Wiser and Wiser HD app with Wiser and PAC

Would anyone be able to explain the reason why neither of these apps are reporting back the correct state of lights on opening? The apps always seem to report that lights are on that are off and vice versa.
My understanding was that CBus was a very robust and reliable system and yet whenever I open the app the wrong lights are showing as being on (or off?!)
Appreciate any guidance as it makes checking on the state of the lights when I’m outside the house really hit and miss.
Thanks

 

is it a multi network installation or single network?
could be many things, network voltage, network noise, poor ip network settings or firewalls,
cbus interface of the wiser. are there any other issues using wall switches

 

Is it reporting the last state they were at when the device was turned off. Give it time to sync to the current status perhaps
