+
+How to collect Raspberry Pi CPU and GPU temperature with Telegraf to later display it in a nice Grafana Dashboard.
+
+## How to use (No script required)
+
+---
+
+#### 1. Add this to you telegraf.conf
+
+```TOML
+[[inputs.file]] 
+  files = ["/sys/class/thermal/thermal_zone0/temp"]
+  name_override = "cpu_temperature"
+  data_format = "value"
+  data_type = "integer"
+  
+[[inputs.exec]]
+  commands = [ "/opt/vc/bin/vcgencmd measure_temp" ]
+  name_override = "gpu_temperature"
+  data_format = "grok"
+  grok_patterns = ["%{NUMBER:value:float}"]
+```
+#### **2.** Add telegraf user to video group 
+For telegraf to be able to get the GPU temp the telegraf user needs to be add to the video group. Do so with the command below:
+```bash
+sudo usermod -a -G video telegraf
+```
+
+#### **3.** Check that the telegraf config file is correct (Recommended)
+Run the test with:
+```bash
+telegraf -config /etc/telegraf/telegraf.conf -test
+```
+
+#### **4.** Restart telegraf service
+Restart telegraf to activate the new settings.
+```bash
+sudo systemctl restart telegraf.service
+```
+
+#### **5.** Check that everything is working
+Double check that everything is working in order
+```bash
+sudo systemctl status telegraf.service
+```
