    Hi,

    I have C-bus that is now coming up to 11 years old.
    6 months ago I got a new Wiser 2.
    Yesterday I arrived home and every single light (about 150) had turned on ......

    Any ideas why ?

    The most likely cause of every light coming on is the 'remote on' pair being activated. Cbus cable uses all 4 pairs of the network cable. Two of the pairs are in parallel and carry the main cbus comms. The other 2 pairs are simple 'remote on' and 'remote off' switches which will turn everything on or off. They are not used in domestic installations but many installers wire them up by default (since they are just a part of the rj45 connector). A short or even a bit of moisture or ingress by wildlife anywhere in the network can trigger a remote on. If you have any outdoor cbus equipment or any obvious water leaks, this is the place to start looking.
