Hey,

I'm trying to build a solar forecast plugin. I'm nicely adding data to the unit but it doesn't create the aggregated views. What am I doing wrong? I tried all of the commented out Options (yes, I deleted the device first)

Creating device

Code: Select all

        if self.deviceId not in Devices or (1 not in Devices[self.deviceId].Units):
            #Options={"AddDBLogEntry" : "true", "DisableLogAutoUpdate" : "true"}
            #Options={"AddDBLogEntry" : "true"}
            #Domoticz.Unit(Name=self.deviceId + ' - 24h forecast', Unit=1, Type=243, Subtype=33, Switchtype=4,  Used=1, Options=Options, DeviceID=self.deviceId).Create()
            Domoticz.Unit(Name=self.deviceId + ' - 24h forecast', Unit=1, Type=243, Subtype=33, Switchtype=4,  Used=1, DeviceID=self.deviceId).Create()

Adding data

Code: Select all

                if dateline.date() > date.today():
                    sValue = str(json["result"]["watts"][dtline])+";"+str(json["result"]["watt_hours_period"][dtline])+";"+str(dtline)
                    #sValue = "-1;"+str(json["result"]["watt_hours_period"][dtline])+";"+str(dtline)
                    # Domoticz.Debug("sValue = "+str(sValue))
                    self.UpdateDevice(self.deviceId, 1, 0, sValue)


    def UpdateDevice(self, Device, Unit, nValue, sValue, AlwaysUpdate=False, Name=""):
        # Make sure that the Domoticz device still exists (they can be deleted) before updating it
        if (Device in Devices and Unit in Devices[Device].Units):
            if (Devices[Device].Units[Unit].nValue != nValue) or (Devices[Device].Units[Unit].sValue != sValue) or AlwaysUpdate:
                    Domoticz.Debug("Updating device '"+Devices[Device].Units[Unit].Name+ "' with current sValue '"+Devices[Device].Units[Unit].sValue+"' to '" +sValue+"'")
                    if isinstance(nValue, int):
                        Devices[Device].Units[Unit].nValue = nValue
                    else:
                        Domoticz.Log("nValue supplied is not an integer. Device: "+str(Device)+ " unit "+str(Unit)+" nValue "+str(nValue))
                        Devices[Device].Units[Unit].nValue = int(nValue)
                    Devices[Device].Units[Unit].sValue = sValue
                    if Name != "":
                        Devices[Device].Units[Unit].Name = Name
                    Devices[Device].Units[Unit].Update()
                    
        else:
            Domoticz.Error("trying to update a non-existent unit "+str(Unit)+" from device "+str(Device))
        return

Not looking at the code but are you using a managed counter? Then you need to build the history from the plugin. Domoticz core will not do that for you.

Perhaps check a plugin for future energy prices how they implemented that?

Edit: see the wiki:
sValue must 3 semicolon separated values, the last value being a date ("%Y-%m-%d" format) to update last week/month/year history, for instance "123456;78;2019-09-24"

OK, so that is actually the sValue input. See logging below:

Code: Select all

2025-03-29 19:55:31.036 Solar forecast achter: sValue = 418;289;2025-04-01 19:00:00
2025-03-29 19:55:31.036 Solar forecast achter: Updating device 'Solar forecast achter - 24h forecast' with current sValue '' to '418;289;2025-04-01 19:00:00'
2025-03-29 19:55:31.067 Solar forecast achter: sValue = 0;247;2025-04-01 20:10:47
2025-03-29 19:55:31.068 Solar forecast achter: Updating device 'Solar forecast achter - 24h forecast' with current sValue '' to '0;247;2025-04-01 20:10:47'
2025-03-29 19:55:31.100 Solar forecast achter: sValue = -1;6833;2025-03-30
2025-03-29 19:55:31.100 Solar forecast achter: Updating device 'Solar forecast achter - 24h forecast' with current sValue '' to '-1;6833;2025-03-30'
2025-03-29 19:55:31.132 Solar forecast achter: sValue = -1;9224;2025-03-31
2025-03-29 19:55:31.132 Solar forecast achter: Updating device 'Solar forecast achter - 24h forecast' with current sValue '' to '-1;9224;2025-03-31'
2025-03-29 19:55:31.164 Solar forecast achter: sValue = -1;18478;2025-04-01
2025-03-29 19:55:31.164 Solar forecast achter: Updating device 'Solar forecast achter - 24h forecast' with current sValue '' to '-1;18478;2025-04-01'

First lines give the hourly updates, last lines the full day updates

I am not sure how this works for using a managed counter as forecast device but I suppose it is only visible in the short log data (top graph). The other graphs probably only show real history data (but again, I am not sure)

OK so it works now. However, I'm entering future day data but that is not being displayed. Is there any device that lets me display (aggregated) future data?

What I want, is to load this predicition data and use it in another script to determine the best operating mode for my home batteries. I think it should not be in a combined plugin as the target operating mode depends on data from both the devices that give the electricity prices as well as the predicted solar energy and then controls the battery. These are 3 different plugins. So any advice on how to do this is welcome.

So this is what the graph looks like (now is April 1 21:06)
