Newbie - Grouping Thermostats

Hi

I’ve been searching and searching, and cannot find a simple answer to simple question. (to me its not that simple)

I want to control multiple Danfoss Living Connect Thermostats without having to adjust every single one of them. I have tried to install a virtual device through the Luup file D_HVAC_ZoneThermostat.xml and I_HVAC_ZoneThermostat.xml. This gives me just an “empty” device without any options. I have to add a parent device before i can add group where i can add the thermostats. But i get no choice of temperature settings. Do really have to install a LUUP file to control the Temperature? Or could a scene help me on that?

Sorry for the dumb question. Newbie :stuck_out_tongue:

Cheers

Hi,

you normally can use a scene to control more than one DSS to set the setpoint.

There you can select type “Thermostats” and use the second listbox to set the setpoint.

Hi

I cannot recognize the approch you are describing. I’m using UI5 and when i create a scene, i can only choose which device i want to control.

I can configure trigger, schedule, Luup. But i cannot see the option you’re describing. See pic.

When i make an advanced scene, i can choose the thermostats, but afterwards i have a scene with no posibility to set the temperature.

When in the scene creation, click on the climate tab and select your thermostats you want to control.

Hi

For some reason my Danfoss thermostats are listed under “other”. Is it possible to change that? Could this be the reason why i don’t have the correct options? When i create a scene, i can of course se the thermostats under “other”, but i only have the option of clicking on “off”, “Heat”, +/- for setpoint, and a specifik temperature. But i cannot just select the thermostat. This can be achieved by adding the thermostats under advanced. But i still don’t have any option on the Scene afterwards. Under advanced i choose the function “SetCurrentSetpoint”.

In the scene setup, when changing any of the thermostat options for each thermostat, it will be included in the scene. So if you modify the temperature of all of your thermostats for that scene, all of those thermostats will be included in the scene and run when you either have a trigger, timer, or click on the run command. The scene editor is more like a what you see is what your get (WYSIWYG). As for changing the device type of the thermostat from other to under climate, you would have to modify the device file. Not sure what file the use. Can you provide a screen shot of the advanced tab for the thermostat? Or try changing one of the thermostats category number in the advanced tab to 5?

Hi Garrett

I don’t wan’t a specifik temperature controlled by a scene. I want the option of controlling the temperature for my whole livingroom with one “knob”. Like a virtual device that has the same look than a single thermostat device. And when i change the temperature from 23 degrees celsius to 19 degress, i change it on the virtual device, and it changes all the associated thermostats. (Like a single wall controller - Horstmann HRT4)

I don’t have the option “Category” under advanced. See my available options on the pictures attached.

If I understand correctly, you want to slave all your thermostats to a single knob. I’m interested in this as well, but I haven’t been able to make it work:

  1. Scene is triggered when a new temperature is dialed in
  2. Scene reads the new temperature from the master device
  3. Scene sets the temperature on all slave devices to the new value

Steps 2 & 3 are easy to achieve using Luup code. However I have not been able to get a scene to trigger when the temperature setpoint is changed; neither the virtual thermostat device nor the Horstmann device offer that option in the Vera UI.

I remember seeing some code that implied that it’s possible to “watch” a uPnP variable (such as the temp setpoint), and call a function if there’s a change, but I’ve no experience in using this. Maybe someone can help with that?

What if you created some startup Luup to just set all thermostats when the setpoint changes? Granted, it’s not a “single knob” solution, but it’s rather like having the same knob on all thermostats.

I’m sure I can’t write the code for this, but I thought I’d recommend a new approach. The code would probably resemble what mcvflorin provided to me for changing HEAT/COOL mode based on temperature setpoints.
