Hi. thank you for your answer. :)
The daily usage is completely correct. I restarted the router today. Now via modbus daily and weekly are the same values. In the webinterface they are different.
The adresses are correct as well. Because temperature, rssi and stuff are working. I guess I will use the daily since it is working and build the rest in HA with a daily, weekly (and so on) integration (math function).
