I visualise my Solar Thermal and boiler input to my water cylinder with the following graph.
In 2023.4 it looks like this, item 1 in the image
But in 2023.5/6 I get this, item 2 in the image
Everything else is the same, same graph, same template, same inputs and the same version of Apex charts (latest v2.0.4).
The only symptom I can see is that in the history it now appears to now save the last state.
See item 4 in the image
Where in 2023.4 it doesn’t.

This has been in and running since Q3 2022. I do think it took me a few attempts to get it right, as I had tried using unavailable and null in my sensor, but none of them worked. So the configuration I ended up using is;
#Solar pump
- sensor:
- name: sensor.solar_pump_set_temperature
unique_id: sensor.solar_pump_set_temperature
state: >
{% if states('sensor.pump_speed_relay_1')|float(0) > 10.0 %}
{{states('sensor.temperature_sensor_2')}}
{% endif %}
unit_of_measurement: "°C"
state_class: measurement
I have checked the release notes and can see no mention of this being affected by any changes. I tried putting in an ‘else’ so it was a complete if statement, but that also hasn’t worked.
So have I coded it wrong, or is it no longer the right way?
