I would like to read, perhaps in a sensor card, only the current_temperature attribute of a Meros thermostat, how can I do it?
Sensor cards do not support attributes. The Entity or Entities card does.
type: entity
entity: climate.termostato_homekit
attribute: current_temperature
If you really want to use the sensor card or some other card that does not support attributes you will have to create a template sensor from the attribute:
configuration.yaml
template:
- sensor:
- name: Current Temperature
device_class: temperature
state_class: measurement
unit_of_measurement: "°C"
state: "{{ state_attr('climate.termostato_homekit','current_temperature') }}"
availability: "{{ state_attr('climate.termostato_homekit','current_temperature')|is_number }}"
