Can I combine relay modules for more poles?

I'm wondering what it would take to have an order switcher controlled by a relay.

The obvious answer to me would be to just hook up two relay modules to the same switch. I could probably mess with that. I just don’t know if I’ll have synchronization or debouncing issues, etc…

I’ll report back here if I test this.

I *hink* you may be able to use the CTRL pads as well? @Robert ???

Maybe? Not sure I can do that without reprogramming. The only use I’ve seen for those pads is putting multiple relays on the same control bus to ensure all other switches on the buss switch off if you enable one.

Someone else here has used two modules with one switch, it's definitely doable. I want to say they used a couple of diodes to prevent false triggers but I can't recall off the top of my head.

The CTRL line wouldn't be any help without a code change.

I do have a design for a relay based order switcher... that'd be a cleaner option for sure. I'll try to get some in my next order.
