Climate MAX - how to add temp of two and get average

Hi there,
I do have a max climate, integrated into HA and working great.
No I do have several temp sensor on one room.
entity -> climate.alina_links

Attributes  like:
    min_temp: 4.5
    operation_list: auto,manual,boost,vacation
    current_temperature: 20.5
    operation_mode: auto
    friendly_name: Alina Links
    max_temp: 25
    temperature: 20
    unit_of_measurement: °C

and the same for entity climate.alina_rechts
the temperature of both do differ and what I would like is showing the average temp. So (T1+T2)/2. I thought I use a template sensor, but don’t know how to do this. Can anybody help?

Maybe the mean function of the min/max sensor?

but the values are no sensors, they are attributes???

In which case, take a look at the top of the page, where it explains how to use a template_sensor to do what you’re after :wink:
