I have problems with the Net- event (network disconnect). It seems that this is only triggered, if the network is disconnected from a timeout and not, if you disconnect it on your own. But it worked since a few days. I also tried to deinstall and install a fresh apt. I only added this one trigger Net- and it only work on a timeout. I don't know, whether I have changed something the last days. Maybe someone other can try it.
I have a TX and tried it with wifi: Net- -> App -> Whatever
After the timeout (3 min) whatever is started
If I close the connection on my on, its not called.
