+- You may need to modify the telegraf configuration to reflect the location of your `vcgencmd`.  Currently, the telegraf configuration is set for

+      commands = ["/usr/bin/vcgencmd measure_temp"]

+  You can check the location of `vcgencmd` on your Raspberry Pi using:
+
+    ```sh
+    which vcgencmd
+    ```
+
+  Typically on Raspberry Pi OS, the `commands` line should be :

 Telegraf configuration requires the following environment variables:
 
 - `INFLUX_HOST` - The URL of your influxdb server.
