Z-Wave compatible devices with Dry Contact Out

Hi,

I’m looking for a Z-Wave compatible device that has a dry-contact out.
I don’t want to use an extra relay for this.

Any idea on Homey-compatible devices ?

Thanks

Fibaro single or dual relay switch. Just google that.

It has one (or two) integrated relays. I use it in many applications where dry contact is required. Like switching my 24VAC irrigation solenoid. And more.

The Qubino single relay also has a potential free contact:

Everspring AN179

Thanks for the input. The Qubino has a better price I think, at least when I want one contact.
Anything that does more than 2 outputs in one module?

I have an input module on another system with 4 contacts.
If I can use 2 Fibaro Dual Relay Switches I have 16 addresses, when I use them binary.

@danone
Can you give me an idea how to wire this? The examples I see in the manual (FGS-222, right?) are all in case you need power.

Thanks again

I am not aware of any relay z-wave modules with more than 2 contacts. I have some use for a couple, thought.

You need to power the unit from the main (110 to 240V AC). Live on L and neutral on N.

Then just apply any voltage you want to switch on IN. That can be AC or DC. Whatever you feed on IN, you get out on Q1 and Q2 when switched on either via hardware (applying mains power to S1 and S2) or via software (Homey)

Hope this helps!

Fibaro RGBW controler if you need 12 - 24 V normaly for PWM but probaby useful on 0% and 100%

Hi,

It’s been a while… The location where I want to use this has a USB port (Pellet Stove, USB port for updating firmware). I checked this port, and I can draw power from it, so… since I don’t need to have power on the contacts, a relay powered by 5v would be great.

Any ideas on that ?

Thanks

Maybe you can use HomeyDuino App and an EPS32 device? (not z-wave).

For Z-wave there is a Z-UNO but no Homey App yet, https://z-uno.z-wave.me/shield/
maybe @robertklep, the Shelly specialist, can fix something for this?

Otherwise, if The USB port is powerful enough, you could use a boost converter to get 12 volts from 5 volts and so be able to use a 12 Volts device .


can also be an alternative, probably you need to change the firmware into Tasmota.
