Z-Wave Dimmers Activating Without Reason

Hi, I have a house full of z-wave switches and dimmers which are all working very well with Indigo and Homekit; except for two dimmers in particular which are very problematic. The problem is they randomly turn on quite frequently, sometimes off as well but generally on. This is particularly a problem in the master bedroom. I've enabled the debug logs and i can see that the devices seem to think they're being activated, though they aren't. Strangely i find if i reboot the mac mini that hosts indigo the problems go away for a day or so. Log sample below:

Re: Z-Wave Dimmers Activating Without Reason

Unfortunately, I don't have much to suggest on this one. Definitely looks like the module is self-activating since there are no outbound Z-Wave commands from Indigo before it occurs. Try excluding and re-including them (then re-syncing them in Indigo). That normally acts as a factory reset for the module which might help.

Which brand/model dimmer is this?
