Hi
i have a number of temperature sensors around my house all connected to esp32 boards
i would like to have 2 entities that track all time max and min temps,
I can see this data on the history graph, showiung the sensor data and the long term statistics
Ive created 2 helpers which only showed recent data min/max, so i i've also created a SQL query which unfortunately shows the same values
without getting too complicated is there a relatively simple way to display the min/max values from the long term & sensor data as per the graph
