#Looking for a Z-wave device that can read digital signals (~5vdc)

I'm trying to find something like a one of the modules that zooz makes that would allow me to read 2 separate digital signals. If I have to, I can read them as analog values and do the binary/digital conversion in the automation. Ideally, this would be a 5-12vac powered device that can measure 2+ digital inputs. Sadly zooz doesn't have an exact match for my needs and they're my go-to brand. The ZEN17 is close but I'd need to create an adapter circuit to switch the 12vac signals the ZEN17 expects with my binary 5vdc signals. I wonder if an optocoupler could handle this?

The closest I've found is the Fibaro Universal Binary Sensor - it needs 9vdc for power which I don't have available on the device I'm planning to attach this to:

Anyone know of a z-wave device that can read digital inputs?

Connect with z-wave technology.

230V AC is also not an option I presume? Shelly has the i4

That’s correct

I4 is confusing me. It describes itself as handling 4 digital inputs, but the wiring diagram on the case sure makes it look like it’s all mains. Also not z-wave.
I can’t do WiFi, but I could consider an esphome device with Ethernet connection. Hmm… still prefer z-wave

There is definitely a Z-Wave version

Hi,

I am using the Zooz zen 17 and it is working great. An optocoupler would definitively work as well as a 5v micro relay ( simpler if you have enough current to drive it) along with the zen 17 dry input. Alternatively a transistor could also be used.
I know that zooz spec their input to be 12-24v but in practice they are much more sensitive than that.

Good luck
