v1.99.92

This update adds additional functionality to the Senseair and InfluxDB external components to make them more flexible.

Changes

• Added a manual call for background calibration in Senseair component with senseair_i2c.background_calibration action. This will set current reading at 400ppm. Note there needs to be a power cycle for the calibration to take place.
• Added the senseair_i2c.abc_get_period action to check the current ABC period.
• Improved boot logs for Senseair component to include firmware and serial number
• Reduced CO2 sensor polling from 15s to 30s
• Added the influxdb.publish_sensors action which accepts a list of sensor_ids to publish. Note the id(influx).publish_now() approach still works if wanting to publish all defined sensors.

v1.99.91

Changes

• Use unique filenames for SD card logging. Generated on boot with format mac_yymmdd_hhmm.txt
• Use UTC timestamp for SD card logs
• Fix background calibration for CO2 sensor (180h)

v1.99.90

This update adds a nice feature - SD card support! This is the last piece of base functionality for SAMBA v2 🎉

Changes

• SD cart support using SPI. Measurements are written to SD card at same sample interval as InfluxDB (5 mins).
• some basic remount logic with manual mounting button in HA
• add toggle to disable SD card writing (enabled by default)
• reduced adc sample rates to try and minimise i2c errors
• stagger CO2 reads to try and minimise i2c errors
• reduce i2c timeout setting to 13ms to align with esp-idf limit
• add toggle to disable automatic firmware updates (enabled by default)
• add jitter delay only after confirming there's a firmware update
• reduce sntp syncs to 1 hour

v1.99.80

Changes

• Tested support for new esp-idf i2c stack
• InfluxDB tags are now templatable
• Add configurable read delay to K30
• Increase i2c timeout to 15ms
• More robust RTC setting using actions
• Add placeholder for wifi hotspot network

v1.99.72

Changes

• reduce i2c bus speed to 50kHz
• reduce ADC sample rate to try and minimise issue #19
• reduce sample LED off transition to 300ms

v1.99.71

Changes

• implement managed updates via http_request where update.json hosted in GitHub points to the latest firmware. SAMBAs will check for updates every 6 hours but will only update on Sunday mornings (if an update is available)
• reduced i2c frequency to 50kHz (from 100kHz) to fix occasional crash from bus issues
• hide reset buttons from Home Assistant front end by default

v1.99.70

This is a major release as it switches the default framework to esp-idf from Arduino. This required many changes to the device configuration and custom components

Changes

• default framework is now esp-idf
• refactor of renamed influxdb component to use esp-idf HTTP_client
• improved handling of Influx tagging
• better logging of InfluxDB upload status
• refactor of senseair_i2c component for esp-idf framework
• remove global arrays as workaround for esp-idf bug
• increase TVOC and NOx sampling from 60s to 30s
• rename sensor to tvoc from voc
• simplified sensor names for clearer Home Assistant dashboard
• add transition_length to upload LED
• use SSL for http_requests by default
• explicitly filter NaNs before median filters for all sensors
• explicitly set i2c timeout to 5ms rather than default 13us
• remove redundant diagnostics leftover from beta testing
• testing of managed updates (WIP)

v1.99.66

Changes

• Remove defined network in wifi.yaml to force connection to network saved in flash (from setup)
• Use green strobe effect on warm up

v1.99.65

Changes

• Include wifi signal (wifi) and device uptime (uptime) to Influx uploads
• Add globe temperature back to Influx uploads in case it's needed for diagnostics
• Calculate LAmin (samba_lamin) and LAmax (samba_lamax) and upload to Influx as la_min and la_max measurements
• Change SPL to samba_laeq in ESPHome config and to la_eq in Influx

v1.99.64

Changes

• Properly handle component.update and sensor.template.publish in sample.yaml to fix missing uploads
• Remove Home Assistant upload toggle as it's needed for proper sensor updates
• Remove globe temperature from Influx uploads
• Simplify filters on CO2 and illuminance for debugging
• Add debugging logs to CO2 component
