1.5.4 Parameter <NUMBERS>.AllowNegativeRates

Default Value: false

Allow a meter to count backwards (decreasing values).

Note

This is unusual (it means there is a negative rate) and not wanted in most cases!


1.5.5 Parameter <NUMBER>.AnalogDigitalTransitionStart

Default Value: 9.2

This can be used if you have wrong values, but the recognition of the individual ROIs are 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. See here for details.

Range: 6.0 .. 9.9.


1.5.6 Parameter <NUMBER>.DecimalShift

Leading N's will be deleted before further processing. This is only relevant for models which use N! See here for details.


1.5.9 Parameter <NUMBER>.MaxRateType

Default Value: AbsoluteChange

Defines if the Change Rate is calculated as the difference between the last two readings (AbsoluteChange = difference) or as the difference normalized to the interval (RateChange = difference per minute).


1.5.10 Parameter <NUMBER>.MaxRateValue

Default Value: 0,05

Maximum allowed change between two readings, if exceeded the last reading will be rejected. Depending on the settings of <NUMBER>.MaxRateType the MaxRateValue is either treated as the difference between the two measurements (AbsoluteChange = difference) not taking the set time interval into account or as the difference normalized to the interval (RateChange = difference per minute).

If negative rate is disallowed and no maximum rate value is set, one false high reading will lead to a period of missing measurements until the measurement reaches the previous false high reading. E.g. if the counter is at 600,00 and it's read incorrectly as610,00, all measurements will be skipped until the counter reaches 610,00. Setting the MaxRateValue to 0,05 leads to a rejection of all readings with a difference > 0,05, in this case 610,00. The rejection also applies to correct readings with a difference > 0,05!


1.5.11 Parameter PreValueAgeStartup

Default Value: 720

  • RESULT_TOPIC: Automatically filled with the right name, eg. value, rate, timestamp, error, ....

The general connection status can be found in MAINTOPIC/CONNECTION. See MQTT Result Topics for a full list of topics.

Note

The main topic is allowed to contain / which can be used to split it into multiple levels, eg. /basement/meters/watermeter/1/ if you have multiple water meters in your basement.


1.6.7 Parameter MeterType

Default Value: other

Select the Meter Type so the sensors have the right units in Homeassistant.

Note

For Watermeter you need to have Homeassistant 2022.11 or newer!

Default Value: true

Warning

This is an Expert Parameter! Only change it if you understand what it does!

Automatically start the Flow (Digitization Rounds) immediately after power up.

Note

Number of days to keep the data files (0 = forever).


1.11.2 Parameter DataLogActive

Default Value: true Activate data logging to the SD-Card.

The files will be stored in /log/data/data_YYYY-MM-DD.csv. See Data Logging for details.

Warning

A SD-Card has limited write cycles. Since the device does not do Wear Leveling, this can wear out your SD-Card!

Default Value: 1 (ERROR) Define the log level for the logging to the SD-Card.

Available options:

  • 1: ERROR
  • 2: WARNING
  • 3: INFO
  • 4: DEBUG

As higher the level, as more log messages get written to the SD-Card.

Warning

DEBUG or INFO might damage the SD-Card if enabled long term due to excessive writes to the SD-Card! A SD-Card has limited write cycles. Since the device does not do Wear Leveling, this can wear out your SD-Card!

Number of days to keep the log files (0 = forever).


1.13 Section System

1.13.1 Parameter CPUFrequency

Possible values:

  • 160
  • 240

1.13.2 Parameter Hostname

Default Value: undefined

Warning

This is an Expert Parameter! Only change it if you understand what it does!

Default Value: 0

Possible values: -100 .. 0 (0 = disabled).

Warning

This is an Expert Parameter! Only change it if you understand what it does!

This parameter activates a client triggered AP switching functionality (simplified roaming). If actual RSSI value is lower (more negative) than RSSIThreshold, all WIFI channels will be scanned for configured access point SSID. If an access point is in range which has better RSSI value (less negative) than actual RSSI value + 5 dBm, the device is trying to connect to this access point with the better RSSI value.

Note

The RSSI check only gets initiated at the end of each round to avoid any disturbance of processing.

Note

It gets automatically transferred to /wlan.ini on the SD-Card at next startup.


1.13.4 Parameter SetupMode

Default Value: true

Note

This parameter is not accessible through the Web Interface Configuration Page!

Set this parameter to true to stay in the Setup Mode after the next start of the device.


1.13.5 Parameter TimeServer

Default Value: pool.ntp.org

Warning

This is an Expert Parameter! Only change it if you understand what it does!

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!


1.13.6 Parameter TimeZone

Default Value: CET-1CEST,M3.5.0,M10.5.0/3

Time zone in POSIX syntax (Europe/Berlin = CET-1CEST,M3.5.0,M10.5.0/3 - incl. daylight saving) Check the table on http://<DEVICE IP>/timezones.html to find the settings for your region.
