Overly sensitive momentary contact?

Hey, all -- I'm hoping this is a common issue: I have two steam showers running Mr. Steam's HomeWizard modules which turn on via a momentary contact closure from my EA-5. At first, they were fine, but lately, they've started occasionally triggering on their own, either (seemingly) randomly or when switching big electrical loads in the house. In case it's relevant, my neighborhood is also under construction, and I sometimes notice my LED lights (which are sensitive) giving a little flicker, which I assume is due to activity on the lines/infrastructure. As a final detail, the leads long but shielded wire.

Is there some type of a filter/resister I might put on the leads to soften the sensors response? Would switching to a Z2IO closer to the sensors help (due to the long leads potentially pulse-energizing)? Is this something a power conditioner placed somewhere solves for? Of course, hoping there are other, better ideas I haven't thought of as well.

Thanks in advance!

Given I see 100+ views but no replies, figured I'd try something and report back. Going to install ferrite filters (those clip-on magnet things) on the lines, as I think they're long enough to induce serious EMI, which could be tripping the closures. If that doesn't work, next step is installing optoisolators...
