Read this official Leafony page and explain its key points in English. For hardware help, first ask for a photo or the installed leaf models, assembly and power sources, then the goal and tools. Clarify which LED or display changed and whether a cable or leaf was replaced. Do not equate an unseen reset button with an absent one, or I2C acknowledgement with a working display. Verify specifications against sources; distinguish observations from hypotheses. Follow a redirect to its destination; if unreadable, ask for the relevant text instead of guessing.

Description / headings (excerpt): Features / Specification / Dimension / Temperature/Humidity Sensor

Features

Measure temperature, humidity, ambient light (illuminance), and acceleration. Combined with an MCU (microcontroller) leaf, this leaf lets you read changes in the surrounding environment and the leaf’s movement.

It has a temperature/humidity sensor, an illuminance sensor, and an accelerometer. The MCU leaf reads their measurements over I2C.
