I have noticed that two of my Z-wave devices (one Fibaro switch 2 and one Telldus wall plug) have start to fail, in this case not turning their lights bulbs off. It seems that all this started after the update to V2.1.2. Before the update all flows was working flawless . Controlling the lamps through the devices in Homey works, but it seems that when they are in a flow the problem starts. Strange thing is that the devices turn the lamps on without any problems but always fail to turn the lamps off when in a flow.
Have anyone experienced the same?
