When I go to the "C-Bus status" tab of any of the Multi-sensors on my network I get the message "Unit not found at this address on the network". Functionality does not otherwise seem to be a affected, I can change and update any other information with it saving to the sensor but I cannot view its status. External and corner mount sensors all come up fine. Any thoughts ? Also, when using a remote control and a multi sensor can you control lights using the "dimmer" function. When I assign the dimmer function to a virtual key I get erratic results, sometimes the lights come on full, sometimes they turn off but mostly nothing happens. I can set scenes and use on/off without any problems but the multi sensor seems to have problems recognising the longpress on the remote.
