A more visual, fancy, and resource-efficient dashboard in Grafana which is an alternative to the pm_dashboard_www application that displays sensor data generated by Pironman - pm_dashboard in influxdb.
Use this Grafana dashboard, especially if pm_dashboard_www is malfunctioning after a while, failing to display sensor data, and giving errors like below or just for fun :-D
pm_dashboard issues/errors:
- Pironman 5 Dashboard empty
- [WARNING] Too many nulls in the result of the query: SELECT * FROM history ORDER BY time DESC LIMIT 20, trying again...
- Request to /api/v1.0/get-data and fails with error 404 Not found
- The server responded with a status of 404 (NOT FOUND) :34001/api/v1.0/get-data
Solution:
- Grafana dashboard to visualize the sensor data recorded at influxdb with more robust and resource efficient way
- Grouping different sensor widgets/panels
- Responsive design for Mobile, Web
- Visualization and Control the application via REST APIs at the same UI
- Auto Refresh by different time intervals like 1s, 5s, 10s, 30s ...
- Sensor widgets for Temperature, Fan, Processor, Memory, Network, Storage
- Alert & Notification definition capability by the thresholds
- Recommended Retention Policy & Wirte/Read optimization for InfluxDB - forum link please apply these instructions
- Simple and easy UI, just shows only the sensor readings
- Everything in Simple Dashboard +
- Advanced and detailed UI design with the variables, buttons and actions
- Control the pironman application settings via REST API
- OLED Control - On/Off, Sleep Timout, Rotation, Disk & Network interface selection
- RGB Led Control - On/Off, Style, Speed, Brightness, Color
- Fan Control - Led On/Off/Follow, Fan Mode
- Logs Panel to show the detailed logs of the selected Log File
Please first change or select the New Option/Configs from the top Variables bar for the specific config and than click the related config's Change button at the below Quick Settings panel.
The "Business Dashboard" is actually enhanced version of the Advanced Dashboard that uses the "Business Variable" plugin to make parameter/variable selections much more user-friendly.
*Unfortunately, the name remained Business Dashboard due to the Business Variable plugin I used, but there is no Business content :-)
- It includes user-friendly components allows for more easier parameter changing on mobile/tablet.
- Slider panel
- Dropdow list panel
- Create Credentials for InfluxDB (Recommended)
Please create a user and password for the influxdb and use this credentials at Grafana influx connection.

- Import the Grafana Dashboard (JSON) files
- Change the "prm_server_url" variable with your raspberry pi server IP address (without http:// or https://) from the Dashboard > Settings > Variables
- prm_server_url : localhost:340001 or ip-address-rpi:34001
- Important: You can have different Storage, Network Interfaces so that you may need to change some of the charts influxdb queries depends on your interfaces.
If you see this error triangle icon inside the panel, please apply the below steps- For example if you don't have the NVME SSD drive than “disk_/dev/nvme0n1_percent” field should not be available or field name should be different like maybe “disk_/dev/nvme1n1_percent” or “disk_/dev/sda_percent” or “disk_/dev/sdb_percent”. In that case please change the field names with yours like below.
- If you see any IP address like this 192.168.1.62:34001 or URL exception please check the prm_server_url variable and change it with your pironman (raspberry pi) server IP address.
