MQTT Chart Persistence no results are saved

I am using ESP8266 to read Temperature and Humidity from a DHT22 over MQTT and what to show the Chart but somehow it does not save the state of the temp, hum.

My mqtt.item:

Group WeatherIO
Number Indoor_Temp "WZ Temperatur [%.1f]" <temperature> (WeatherIO) ["CurrentTemperature"] {mqtt="<[mosquitto:home/temperature:state:default]"}
Number Indoor_Hum "WZ Feuchtigkeit [%.1f]" <humidity> (WeatherIO) ["CurrentHumidity"] {mqtt="<[mosquitto:home/humidity:state:default]"}

My mqtt.sitemap:

sitemap mqtt label="Home" {
        Frame label="Chart" {
                Text item=Indoor_Temp {
                        Chart item=Indoor_Temp period=h refresh=10
                        Chart item=Indoor_Temp period=d refresh=10
                }
                Text item=Indoor_Hum {
                        Chart item=Indoor_Hum period=h refresh=10
                        Chart item=Indoor_Hum period=d refresh=10
                }
        }
}

My mqtt.persist

Strategies {
   everyMinute  : "0 * * * * ?"
   everyHour    : "0 0 * * * ?"
   everyDay     : "0 0 0 * * ?"
   default = everyChange
}

Items {
   * : strategy = everyChange, everyHour
}

The Log:

Installed are the Addons MQTT Persistence and RDDJ4 Persistence. Any ideas?
