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
Default Value: 0
Shift the decimal separator (positiv or negativ).

to liter
(1 m³
equals 1000 liters
), you need to set it to +3
.

This parameter is only supported on the *-class*
and *-const

'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
!

Example: /config/certs/RootCA.pem
.
Warning
This is an Expert Parameter! Only change it if you understand what it does!
Path to the CA certificate file.

Example: /config/certs/client.pem.crt
.
Warning
This is an Expert Parameter! Only change it if you understand what it does!

Usually there is a one pair of Client Certificate/Key for each client that connects to the MQTT broker
Note
If set, ClientKey
must be set too

Usually there is a one pair of Client Certificate/Key for each client that connects to the MQTT broker
Note
If set, ClientCert
must be set too
This also means that you might have to change the protocol and port in uri to mqtts://example.com:8883
!

).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!
Please also make sure that the selected Meter Type matches the dimension of the value provided by the meter!
Eg. if your meter provides m³
, you need to also set it to m³
.
Alternatively you can set the parameter DecimalShift
to 3
so the value is converted to liters
!

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!

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!

Possible values: -100
.. 0
(0
= disabled).
Warning
This is an Expert Parameter! Only change it if you understand what it does!

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: 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!
