Help! thermostat control by automation

Installation Home Assistant OS
1

Hi guys,

i am new here and already deep in love with Home Assistant.
I have a scenario at home and hopefully somebody can help me out.

I got room 3 Wall heating units in one Room, all controlled by a entity. I also got a wall control until in the same room. I like to connect them so I control the room temperature by the wall device . I guess that’s done via automation??!!

I like to set the Temperatur on the wall and all three wall devices change. I have all entity in my system I just can’t connect them.

So 1 room with 3 separate heaters and 1 thermostat (or thermometer ?)
Do the heaters have their own switches ? (I assume they are electric ?)
Or are they all switched together ?
Are ALL the above devices visible to HA ?
What are they called (device id’s) ?
What are your units ? (°C or °F) ?
Do you have door/window sensors ?
Have you got Occupancy working yet ?
Do you want to have a temperature profile ?
e.g. Door Open : 4°
Away : 10°
Night : 14°
Day : 17°
Evening : 18°

I leave my heating on all year round but with these setpoints it didn’t come on until Mid September and then only for three hours, October it was on most days and …

Do the heaters have their own switches ? (I assume they are electric ?)

yes electric

Or are they all switched together ?

no the switches on the heating are all controlled separate.

Are ALL the above devices visible to HA ?

yes they are

What are they called (device id’s) ?

the three wall switches are:
climate.tanzstudio_fenster_links_510
climate.tanzstudio_fenster_rechts_506
climate.tanzstudio_wand_514

wall switch:
climate.tanzstudio_status_614

What are your units ? (°C or °F) ?

C

Do you have door/window sensors ?

i do but its not important for now.

Have you got Occupancy working yet ?

no

Do you want to have a temperature profile ?

also not important for now.

Its a dance studio with lots of people traffic.

thank you for your help!!!

You then show a picture of a TRV (thermostatic regulating valve) which operate on water systems to control hot water flow to a radiator.

I’m confused

Switches for electric heating elements would generally look like “switch.bedroom2heater” not have a climate domain entity ?

Sorry I might use the wrong words. Bare with me I am new to this :slightly_smiling_face:

Yes I do have those heating control as seen in the pictures on my heaters controlling the water flow in the units. I like to control all three of them by my wall unit also seen in the picture.

I’m trying to figure out as similar situation. I have several rooms heated via a central heating boiler. Currently the boiler is controlled via a timer and a Danfoss RF thermostat, which I hope to replace with a Z-Wave thermostat soon. I have Devolo TRVs installed on the radiators, but don’t know how to set up Home Assistant so that I can add similar Z-Wave thermostats to the other rooms, and call for heating when any of the rooms are below their target temperature.

I thought I could do something with an input variable, so that I can set the temperature either in Home Assistant or through the controls on either device, and Home Assistant would keep both of the devices synced up. So far I haven’t been able to figure it out. I’ve attempted to set up a generic thermostat, but I currently don’t think it’s possible to do what I’m trying to do.

All this to say, I’m interested in whatever your solution ends up being, as I will have to implement something similar in due course.

Yeah same situation for me. I was hoping it can be done via automation. Hopefully somebody can help

Yes, that could be done via automation. You set a trigger on “state” change of the main thermostat and use json temperature attribute as a target temperature for the other thermostats you would like to sync.

- alias: Haupthermostat via Automation
  trigger:
  - platform: state
    entity_id: climate.HAUPTTHERMOSTAT
  action:
  - service: climate.set_temperature
    data_template:
      entity_id: climate.THERMOSTAT_1
      temperature: '{{ states.HAUPTTHETMOSTAT.attributes.temperature | float }}'
  - service: climate.set_temperature
    data_template:
      entity_id: climate.THERMOSTAT_2
      temperature: '{{ states.HAUPTTHETMOSTAT.attributes.temperature | float }}'
  - service: climate.set_temperature
    data_template:
      entity_id: climate.THERMOSTAT_3
      temperature: '{{ states.HAUPTTHETMOSTAT.attributes.temperature | float }}'
