Is there a way to show a zone in a history graph that is +/- a value around a reading without creating template sensors for the those values? I’d like to show something like the statistics max/mean/min but define the value myself.
It would be nice to be able to use template values in the history graph for this like below
- type: history-graph
templates:
- "{{ states('sensor.pool_monitor_pool_water_temperature') + myvalue }}"
- "{{ states('sensor.pool_monitor_pool_water_temperature') - myvalue }}"
entities:
- sensor.pool_monitor_pool_water_temperature
