Thanks for this, fixed my problem by comparing configs.
My ESP config was missing device_class and state_class.
I changed the measurement unit from M3 to m³ also, although I don’t think that was part of the problem.
After changing measurement unit, don’t forget to ‘Fix’ statistics too as described here above.
Dont understand how to set this up
i have a flow sensor which gives me the current flow rate, not accumlating usage.
do i need to put it through utility meter first to get it to count ? and then set it up for energy dashboard?
Hi,
if you only have a flow-rate you first must calculate the absolute value. If you have the flow every 5 minutes, you must add every 5 minutes your value to a counter. You need a always increasing value.
I also tried for hours to add the water consumption to the energy dashboard.
Finally a template sensor works.
Here is the configuration:
sensor water_meter_total_m3:
platform: template
sensors:
water_meter_total_m3:
device_class: water
unit_of_measurement: m³
value_template: "{{ ((states('sensor.n_ergie_watermeter_m3') | float)) | round(2) }}"
attribute_templates:
state_class: total_increasing
This is the configuration of the MQTT Sensor:`
- name: "n_ergie_watermeter_m3"
state_topic: "kg/wasser/main/value"
device_class: water
unit_of_measurement: "m³"
state_class: total_increasing
value_template: '{{value | round(2) }}'
icon: "mdi:water"
In the dashboard I only see the template-Sensor.
I am currently trying to build a water sensor to display it in the dashboard. I get the following information from my water system:
How exactly do I have to set up the sensors so that I can use them?
I currently have these 3rd sensors
...
- name: "bwt_water_consumption_yesterday"
value_template: "{{ value_json.totalWaterConsumption | float(default=0) }}"
unit_of_measurement: "L"
device_class: water
state_class: measurement
icon: mdi:water
- name: "bwt_water_treated_total"
value_template: "{{ value_json.waterTreatedTotal }}"
unit_of_measurement: "L"
device_class: water
state_class: total_increasing
icon: "mdi:water"
...
- name: "bwt_water_treated_total_m3"
unit_of_measurement: "m³"
state: "{{ ( states('sensor.bwt_water_treated_total') | float / 1000 ) | round(3) }}"
icon: "mdi:water"
device_class: water
state_class: total_increasing
Danke, sieht so ähnlich aus, was ich aktuell versuche
template:
sensor:
- name: "Watermeter Value from JSON"
unique_id: water_meter_value_from_json
state: >-
{{ state_attr('sensor.watermeter_json','main')['value'] | float }}
unit_of_measurement: 'm³'
device_class: water
state_class: total_increasing
icon: mdi:gauge
Jedoch werden bei mir leider keine Werte angezeigt, egal welchen sensor ich nehme.
Ich habe an meinem Wasserzähler ein “KY-033 Linien Folger Line Tracking Sensor Modul TCRT5000”, das ich über den Analogport an einem ESP8266 angeschlossen ist, der in ESPHome eingebunden ist. Mit den Digitalen Ausgang habe ich an manchen Stellungen des Liter-Zeigers falsche Impulse bekommen, wenn der Zeiger an bestimmten Stellen stehenblieb.
Mit dem analogen Auslesen gibt es kein Problem mehr. Ich habe den A0 Port direkt mit dem Kollektor des IR-Transistors verbunden. Die Schwellwerte habe ich so gesetzt, dass genügend Hysterese zwischen ON und OFF ist.
Für das Energie-Dashboard habe ich einen Template-Sensor angelegt, dieser muss die Einheit m³ haben.
ESPHome:

Alterntiv, hoffe das passt so:
template:
- sensor:
- name: water_meter_total_m3
unit_of_measurement: m³
value_template: "{{ ((states('sensor.energy_water_m3_total') | float)) | round(3) }}"
device_class: water
attribute_templates:
state_class: total_increasing
How do you read out your sensus 620?
Recently I came across the same problem: all three config params are correct but no sensor in Energy dashboard settings. It appeared that another one precondition must have been met - the sensor’s data must be recorded to DB, and this is not quite obvious. I have custom settings for recorder, not to overload the DB with hundreds unneeded sensors, so after I manually added my water meters sensors to recorder config and restarted HASS - all works.
