| Parameter | Value | Information |
|---|---|---|
TakeImage |
||
| Location to store raw images for logging | ||
| Time to keep the raw image (in days, resp. "0" = forever) | ||
|
|
Wait time between illumination switch on and take the picture (in seconds) | |
|
|
Quality index for picture (default = "12" - "0" high ... "63" low) Remark: values smaller than 12 can result in a reboot, as the bigger sized JPEG might not fit in the available RAM! |
|
|
|
Picture size camera (default = "VGA") | |
|
|
Internal LED Flash Intensity (PWM from 0% - 100%). Remark: as the camera autoillumination settings are used, this is rather for energy saving, than reducing reflections. |
|
|
|
Image Brightness (-2 .. 2 - default = "0") | |
|
|
Image Contrast (-2 .. 2 - default = "0") Remark: camera driver is not fully supporting this setting yet (no impact on image) |
|
|
|
Image Saturation (-2 .. 2 - default = "0") Remark: camera driver is not fully supporting this setting yet (no impact on image) |
|
|
|
Fixes the illumination setting of camera at the startup and uses this later --> individual round is faster | |
Alignment |
||
|
|
x size (width) in which the reference is searched (default = "20") | |
|
|
y size (height) in which the reference is searched (default = "20") | |
|
"Default" = use only R-Channel, "HighAccuracy" = use all Channels (RGB, 3x slower), "Fast" (First time RGB, then only check if image is shifted) |

|
Path to CNN model file for image recognition. Check the documentation for details. | |

PostProcessing |
||
| Enable to use the previous read value for consistency checks - also on reboots | ||
| Time (in minutes), how long a previous read value is valid after reboot (default = 720 min) | ||
| Set on "false" to ensure, that only positive changes are accepted (typically for counter) | ||
| Do not show error message in return value - in error case, the last valid number will be send out | ||
| Enable additional consistency check - especially zero crossing check between digits | ||
|
Postprocessing Individual Parameters: |
||
| Shift the digit separator within the digital digits (positiv and negativ) | ||
| If you have false Values, but the recognition is correct. Look for the start of changing of the first digit and note the analog pointer value behind. Set it here. Only used on combination of digits and analog pointers. Default=9.2 | ||
| Maximum change of a reading - if threated as absolute or relative change see next parameter. | ||
| Defines if the change rate compared to the previous value is calculated as absolute change (AbsoluteChange) or as rate normalized to the interval (RateChange = change/minute). | ||
| Enable to use the after point resolution for the last analog counter | ||
| Leading "N"'s will be deleted before further processing | ||
|
|
||
| URI to the MQTT broker including port e.g.: mqtt://IP-Address:Port | ||
|
MQTT main topic, under which the counters are published. The single value will be published with the following key: MAINTOPIC/VALUE_NAME/PARAMETER where
|
||
| ClientID to connect to the MQTT broker | ||
| User for MQTT authentication | ||
| Password for MQTT authentication | ||
| Enable or disable the retain flag for all MQTT entries | ||
Homeassistant Discovery (using MQTT)The discovery topics and the static topics (IP, MAC, Hostname, Interval, ...) only get sent on startup. To send them again, you can call the following URL: http://<IP>/mqtt_publish_discovery |
||
| Enable or disable the Homeassistant Discovery | ||
|
Select the meter type so the sensors have the right units in Homeassistant. Note: For 'Watermeter' you need to have Homeassistant 2022.11 or never! |
||
Only InfluxDB v1.x is supported, v2.x has a changed interface |
||
| URI of the HTTP interface to InfluxDB, without traililing slash, e.g. http://IP-Address:Port | ||
| Database name in which to publish the read value. | ||
| Measurement name to use to publish the read value. | ||
| User for InfluxDB authentication | ||
| Password for InfluxDB authentication | ||

AutoTimer |
||
|
|
Start the image recognition immediatly after power up. false is basically for debugging. | |
|
|
Interval in which the number(s) are read (in minutes). If a digitalization round takes longer than this interval, the next run gets postponed until the current run completes. | |
DataLogging |
||
|
|
Activate data log to SD card | |
|
|
Time to keep the data files (in days - "0" = forever) | |
Debug |
||
|
|
Set the level of the logging to the SD-Card. Warning: DEBUG or INFO might damage the SD-Card if enabled longterm due to excessive writes to the SD-Card! |
|

System |
||
|
Time zone in POSIX syntax (Europe/Berlin = "CET-1CEST,M3.5.0,M10.5.0/3" - incl. daylight saving) Use this table to find the settings for your region. |
||
|
Time server to synchronize system time. If it is disabled or "undefined", "pool.ntp.org" will be used. You can also set it to the IP of your router. Many routers like Fritzboxes can act as a local NTP server. To disable NTP, you need to activate it but set the TimeServer config to be empty. In such case the time always starts at 01.01.1970 after each power cycle! |

| Hostname for server - will be transfered to wlan.ini at next startup) | ||
| WLAN Mesh Parameter: Threashold for RSSI value to check for start switching access point in a mesh system. Possible values: -100 to 0, 0 = disabled - Value will be transfered to wlan.ini at next startup) | ||
