Heatit Z-Water unreliable?

Question

A few days ago, I installed a HeatIt Z-Water relay unit for my heating system. Inclusion in HC2 worked nice (after a couple og exclusion/Inclusion av usual) but the HC2 looses communication after a few hours. All I need to do to get it up and running is to manually change the status of one of the outputs. 

 

Have contacted the manufacturer but they say they never have experienced problems with this unit (and of course I believe them :-(

 

My HC2 is updated to versjon 4.510 prior to installation of the Z-Water so I don't know if it worked in previous versions but the 4.510 have made a few odd tings to my house...

 

Any other having trouble with the Z-Water?

  • To be more accurate: To get it up and running again, I need to tap on the "X" indicating dead device in the Android app, not only change the status of one output in web-ui.

  • I made a quick and dirty scene to wake the Z-Water up when it goes to sleep:

    ID 343 is the first output in the unit.

     

    For some reason, the "fibaro:wakeUpDeadDevice(343)" only worked every now and then but "fibaro:call(1, 'wakeUpAllDevices', 343)" works every time.

     

    Debug output is only for me to have an idea on how often it fails. The last 90 minutes, it have died 5 times and that is far more than usual..

     

    With this scene, the Z-Water is working fine but the scene is only covering up the problem, not solving it...
