Incorrect And Missing Entity Attributes In Home Assistant

by ADMIN 58 views

Introduction

Home Assistant (HA) is a popular open-source home automation platform that allows users to control and monitor various devices and sensors in their homes. However, with the latest versions of HA, users have reported issues with missing and incorrect attributes on most entities. In this article, we will explore the problem of incorrect and missing entity attributes in Home Assistant and provide solutions to fix these issues.

The Problem

The problem of incorrect and missing entity attributes in Home Assistant has been reported by several users. Earlier versions of HA allowed users to correct and add attributes in the configuration.yaml file. However, with the latest versions of HA, this is no longer possible. At least, not for correcting an incorrect attribute.

To illustrate this problem, let's take the example of a user who is using the Nibe EB100-BE3 current sensor. The user is no longer receiving current sensor data with HA 2025.3.1. The HA log shows the following error message:

### Error Message

Logger: homeassistant.components.mqtt.entity
Source: components/mqtt/entity.py:155
integration: MQTT (documentation, issues)
First occurred: 12:37:53 (3 occurrences)
Last logged: 12:37:54

Error 'The unit of measurement `A` is not valid together with device class `power`' when processing MQTT discovery message topic: 'homeassistant/sensor/40081/config', message: '{'device_class': 'power', 'unit_of_measurement': 'A', 'state_topic': 'nibe/modbus/40081', 'name': 'Nibe EB100-BE2 Current'}'
Error 'The unit of measurement `A` is not valid together with device class `power`' when processing MQTT discovery message topic: 'homeassistant/sensor/40083/config', message: '{'device_class': 'power', 'unit_of_measurement': 'A', 'state_topic': 'nibe/modbus/40083', 'name': 'Nibe EB100-BE1 Current'}'
Error 'The unit of measurement `A` is not valid together with device class `power`' when processing MQTT discovery message topic: 'homeassistant/sensor/40079/config', message: '{'device_class': 'power', 'unit_of_measurement': 'A', 'state_topic': 'nibe/modbus/40079', 'name': 'Nibe EB100-BE3 Current'}'

The Cause of the Problem

The cause of the problem is a bug in the Nibe PI index.js file. Specifically, lines 1260-1261 in the file are causing the issue:

### Bug in Nibe PI index.js

1260-        } else if(result.unit=="A") {
1261:            result.type = "power";

This code is setting the type attribute to power when the unit attribute is A. However, this is incorrect because the unit attribute A should be associated with the current device class, not the power device class.

The Solution

To fix this issue, the user needs to correct the type attribute in the configuration.yaml file. However, as mentioned earlier, this is no longer possible with the latest versions of HA.

Instead, the user can try to correct the issue by modifying the Nibe PI index.js file. Specifically, the user needs to change lines 1260-1261 to:

### Corrected Code in Nibe PI index.js

1260-        } else if(result.unit=="A") {
1261:            result.type = "current";

This will set the type attribute to current when the unit attribute is A, which is the correct association.

Conclusion

In conclusion, the problem of incorrect and missing entity attributes in Home Assistant is a complex issue that requires a deep understanding of the HA platform and its components. While the latest versions of HA have made it more difficult to correct and add attributes, there are still ways to fix these issues. By modifying the Nibe PI index.js file, users can correct the issue and ensure that their entities are working correctly.
