Climate to turn on/off heat pump (self.homeassistant)

submitted 9 months ago by peregus to c/homeassistant

16 comments fedilink hide all child comments

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?

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

[–] peregus 1 points 4 months ago

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!)

[–] [email protected] 1 points 6 months ago (1 children)

Instead of using a community add-on, you can create two generic thermostat. https://www.home-assistant.io/integrations/generic_thermostat/

[–] peregus 1 points 6 months ago (1 children)

Mmm...ok. Do you think that there is a way to hide one of them based on the season?

[–] [email protected] 1 points 6 months ago

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.
