+# Troubleshooting plugins
+
+## High-level overview
+
+If a Plugin supplies data to the main app it's doine either vie a SQL query or via a script that updates the `last_result.log` file in the plugin folder (`front/plugins/<plugin>`).
+
+For a more in-depth overview on how plugins work check the [Plugins development docs](https://github.com/jokob-sk/Pi.Alert/blob/main/front/plugins/README.md).
+
+### Prerequisites
+
+- Make sure you read and followed the specific plugin setup instructions.
+- Ensure you have [debug enabled (see More Logging)](https://github.com/jokob-sk/Pi.Alert/blob/main/docs/DEBUG_TIPS.md#1-more-logging-) 
+
+### Potential issues
+
+- Bugs
+- Unexpected input (e.g. special characters in names)
+- Dependencies changed how data is output
+
+#### Incorrect input data
+
+Input data from the plugin might cause mapping issues in specific edge cases. Look for a corresponding section in the `pialert.log` file, for example notice the first line of the execution run of the `PIHOLE` plugin below:
+
+```
