    Close but not the same…

    Don’t be fooled in to thinking this is the same as the atom lite - it’s not. Great upgrade btw wholly Differnetly code base required when flashing!

    Saved my marriage

    My wife and I had a new baby. She always complains that I either come into the baby's room either too early, or too late, when she's been holding on to our crying baby, trying to calm him down for a long time. This button basically saved my butt because, this button now sits in the baby's room now, and whenever my wife needs me, all she has to do is to press the button with her big toe, and the button them submits a REST API call that triggers a WhatsApp message to be sent to my phone, to let me know that wifey is tired of dealing with the baby and wants to switch out with me. I was even able to stand up a simple webserver that I can access to trigger the LED on the button to blink, as a way for me to quietly communicate with her to see if she wants any help.... And I may have added in an additional hidden feature on the button, via a triple-click, that automatically submits a pizza delivery request to my local Domino's Pizza... That last little feature I added saved me a few times on nights when the wife is out and it's just the baby and I alone.
