Is there such a thing like a re-transmit binding for wireless communication ?
When I send a command, it keeps sending it every x seconds until the state changes accordingly. (no autoupdate)
Example: I set the rollershutter level to 50 with a command. The state remains until the shutter reports back the new state. Thats how it is already. What I miss is an automatic re-transmit of that command if the state does not change within x seconds.
I would love this to be similar to the expire binding. When it still was a binding that is.
Rollershutter “Bathroom” … {channel=" …", retransmitt =“10s,3,updatedItem”}
Yes, I know how to do this in python or with Timers. I just thought this may be a nice thing to support out of the box since wireless or other lossy forms of communications do happen
Something like this would have to be implemented in core I think because the bindings do not really have access to Items in OH 2.x+ architecture. That’s why Expire was moved into core.
Ideally, this should be built into the add-on because retrying isn’t really applicable to all technologies.
It also gets complicated when an Item is linked to multiple channels and if profiles get involved.
This would be a great candidate for a rule template though. Put all the Items into a group, add the “retransmit” metadata to those Items and one rule can do this. Published to the marketplace, and it becomes installable like an add-on.
