Hi,
I am using an Ultrasonic Sensor for measuring the filling level of my oil tank. To show the amount of oil that could be ordered at any given point, I am simply using a Template-Sensor which calculates Max Fill-level - Current Fill-level, nothing fancy. Up and until 2025.2.1 everything worked. Since the update there is no longer a value being shown. Yesterday I was able to see a value on the graph, but since 6pm yesterday evening no new value had been calculated.
This is the Template-Sensor:
- name: "Ölverbrauch"
unique_id: "oelverbrauch_sensor"
unit_of_measurement: L
device_class: volume
state_class: total
state: >
{{ 2880 - (float(states('sensor.oilfox_on1104361306_filllevelquantity'))) }}
Using the formula in the dev tools, everything still works
Within the dashboard, no new values are shown anymore (“Aktuelle Bestellmenge”):
This has been the data graph until yesterday:
I even added a trigger to the template-sensor, still, nothing being calculated. The ultrasonic sensor sends data once a day, which worked today as well.
I am confused what might be wrong, all of a sudden. Any ideas anyone?
Thanks
Frank
