Special version of ESPbutton, oprimized for size and current consumption. It can be powered by one CR2032 battery for 1 year at 1 push/hour or 2xAAA batteries for 5 years at 1 push/hour or 1 1/2 years at 10 pushes per hour. It is designed to send toggle commands through ESP-Now to a MQTT server to control anything that you connect it to through Node Red, for example lights, blinds, etc.
- encrypted ESP-Now connection
- 2 touch buttons (up/down or left/right depending on how you position the unit).
- due to requiring the smallest power consumption possible, the setup is done by flashing the firmware, there is no webpage or phone setup on this model
Roll your own or get one from 3DStar shop in PCB, kit (PCB + components) or fully assembled form.
The ESP-12S from AI Thinker is used to send the state of the 2 touch sensors. You can assign lights, shutters/blinds, doors/gates, irrigation or any other action that you wish. The number of boards you can use is unlimited. The trick here is that when using ESP-Now, all button boards share the same MAC address.
