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:
- Copy
fir_temperature_estimator_linear_mlx_ambient_pcb_v1.yamlinto:$DOT_PIOREACTOR/storage/estimators/temperature_fir/ - 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.
