Effortlessly monitor your home's energy consumption with the DIY Smart Powermeter, seamlessly integrated with the user-friendly Home Assistant platform. This powerful project provides real-time data on your household's energy usage and offers the added convenience of a snapshot of your grid's status whenever you open the electric closet, thanks to the 2.9' e-paper display. Featuring an integrated 230VAC to 5VDC regulator, the ESP32-S2 efficiently harnesses power from surrounding wires for optimal performance. The Smart Powermeter supports up to six different CT clamps, with or without a burden resistor, allowing for versatile monitoring options. Additionally, it can measure ambient temperature, giving you comprehensive insights into your energy consumption and surroundings.

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.

Your gateway to a simpler, smarter tomorrow!

Lightweight ESP32-based IoT module for remote data logging enabling the collection and upload of 3D printing statistic values to a cloud server, as well as displaying them locally on a dedicated display. The project also involves extending the Marlin project by adding a custom G-code command at the firmware level.

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.
