If you're a user of Zigbee2MQTT, a key component in home automation, you may have recently encountered a perplexing error message after updating your Home Assistant to version 2023.8. This error, indicating that your “MQTT device name is equal to entity name in your config,” might seem daunting, but there's no need for alarm. Let's dive into what this means and how you can smoothly handle it.


What is Zigbee2MQTT?

Zigbee2MQTT is an open-source software bridge that allows Zigbee devices to communicate with an MQTT server. It acts as a translator between the Zigbee protocol, used by many smart home devices for wireless communication, and MQTT (Message Queuing Telemetry Transport), a popular messaging protocol often used in Internet of Things (IoT) applications. This bridge enables users to integrate various Zigbee-compatible devices, such as sensors, lights, and switches, into home automation systems like Home Assistant, without requiring proprietary gateways. By leveraging Zigbee2MQTT, users can create a more flexible, unified, and cost-effective home automation environment that can be customized to their specific needs.

Is my Zigbee2MQTT and Home Assistant configuration at risk?

Firstly, it's crucial to understand that this error is a minor hiccup in the grand scheme of your home automation system. It's safe to ignore, and the good news is that a forthcoming Zigbee2MQTT update is expected to resolve this issue within the coming month.

The root of the “MQTT device name” error

Your current setup, including all automations and scripts, remains unaffected. They will continue to operate as usual, just as they did in Home Assistant 2023.7. Rest assured, no additional tweaking with names or configuration changes will be necessary when the update is released.

The root of the “MQTT device name equals entity name” error emerged with the release of Home Assistant 2023.8. The primary cause is a naming update for MQTT devices that introduced a has_entity_name property. In layman's terms, Home Assistant began merging the device and entity names to create a user-friendly name. However, this resulted in unnecessarily long and repetitive names, causing confusion and this error message.

Conclusion and further actions

While it's important to stay informed about updates and potential issues, it's equally crucial to approach them with the right information. This error, while seemingly complex, is a minor one and easy to navigate.
