Climate to turn on/off heat pump

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?

Just use generic thermostat https://www.home-assistant.io/integrations/generic_thermostat/
- I think I will, I just wanted to avoid automation (it's getting pretty crowded there!) to read ambient temperature from MQTT
  
  I don’t have an answer for you, but this comment reminds me how badly home assistant needs to add subfolders for organizing and grouping our automations
  
  If I recall correctly, chances are they are coming this year
  
  Fingers crossed! I know one YouTuber I follow mentioned it in his “2024 predictions” - wasn’t sure if he was pulling ideas out of his butt or if there had been actual commitment to this idea. Your comment gives me hope it’s the latter!
  
  Can't recall which video (maybe "year of the voice chapter 5") but devs talked about it on official youtube Channel
  
  Unless you want some specific schedule, there is no need for automation, add config to yaml and it is good to go
  
  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
  
  I remove the feature "Climate HVAC mode" and added it again and now I can use it.
  
  I completely missed your reply, sorry. My system cools and heats, and I really would like to avoid addons to avoid possible brakes in future updates. Do you think that it would be possible to do it with automation? (They can finally be divided into categories!)
  
  Instead of using a community add-on, you can create two generic thermostat. https://www.home-assistant.io/integrations/generic_thermostat/
  
  Mmm...ok. Do you think that there is a way to hide one of them based on the season?
  
  You can use an helper to toggle from one to another and use an automation to trigger it (or a simple switch on your dashboard).
  
  But if I were you, I would use a community add-on as dual AC isn't a niche, I guess it will keep being updated in future. I've been using some community add-on for a couple of years and none have been dropped til now.
