Question on data graphics child devices

[matsys 0]

I sее a problem that when you create child of the device by LUA in QApp HC3, in parent device displays a graph of changes of values, but the child - do not. At the same time, there is a "save history" checkbox. What could be the problem?

Welcome to the forum @matsys

 

Graphs in the advanced settings of a device depend on the device type. 

 

Can you tell us more on what you are doing? Share your code?

So, i read data from temperature-humidity sensor by Modbus TCP.

 

I have parent device - temperature sensor and 1 child: humidity sensor

 

Some code (not full in order not to overload, but the principle itself was clear)

 

-- Multilevel switch type should handle actions: turnOn, turnOff, setValue
-- To update multilevel switch state, update property "value" with integer 0-99
class 'humSM5310'(QuickAppChild)
function humSM5310:__init(dev)
  QuickAppChild.__init(self,dev)
end
function humSM5310:updateValue(data)
  self:updateProperty("value", data.hum)
end

 

function QuickApp:updateChildDevices()
  for id,child in pairs(self.childDevices) do -- Update Child Devices
    child:updateValue(data) 
  end
end

-- Value is type of float
function QuickApp:setValue(value)
    --self:debug("multilevel switch set to: " .. tostring(value)) 
    self:updateProperty("value", value)    
end

 

-- Setup child

 

function QuickApp:setupChildDevices()
  local cdevs = api.get("/devices?parentId="..self.id) or {} -- Pick up all Child Devices
  function self:initChildDevices() end -- Null function, else Fibaro calls it after onInit()...

  if #cdevs == 0 then -- If no Child Devices, create them
    local initChildData = { 
      {className="humSM5310", name="Hum sm5351", type="com.fibaro.humiditySensor", value=0},
    }
    for _,c in ipairs(initChildData) do
      local child = self:createChildDevice(
        {name = c.name, type=c.type, value=c.value, initialInterfaces = {}, }, 
        _G[c.className] -- Fetch class constructor from class name
      )
      child:setVariable("className",c.className)  -- Save class name so we know when we load it next time
    end   
  else 
    for _,child in ipairs(cdevs) do
      local className = getChildVariable(child,"className") -- Fetch child class name
      local childObject = _G[className](child) -- Create child object from the constructor name
      self.childDevices[child.id]=childObject
      childObject.parent = self -- Setup parent link to device controller 
    end
  end
end

 

 

So, first i create child device - humidity sensor and from time-to-time reload value, and all is ok display, but no graphics on this child device, and parent (temperature) device - have graphics.

Device types com.fibaro.humiditySensor don’t have the graphs like for example the temperature, power devices have.

Thanks! Where can I look at all types? Is it listed somewhere?

yes, there is, over here:
