Hi Folks,
Since the update of the android app to v 2.8.0 slider and setpoints deliver the value in float format instead of integer.
The tahoma binding, I use for my blinds and rollershutters, goes offline if it has to deal with floats.
My question is, how can I force the slider or setpoint send integer format?
I had a similar issue with my speaker connected via http binding.
Have you tried updating to 2.9? This solved at least my problem
If you read the linked thread, it tells you -
A) it’s a binding bug really. If you create a github isdue for the binding, it could get fixed properly.
B) as a temporary workaround, the android app author has made a new app version
C) if you like neither suggestion, you can use a proxy Item on your UI and have a rule update your bound Item with an integer
Sorry if I’ve written some mistakable.
I see that the binding has troubles with float numbers. But I’m just searching for a lazy solution. A kind of formater for sitemap values?
The next step will be an issue in github, of course.
No, unfortunately not 
Still get log messages like

The simplest workaround is defining the item labels in integer format: Number MyItem "My Item [%d]"
But yes, a binding must be able to deal with Number items in both integer and float format … I explicitly asked Kai about that, and he stated so.
YMMD 
[%d] solved it.
