pioreactor-precision-temperature-plugin 0.2.0

Precision temperature automation for Pioreactor using FIR + MLX90632

Pioreactor Precision Temperature Plugin

Installable Pioreactor plugin providing FIR-based liquid temperature estimation and thermostat automation using:

• MLX90632 object temperature
• MLX90632 ambient temperature
• heating PCB temperature

It also includes a one-point bias-trim calibration flow and seeds a default estimator YAML on install.

Install from source

pio plugins install pioreactor_precision_temperature_plugin --source /path/to/pioreactor-precision-temperature-plugin

Post-install behavior

The plugin post_install.sh script will:

1. Copy fir_temperature_estimator_linear_mlx_ambient_pcb_v1.yaml into: $DOT_PIOREACTOR/storage/estimators/temperature_fir/
2. Set it active using: pio estimators set-active --device temperature_fir --name fir_temperature_estimator_linear_mlx_ambient_pcb_v1

If DOT_PIOREACTOR is not set, it defaults to $HOME/.pioreactor.
