ESP-01 IoT WiFi Button

thingiverse

This is a remix of the IoT Button from kaypohl and also of the CR2 Batteryholder from enif. My problem was that I only wanted a http request button to control my shelly-switches, so I'm completely free of any server needed to toggle them. In case of cloud problems or when my openhab dies. I chose the ESP-01 because it was the best and cheapest option for easy OTA flashing. Just get it out of its case again and put it on the programmer without a battery inserted, no need to desolder anything. The memory size is too low for OTA flashing. I also wanted an easy assembly with less welding, and I didn't want to buy any Battery-springs or other stuff. You don't need anything to glue; just put it together as shown in the picture, and everything holds itself inside. If you don't have a small button like me, you need to cut it down a bit. The code simply sends a http request after connecting to your wifi. The ino file is added and also commented - just change your wifi credentials and the URL. An example for shelly devices is included. It needs around 5 seconds to do the task. After the first connection, it switches much faster, but only for a while because of the DeepSleep. When you press the button, it reboots. If you have any questions, just feel free to ask in the comments.
