Force Sensor Polling
fillibar:
Yes, of course I know that (but thanks for double checking). I also know enough customer support stories to not be insulted by the question.
The problem is not that I cannot control them, but that I do not "know" I cannot control them from the app. It does not say "failure to communicate" or some such... It says "On"... I know they will not work, but nobody else in my house will understand why not until it takes me longer to explain then it would for me to turn them on manually.
LGNilsson:
It should be possible to do this with mains powered sensors, but it'll be very hard with battery powered devices.
I've brought this up with the software team, but we're going to have to take a better look at how we can do this.

It would be nice to at least have some kind of indication.
I have a sensor assigned that has not had a battery connected to several months, and it is happily showing a status of Open.
My Home alarm while it is using some kind of Proprietary wireless communication will report if a sensor lost contact.
In my previous apartment I actually had one of the reed sensors driving me nuts, it was in a outside storage room, just within range, but during the winter I suppose when the temperature dropped, I would frequently (about once an hour) get an SMS that the Alarm lost connection, and then another SMS that it had re-established connection.
So it did do some kind of polling, and although not ZigBee or Z-Wave, it used the same type of batteries as the Securifi sensors do and has about a year and a half battery life.
On the Vera Wiki is a section about polling, and it seems at least for Z-wave that the sensors decide if they can be polled.

ZigBee HA profile seems to have a 7,5 sec polling rate according to this book.
