I have installed an esp temperture probe next to mine pool pump.
I want a display, that shows the pool temperature only when the pump is running.
it would only be nice to show the last know temperature when the pump has run.
for the moment i have this set up:
- name: "zwembadwater temperatuur filtered"
unique_id: zwembadtemp_filtered
icon: "mdi:coolant-temperature"
unit_of_measurement: "°C"
device_class: temperature
state_class: measurement
state: >
{% if is_state('light.pomp_verwarming', 'on') %}
{{ states('sensor.zwembadwater_temperatuur') }}
{% else %}
Nb
{% endif %}
Why?
because the temperature at the pump is not the correct value of the pool, pipes warm/cool down quickly)
