Your gateway to a simpler, smarter tomorrow!

Hello everyone, makers and robotics enthusiasts! Today I want to talk to you about a component that is capturing my attention and that could revolutionize your next HMI (Human-Machine Interface) projects: it is the CrowPanel ESP32 4.2” E-paper HMI Display produced by Elecrow

Build a Digital Timer Switch that allows you to switch devices on or off on a specified schedule, e.g. your garden sprinkler or lights in your home. This Digital Timer Switch will always have accurate time since it synchronizes its clock with an internet time server. No need to adjust the clock for daylight savings time or to set it after a power outage. Furthermore, the large display makes it easy the set or change schedules.

Weather Crow is an ESP32-S3 based weather station featuring an E-paper display that shows current weather conditions and forecasts. This initial release provides a complete solution for monitoring local weather with minimal power consumption through efficient deep sleep cycles. the project is under the MIT license, so you can modify or chage as you want!!

Never Lose Power Again — Real-Time Energy Monitoring Made Easy

Two simple local projects to introduce you to the basic finctions, and some of the possibilities of this Arduino Kit.

eBUS Adapter Stick C6 is a reduced size version of previous highly demanded eBUS Adapter Shields and provides an interface to a 2-wire eBUS with galvanic isolation for enabling communication with an eBUS enabled heating, ventilation or solar system. With a size of 42 x 16 mm it is way smaller than the previous Shield versions, but still supports an USR-ES1 module being plugged onto it for having Ethernet access. Even better, with the upcoming firmware version for the ESP32-C6, it automatically scans the heating components and makes all data available via MQTT to e.g. Home Assistant with auto discovery of entities.
