Plugin Python :how update SignalLevel and BatteryLevel (and custumImage)

[zaraki673]

Hi everybody!!

For a plugin, i need to update the BatteryLevel to devices in domoticz
To do it, i have update the UpdateDevice code like that :
before :

Code: Select all

def UpdateDevice(Unit, nValue, sValue):
	# Make sure that the Domoticz device still exists (they can be deleted) before updating it 
	if (Unit in Devices):
		if (Devices[Unit].nValue != nValue) or (Devices[Unit].sValue != sValue):
			Devices[Unit].Update(nValue, str(sValue))
			Domoticz.Log("Update "+str(nValue)+":'"+str(sValue)+"' ("+Devices[Unit].Name+")")
	return

after :

Code: Select all

def UpdateDeviceWithBattery(Unit, nValue, sValue, CustomImage, SignalLevel, BatteryLevel):
	# Make sure that the Domoticz device still exists (they can be deleted) before updating it 
	if (Unit in Devices):
		if (Devices[Unit].nValue != nValue) or (Devices[Unit].sValue != sValue) or (Devices[Unit].SignalLevel != SignalLevel) or (Devices[Unit].BatteryLevel != BatteryLevel) :
			Devices[Unit].Update(nValue, str(sValue),CustomImage, SignalLevel, BatteryLevel)
			Domoticz.Log("Update "+str(nValue)+":'"+str(sValue)+"' SignalLevel:"+str(SignalLevel)+" batteryLevel:'"+str(BatteryLevel)+"%' ("+Devices[Unit].Name+")")
	return

As you can see, i also update the CustumImage attribut, but i didn't find how to get it back from domoticz's DB, so i can't check if the value have change

If anyone know how to get it ...

@zaraki673,

At the end of the Device.Update() call the python framework reloads all the device details from the database for you and refreshes the Device object contents. This means that if the Device[Unit].Image is set to what you want, the database update was successful (although Device.Update() will return an error if it fails anyway).

If you are really worried you can call Device[Unit].Refresh() inside your plugin to manually force a device refresh but it shouldn't be required because all updates should be driven by the plugin itself.

Sorry to answer so late,

Thank you for your answer, I undestand what you said, the only think i miss was 'Device[Unit].image' as customImage (name in DB).

now all seem to work fine
