Monitors humidity sensors.
Usage: humidity_control [options]
-h, --help Display this screen
Configuration:
- (1) file as specified by environment variable HUMIDITY_CONTROL_CONFIG_FILE,
- (2) /data/.config.
Monitors an ESP32 microcontroller which provides humidity data given by an FC37 humidity sensor via a webservice. Respective ESP32 software can be found here:
/Users/ms1/Programmierung/Arduino/esp32_humidity_server/esp32_humidity_server.ino
Needs a YAML configuration file either in /data/.config or as specified by the environment variable HUMIDITY_CONTROL_CONFIG_FILE.
Start the control program in the background, write all output to logfile log.txt:
bin/humidity_control &> log.txt &
Alternatively, using setsid to invoke the control program in the background without being connected to the process hierarchy, which is useful when being invoked from an ssh session:
setsid bin/humidity_control &> log.txt
Following points need to be taken care of:
- If sensor is up after being not available, sent status update
- Update config: Time to send status SMS
- Handle multiple sensors
- Rescue IOError and redo while alerting
- Overwrite LOGGER.warn with @@warnings += 1?
