I have 2 entities for temperature. One from MQTT integration, from Sonoff humidity&temp sensor and another is a min_max sensor for an average of several temperature sensors. During the history view, they are in a different charts so it is harder to compare them.
I understood the measurement type is the one that "decides" if charts are grouped or not. But I must be failing something. My configuration for min_Max sensor is below and the MQTT sensor is on the picture
- platform: min_max
unique_id: home_indoor_average_temperature
name: Average Home Indoor temperature
type: mean
round_digits: 1
entity_ids:
- sensor.sensor_1
- sensor.sensor_2
- sensor.sensor_n
Edit: wrong title. It is not template, it is min_max sensor.
