Hi all,
i try to rebuild the online monitor from the FritzBox to check my Up-/Downstream with openHAB.
First I tried to use the values “fboxDslUpstreamCurrRate” and “fboxDslDownstreamCurrRate” till I found out, that they are only the given numbers of the provider.
My next Idea is to use the “fboxWanTotalBytesReceived” Value to calculate my downstream within a rule, but my values look not correct,…
Here is what I tried to get the current Downstream in kBit/s:
Currently I’m working on exactly the same goal, but I’m not there yet…
But what I can tell you right now: the unit of your variable downloadCurrent would be kByte per second, but you compare it to kBit/s. Thus to get kBit/s the line should be: downloadCurrent = fboxWanTotalBytesReceived.deltaSince(now.minusSeconds(1)) * 8 / 1000
Problem is: this number would be even higher and you say, your current value already is higher on your FritzBox.
Another idea: you compare the value fboxWanTotalBytesReceived with the value a second ago. The default refresh interval is 60000 ms per default. Have you changed it to 1000 ms? Or are you comparing your current value with a value 60 s ago? That would be an explanation for your high values.
For verification, I just used the values written in events.log, 2020-04-28 15:14:49.036 [vent.ItemStateChangedEvent] - fboxWanTotalBytesReceived changed from 5675675 to 150062945 2020-04-28 15:15:55.605 [vent.ItemStateChangedEvent] - fboxWanTotalBytesReceived changed from 150062945 to 293525632
With these numbers youl’ll get: `(293525632 - 150062945) * 8 Bit / (67 seconds * 1000) = 17130 kBit/s which is the same magnitude I see in my Online Monitor.
Btw, pay attention as this value is an Int32. Therefore it overflows at 4294967295 which you have to catch.
