Advice reqeusted to migrate MSR from Bare Metal to Container

[noelab]

Hi, I tried with my skills and no luck, so I want understand if it is possible.

if I create a Global variable, for example to have a Thom Index value

xB1_Thom_Index_ID = round( float( xB1_Temp_01_ID ) - (0.55-0.0055 *  float( xB1_Humidity_01_ID )) * ( float( xB1_Temp_01_ID ) - 14.5) , 1)

and then I create a Virtual Entity that show the updated value also on the dashboard every time xB1_Thom_Index_ID changes

seems that this is not the right way

          id: testA_dynamic_vec
          name: TestA Dynamic Vec Value
          capabilities:
            value_sensor:
              attributes:
                value:
                  expr: xB1_Thom_Index_ID

nothing

          id: testA_dynamic_vec
          name: TestA Dynamic Vec Value
          capabilities:
            value_sensor:
              attributes:
                value:
                  expr: round( float( xB1_Temp_01_ID ) - (0.55-0.0055 *  float( xB1_Humidity_01_ID )) * ( float( xB1_Temp_01_ID ) - 14.5) , 1)

I get the value updated only when MSR restart. Is this way totally wrong?

Thanks in advance

@noelab said in Virtual Entities (value or string) can auto update based on a Global variables?:

seems that this is not the right way

That actually is the right way. You may have found a bug. I'd like to see the rest of the expressions involved, though. I need to see all of the global variables mentioned in your expression (and any they mention).

Global expression

xB1_Temp_01_ID = getEntity( "ezlo>device_626d5f9f129e2912444634a4" ).attributes.temperature_sensor.value

xB1_Humidity_01_ID = getEntity( "ezlo>device_626d5f9f129e2912444634a0" ).attributes.humidity_sensor.value

in reactor.yaml

-
          id: testA_dynamic_vec
          name: TestA Dynamic Vec Value
          capabilities:
            value_sensor:
              attributes:
                value:
                  expr: round( float( xB1_Temp_01_ID ) - (0.55-0.0055 *  float( xB1_Humidity_01_ID )) * ( float( xB1_Temp_01_ID ) - 14.5) , 1)

in dashboard

[noelab]

or

glabal expression

xB1_IndiceThom_ID = round( float( xB1_Temp_01_ID ) - (0.55-0.0055 *  float( xB1_Humidity_01_ID )) * ( float( xB1_Temp_01_ID ) - 14.5) , 1)

reactor.yaml

        -
          id: testA_dynamic_vec
          name: TestA Dynamic Vec Value
          capabilities:
            value_sensor:
              attributes:
                value:
                  expr: xB1_IndiceThom_ID

dashboard

Great. Thank you. Two things going on here. One you can fix, one I have to fix.

First, you have to help the dashboard figure out how to display your entity. For that, you need to make two additional entries in your config for your virtual entity. Add the two lines I show at the end here:

          id: testA_dynamic_vec
          name: TestA Dynamic Vec Value
          capabilities:
            value_sensor:
              attributes:
                value:
                  expr: xB1_Thom_Index_ID
          primary_attribute: value_sensor.value
          type: ValueSensor

Setting primary_attribute helps the dashboard figure out which attribute to display. The type determines the widget type, which can be:

• Switch — an on/off switch;
• Light — a dimmable light or multi-level switch;
• Valve — a water valve;
• Lock — a door lock;
• BinarySensor — a binary sensor;
• SecuritySensor — a security sensor (special case of binary sensor for door, window, glass break, etc.);
• Button — a pushbutton (entity must have button capability);
• Script — a script (like a Vera scene, Hass automation or script, etc.);
• MediaPlayer — a media player (has media_player and other related capabilities);
• Camera — a camera;
• Weather — weather entity (implements wx capability);
• Cover — window covering, garage door, etc.

Now, that said, there is indeed a bug in handling attribute changes. It appears VirtualEntityController is aware the variable has changed, but it's consistently getting the previous value rather than the new value for the expression, and I know what's causing that. It will take a couple of days for me to fix and get out a new build.

Thanks to you!!!
Lines are added

another idea for the future:
a gauge range applied to ValueSensor or Weather in simple text color:
RED text for value out of range min/max

Can you tell me what your Reactor install is? Docker? What architecture?
