    We're having an intermittent problem where adjacent dimmer channels (L5504D2A or L5508D1A, LED fittings, no load correction) seem to "link" internally. That is, if you turn on channel 1, channel 2 will also come on (and vice versa). We've not worked out the trigger, but when it does happen it seems to persist until one of the wires to the fittings is disconnected and reconnected. This applies whether via group address or manual override buttons.

    Any clues what is happening and how to resolve it?

    As I cannot reproduce the problem on demand I'm wary of just trying things (eg load correction) without any way of knowing whether it has helped.

    (All units are new, and we've seen it on multiple units so I suspect it's fitting related, but I've not seen issues on one channel affecting an adjacent one before.)
