Hi all,
searching for a DECT-ULE flood sensor I came across this announcement (sorry only in German) for new HAN-FUN devices for the AVM Fritzbox:
There are currently two devices available:
- a flood sensor (OWSM-1)
- and a 2-channel switch (OWWT-2-UP)
I bought me an OWSM-1 to play around and replacing an unreliable solution with Shelly flood sensors (to prevent any misunderstanding: the Shelly sensors are great but I am running OH in a docker environment and this does not work properly with the Multicast UDP-Traffic that is used by the Shelly flood sensors for the CoIoT communication). I tested OWSM-1 successfully with the Fritzbox functions only. It switches my DECT rollershutter when it detects heavy rain outside. I will get me second flood sensor now and a switch to test with my non DECT rollershutters 
OwangO Media Network will announce additional HAN-FUN DECT-ULE devices coming in the mid of July for environmental (weather) data … I thought this might be interesting to others too. And depending on the resonance we might get binding support into OpenHAB at some time in the future as well
