Homekit Bridge Air Purifier Incorrect Temperature
Introduction
Home Assistant, a popular open-source home automation platform, has recently introduced support for air purifiers in HomeKit Bridge. However, some users have reported an issue with the temperature sensor associated with their air purifier, displaying incorrect readings. In this article, we will delve into the problem, identify the affected version of Home Assistant Core, and explore possible solutions to resolve the issue.
The Problem
The issue was first encountered with the latest version of Home Assistant (2025.5.0), which introduced support for air purifiers in HomeKit Bridge. The air purifier is successfully detected in HomeKit, but its associated temperature sensor is displaying an incorrect reading of 163°C. This is believed to be a conversion issue from Fahrenheit to Celsius.
Identifying the Affected Version
The issue is specifically related to the core-2025.5.0 version of Home Assistant Core. This version was released with the support for air purifiers in HomeKit Bridge, but it appears to have introduced a bug that affects the temperature sensor readings.
Last Working Version
The last working version of Home Assistant Core that did not exhibit this issue is core-2025.4.4. This version was released before the introduction of air purifier support in HomeKit Bridge and did not have the conversion issue.
Installation Type
The issue is being experienced on a Home Assistant OS installation. This is a pre-configured operating system designed specifically for Home Assistant, making it easier to set up and manage home automation systems.
Integration Causing the Issue
The HomeKit integration is the cause of the issue. This integration allows Home Assistant to communicate with HomeKit-enabled devices, including air purifiers. However, it appears that the conversion from Fahrenheit to Celsius is not being handled correctly, resulting in incorrect temperature readings.
