff. Because i have some spare microcontroller and relay boards somewhere.


needs some automatic solution.

Look no further, here's some IoT to save you from broken IoT. Just send an SMS with "ge_post_2.8" or "ge_pre_2.7" to reset the connected GE smart bulb.

I heard that other manufacturer made some similar reset procedures, I may add them in the future.


Schematic (only one relay, in the code there are two, since I have a two channel relay breakout, and the code is recycled from another project)

    Just some short notice that I added a simple "on" and "off" SMS command today.

    Was harder than expected because of reduces brain capacity of mine (heatwave, you know), Arduinos capabilty of cryptic error messages and some broken update... but finally it worked.

    Next step: morse "parser" because how awesome would it be to send an SMS to your lamp, which then morses the content of that SMS...

    Setup Arduino

    First setup your Arduino IDE to work with the MKR GSM 1400:

    Make sure you have a SIM at hand that can receive SMS.

    Low voltage stuff

    Connect a relay breakout to pin 7, mine needed to be connected to VCC and GND. And one of the signal inputs to 7.

    Connect some neopixels, I used a 16 neopixel ring, to 3.3V, GND and pin 5. 

    Side note here, neopixel's spec says the difference between power and signal should be 0.7V max. That's why I power them with 3.3V

    High voltage stuff

    Warning, hic sunt dragones.

    This step has the potential to kill somebody, including yourself, if you're not qualified ask an electrician friend.

    Prepare one cable with a wall plug and a second with a lamp socket. Connect them using the relay, according to your local rules.

The crazy part is that this actually seems like a fairly rational solution to the problem...

Well, except the SMS to reset part maybe...

It's a good monetization strategy!
