Widget Request — VRV / VRF Control Widget

[savaskorkmaz]

Hello,
We would like to request a modified version of the existing Thermostat Widget, designed specifically for VRV / VRF air-conditioning systems.
VRV / VRF systems are the primary heating / cooling solutions used across the Mediterranean region and many nearby countries, and they dominate most of our smart-home projects. Because of this high usage, a dedicated widget is extremely valuable for our installations.
I have described the required widget parameters below, and I have also attached a visual mock-up showing the configuration layout and options for Visu Admin.

Main Differences from the Standard Thermostat Widget

1. “Force on when changing mode or setpoint” option will not be included.
   

---

Mode Selection Section
If Show Mode Selection is enabled, the Operation Modes section becomes visible.
There will be two selectable mode formats:

• 1-Bit Operation Mode
  
• 1-Byte Operation Mode
  

1-Bit Operation Mode

• The Reverse Cooling / Heating option becomes active.
  
• Depending on the value (0 or 1), heating and cooling states will be reversed.
  

This is necessary because some installations use inverted logic.
1-Byte Operation Mode
Users will be able to manually enter values for each mode:

• Cooling
  
• Heating
  
• Humidifier
  
• Fan
  

Since different manufacturers use different byte values, we must be able to define — for example — whether Cooling = 0, 1, 2, etc.
These values should be editable in the widget configuration.

Fan Speed Selection Section
If Show Fan Speed Selection is enabled, the Fan Speeds section becomes visible.
Fan speed format options:

• 1-Bit Fan Speeds
  
• 1-Byte Fan Speeds
  

1-Bit Fan Speeds
Selectable speeds:

• Speed 1 → Speed 4
  

For each enabled speed:

• 1-bit control object
  
• 1-bit status object
  

will be mapped in the Objects tab.
For example, if Speed 1 to Speed 4 are enabled, the widget should support:

• 4 × 1-bit fan speed control objects
  
• 4 × 1-bit fan speed status objects
  

(total 8 objects).

---

1-Byte Fan Speeds
Selectable options:

• Speed 1 → Speed 4
  
• Auto
  

For each option, the user can manually enter the value that will be written to the 1-byte object.
Additionally, fan byte format options should support:

• Scaled value
  
• Unsigned integer
  

(or alternatively, these datatypes may be selectable directly in the Objects tab).

---

Auto / Manual Selection Section
If Show Auto-Manual Selection is enabled:

• One 1-bit Auto / Manual object will be added.
  

There will also be a:

• Reverse Auto / Manual option
  

This allows sending:

• 0 = Auto / 1 = Manual
  or
  
• 1 = Auto / 0 = Manual
  

depending on the device requirements.

---

Summary
This widget will allow LogicMachine to be fully compatible with a wide range of VRV / VRF indoor units, by supporting:

• brand-dependent byte mode values
  
• selectable fan control styles
  
• reverse logic options
  
• Auto / Manual control
  

All of which are necessary in real-world VRV / VRF automation projects.
Thank you in advance for considering this request — we believe this widget will be highly useful for many system integrators working with VRV / VRF systems.
