## Config.ini:

Expert Mode

Enable | Parameter | Value | Information
--- | --- | --- | ---

#### MakeImage

| LogImageLocation |  | Location to store raw images for logging
<td"> | LogfileRetentionInDays |  | Time to keep the raw image (in days -"0" = forever)
| WaitBeforeTakingPicture |  | Wait time between illumination switch on and take the picture (in seconds)
| ImageQuality |  | Quality index for picture (default = "5" - "0" high ... "63" low)
| ImageSize |  | Picture size camera (default = "VGA")
| Brightness |  | Image Brightness (-2 .. 2 - default = "0")
| FixedExposure |  | Fixes the illumination setting of camera at the startup and uses this later --> individual round is faster

#### Alignment

| SearchFieldY |  | y size (height) in which the reference is searched (default = "20")
| AlignmentAlgo |  | "Default" = use only R-Channel, "HighAccurity" = use all Channels (RGB, 3x slower), "Fast" (First time RGB, then only check if image is shifted)

#### Digits

| Model |  | Path to CNN model file for image recognition
| LogImageLocation |  | Location to store separated digits for logging
<td"> | LogfileRetentionInDays |  | Time to keep the separated digit images (in days -"0" = forever)

#### Analog

| Model |  | Path to CNN model file for image recognition

#### PostProcessing

| PreValueUse |  | Enable to use the previous read value for consistency checks - also on reboots
| PreValueAgeStartup |  | Time (in minutes), how long a previous read value is valid after reboot (default = 720 min)
| AllowNegativeRates |  | Set on "false" to ensure, that only positive changes are accepted (typically for counter)
| ErrorMessage |  | Do not show error message in return value - in error case, the last valid number will be send out
| CheckDigitIncreaseConsistency |  | Enable additional consistency check - especially zero crossing check between digits
Postprocessing Individual Paramters:
| DecimalShift |  | Shift the digit separator within the digital digits (positiv and negativ)
| MaxRateValue |  | Maximum change of reading per minute
| ExtendedResolution |  | Enable to use the after point resolution for the last analog counter
| IgnoreLeadingNaN |  | Leading "N"'s will be deleted before further processing

#### MQTT

| Uri |  | URI to the MQTT broker including port e.g.: mqtt://IP-Address:Port
| MainTopic |  | MQTT main topic, under which the counters are published. The single value will be published with the following key: MAINTOPIC/VALUE_NAME/PARAMETER where parameters are: value, rate, timestamp, error The general connection status can be found in MAINTOPIC/CONNECTION
| ClientID |  | ClientID to connect to the MQTT broker
| user |  | User for MQTT authentication
| password |  | Password for MQTT authentication

#### AutoTimer

| AutoStart |  | Start the image recognition immediatly after power up. false is basically for debugging.
| Intervall |  | Intervall in which the counter is read (in minutes). Number must be greater than 3 minutes.
