ESP8266 Dash Button with AAA Batteries

thingiverse

Well, I'm loving the ESP8266 dash buttons! I had a tool running on a pi to detect when one of them comes up and then my home automation server gets a request and one of my lamps turns on or off. Now the batteries are dead and the ESP8266 buttons don't work anymore. Now... I've got an ESP8266 dash button, and I won't explain here how you'll have to flash firmware, which one is best, and how it works. My code is self-written... Pretty simple. In Setup just do: * Connect to WiFi * Wait until WiFi connection is available * Send HTTP request to my Loxone Home Automation Server * ESP.deepSleep(); Underneath the coiled up copper wire you see in my pictures is a little bit of space so you can put there an ESP-01, an ESP-07 or an ESP-12. Whatever version you want if it has a reset connection. I used some 0.25mm² CCA copper wire and in a second one just CAT 7 Network Cable wires;). It is stiff enough to create some resistance when you put the batteries in this dash button. At the bottom end side are two holes which are both ends of a tunnel:). Push the cable through, give both ends a twist and you have negative of one battery connected to positive of the other battery.
