HomeKit

img HomeKit, also known as Apple Home, is a software framework and communication protocol developed by Apple Inc. that lets users configure, communicate with and control smart-home appliances using Apple devices. It provides users with a way to automatically discover such devices and configure them. By designing rooms, items and actions in HomeKit, users can enable automations in the home through a voice command to Siri or through the Home app. With HomeKit, developers are able to create complex applications in order to manage accessories at a high level.

There isn't a builtin way to record/log sensor data like temperature and humidity. But it does log security activity history like locks and doors opening, etc. And the icloud video camera recording records history.
