It can happen that you run into trouble while configuring Home Assistant. Perhaps an integration is not showing up or is acting strangely. This page will discuss a few of the most common problems.
Before we dive into common issues, make sure you know where your configuration directory is. Home Assistant will print out the configuration directory it is using when starting up.
Whenever an integration or configuration option results in a warning, it will be stored in
home-assistant.log in the configuration directory. This file is reset on start of Home Assistant.
When an integration does not show up, many different things can be the case. Before you try any of these steps, make sure to look at the
home-assistant.log file and see if there are any errors related to your integration you are trying to set up.
If you have incorrect entries in your configuration files you can use the configuration check command (below) to assist in identifying them.
One of the most common problems with Home Assistant is an invalid
configuration.yaml or other configuration file.
Home Assistant provides a CLI that allows you to see how it interprets them, each installation type has it’s own section in the common-tasks about this:
The configuration files, including
configuration.yamlmust be UTF-8 encoded. If you see error like
'utf-8' codec can't decode byte, edit the offending configuration and re-save it as UTF-8.
To learn more about the quirks of YAML, read YAML IDIOSYNCRASIES by SaltStack (the examples there are specific to SaltStack, but do explain YAML issues well).
configuration.yaml does not allow multiple sections to have the same name. If you want to load multiple platforms for one component, you can append a number or string to the name or nest them using this style:
sensor: - platform: forecast ... - platform: bitcoin ...
Another common problem is that a required configuration setting is missing. If this is the case, the integration will report this to
home-assistant.log. You can have a look at the various integration pages for instructions on how to setup the components.
See the logger integration for instructions on how to define the level of logging you require for specific modules.
If you find any errors or want to expand the documentation, please let us know.
Almost all integrations have external dependencies to communicate with your devices and services. Sometimes Home Assistant is unable to install the necessary dependencies. If this is the case, it should show up in
The first step is trying to restart Home Assistant and see if the problem persists. If it does, look at the log to see what the error is. If you can’t figure it out, please report it so we can investigate what is going on.
It can happen that some integrations either do not work right away or stop working after Home Assistant has been running for a while. If this happens to you, please report it so that we can have a look.
If you are using multiple files for your setup, make sure that the pointers are correct and the format of the files is valid.
light: !include devices/lights.yaml sensor: !include devices/sensors.yaml
lights.yaml (notice it does not contain
- platform: hyperion host: 192.168.1.98 ...
- platform: mqtt name: "Room Humidity" state_topic: "room/humidity" - platform: mqtt name: "Door Motion" state_topic: "door/motion" ...
The only characters valid in entity names are:
- Lowercase letters
If you create an entity with other characters then Home Assistant may not generate an error for that entity. However you will find that attempts to use that entity will generate errors (or possibly fail silently).
