Pioreactor OLED Status Display Plugin

Show Pioreactor status on a 128x64 monochrome OLED display.

This is a long-running Pioreactor plugin job named oled_status_display. It subscribes to local Pioreactor MQTT topics and renders a compact terminal-style dashboard with:

• unit name and horizontally scrolling IP address
• OD filtered
• growth rate
• temperature
• measured RPM
• transient warning and error banners

The display supports SSD1306 128x64 I2C OLEDs by default. The code can also use adafruit_sh1106 if that driver module is installed separately; by default, the plugin tries SSD1306 first, then SH1106.

Install From Source

pio plugins install oled_status_display --source .

The plugin includes a post_install.sh hook that starts and enables the startup service:

sudo systemctl enable pioreactor_startup_run@oled_status_display.service

It also includes a pre_uninstall.sh hook that stops and disables the same service.

Configuration

The following defaults are installed into Pioreactor configuration:

[oled_status_display.config]
refresh_interval_seconds=2
banner_seconds=5
driver=auto
i2c_address=0x3C
rotation=2
metrics=od_filtered,growth_rate,temperature,measured_rpm

Set driver to ssd1306, sh1106, or auto. Set i2c_address to the detected display address, commonly 0x3C or 0x3D. Set rotation to 0, 1, 2, or 3.

Set metrics to a comma-separated list of exactly four metric ids. These names match the corresponding Pioreactor core MQTT attributes:

• od_filtered
• ods
• od_fused
• growth_rate
• temperature
• target_temperature
• measured_rpm
• target_rpm
• volume_change
• current_volume_ml

Run Manually

pio run oled_status_display
