Presence Detection / Host Monitor with FritzBox's TR069 API

Hi, i found out that it should be possible to ask your fritzbox for online / offline hosts via mac adress and the TR069 API ?!
im not a coder, but im trying to play around with this API.

any ideas ?

I‘m looking into this as well. I don‘t like the idea of having all family members need the ST app for presence and the presence sensor on the key chain is not an option. So, I also thought of using the connection to the FritzBox as an alternative.
I actually started a SmartApp using TR069. Since I had other priorities I didn‘t get too far. But, I was getting some response back from the FritzBox, so I am sure it is possible. I will have another look at this option after I finish my eCozy Thermostat/TRV Device handler.
