Please provide the capability to specify how the associated sensors will be summed by associating a “+” (plus) or “-” (minus) sign with each sensor defined in the helper.
The second. Within the “sum” option of the “Combine the state of several sensors” helper please provide a feature that facilitates the association an arithmetic sign (either plus or minus; positive or negative) to each of the user-specified entities. My main goal, personally, is to be able to access this enhanced helper as a DIFFERENCE between two entities. My feature request would satisfy this goal and provide much greater flexibility to those that might wish to combine more than just two entities. However, I would be happy just to have a “difference” added to the helper that would allow calculation of the difference between just two entities, if that would be easier to code. I have decided to never perform scripting within HomeAssistant as that became a maintenance nightmare for me in previous years. Thank you for your consideration.
So, the statistical range option?

Can you do what you want with the Bayesian sensor?

We have discussed this in the past to add - capability but it was rejected due to technical “limitations”.
So it won’t be added and I would refer you to use a template sensor instead which is quite easy.
btw: min_max integration is going away in favor of group sensor.
