Neither after restarting the phone nor after restarting RFBridge is the history saved.
My history log is empty since end of July.
Doesn't record any alarms since then.
A friend has the same.
So it's not us, it must be Ewelink or ???
Pretty useless device now !!!
BTW: I'm in the EU.
This morning I found out that history is being written down. The problem is probably fixed. The error was apparently on the application side.
