I have created this climate:

- name: "Riscaldamento"
  unique_id: "termostato"
  modes:
    - "off"
    - "heat"
    - "cool"
  mode_command_topic: "home/riscaldamento_raffrescamento/TEST/mode/set"
  mode_state_topic: "home/riscaldamento_raffrescamento/TEST/mode/state"
  temperature_command_topic: "home/riscaldamento_raffrescamento/TEST/temp/set"
  current_temperature_topic: "home/riscaldamento_raffrescamento/TEST/temp/state"
  power_command_topic: "home/riscaldamento_raffrescamento/TEST/pump/set"
  payload_on: 1 
  payload_off: 0
  min_temp: 17
  max_temp: 28
  temp_step: 0.1
  precision: 0.1

thinking that the power_command_topic would be sent whenever the temperature would go over/under the one set, but nothing ever get send to that topic. How can I turn on the pump when the temperature goes under the one set and turn it off when it goes over?

Don't I need at least one to read the temperature from MQTT? Or can I just use an MQTT sensors? How?

here is my config yaml for climate. added hint for your case but i never had heat pump, does your heat pump only heat or does it also cool? exemple here is ok if only heat. If yours heat/cool, try some of the hacs thermostat addon. A quick search led me to this https://community.home-assistant.io/t/generic-thermostat-switch-between-heating-and-cooling/420053 which point to https://github.com/swingerman/ha-dual-smart-thermostat but i know they are more hacs addon for thermostat, you may need to search which is good for your use if the one above doesn't suit your needs

climate:
  - platform: generic_thermostat
    name: Thermostat Chambre (Riscaldamento)
    heater: switch.radiateur_chambre (device to toggle your heat pump)
    target_sensor: sensor.sonde_chambre_temperature (your temp sensor)
    min_temp: 12
    max_temp: 21
    ac_mode: false
    target_temp: 19
    cold_tolerance: 0
    hot_tolerance: 0.1
    min_cycle_duration:
      seconds: 300
    keep_alive:
      minutes: 3
    initial_hvac_mode: "off" (set this to heat if you want it to be active when HA start/reboot)
    away_temp: 12
    precision: 0.1

I'm trying to use the generic thermostat:

climate:
  - platform: generic_thermostat
    name: termostato_raffreddamento
    heater: switch.valvola_climatizzazione
    target_sensor: sensor.aqara_temp_sala_temperature
    min_temp: 24
    max_temp: 28
    ac_mode: true
    target_temp: 26 
    cold_tolerance: 0.1
    hot_tolerance: 0.1
    min_cycle_duration:
      seconds: 300
    keep_alive:
      minutes: 3
    initial_hvac_mode: "off"
    away_temp: 28
    precision: 0.1

But I only have the button to turn it off:

If I click it nothing happens. What have I done wrong?

on your card, click on the three dots. You should have more options there. If it doesn't work, change "intial_hvac_mode" to "cool"

edit: didn't see your next replied, glad you work it out
