Create item based on minimum value of two other items

[davorin (Richard Klingler)]

Good afternoon

I have two temperature sensors outside…and I want to create an item which represents the lower of both values…or take the value of one item if the other is offline…

Is that something doable?

Currently doing that on an esphome end device which I want to migrate over…

thanks in advance

Yes, via Item Group Aggregation.

Ah those odd configuration stuff I never understood so far…only used to UI configuration

This can be done in the UI too…

When you make a new group item choose a member type and an aggregation function.
