I am using OH 2.5.10 and installed the AVM FRITZ! Binding.
As first thing for this binding I bought a magnetic door/window contact (HAN_FUN_CONTACT) https://www.smarthome.de/geraete/smarthome-tuer-fensterkontakt-magnetisch-weiss.
I’ve paired the device with the Fritzbox and then created the thing in OH. Everything works well.
But when the contact has an action (OPEN/CLOSED) it takes 10-15 sec for OH to get a notice of the action. This is not useful for my planned project (sending a push message when the mailman opened the mailbox which is observed by the window contact).
Any idea why this takes so long?
