Reddit reviews GoControl Z-Wave Isolated Contact Fixture Module - FS20Z-1

You need a dry-contact z-wave switch like one of these:

• https://www.amazon.com/Remotec-Zwave-Contact-Fixture-Module/dp/B00913ATFI/
  
• https://www.amazon.com/GoControl-Z-Wave-Isolated-Contact-Fixture/dp/B00ER6MH22/
  
  The switches would be powered at 110V AC, with the 24V wiring connected to the dry/isolated contact side.

That particular box is a low/high voltage box. The left side is open for low voltage wiring and the right side is for high voltage wiring (hence why it is enclosed. Mr_Norwall is correct... it is probably just a control line for an ignition system in the fireplace 'controller'. The green would be the ground (so it doesn't float) and the red/white would be the line to start the fireplace.


Another solution you might want to check out is an in-wall module or a dry-contact relay. Such examples are:

Some dry contact modules will still require 120v to be added though. The Aeon Labs, for instance, just runs on a coin cell I think.

edit: adding product links

Save yourself some money and get this relay. You'll notice that the "frequently bought" also has a tilt sensor to be used to determine if the garage door is open.

This is the setup I use and it has been flawless so far. I use it with Amazon Echo and have to say "turn on garage" but that's not a big deal to me.

Dry contact relay. Like this: https://www.amazon.com/GoControl-Z-Wave-Isolated-Contact-Fixture/dp/B00ER6MH22/ref=sr_1_1?ie=UTF8&qid=1480161156&sr=8-1&keywords=zwave+relay

Yep, that one works. I have one of those on my fireplace and can use Google Home via Emulated Hue to turn it on/off.

Really any Z-wave relay would work. On my garage door I use this one:

https://www.amazon.com/GoControl-Z-Wave-Isolated-Contact-Fixture/dp/B00ER6MH22.

Then you also need a garage door tilt sensor like one of these (I've used both with no problems, one for a mailbox and the other for the garage door):

https://www.amazon.com/Z-wave-Plated-Reliability-Garage-TILT-ZWAVE2-5-ECO/dp/B01MRZB0NT
https://www.monoprice.com/product?p_id=11987

I haven't looked to see if there's a better workaround, but since a garage door needs just a momentary pulse from the relay to run, you have to turn the relay back off, which I did with a Home Assistant script:

https://github.com/hunterstee/Home-Assistant/blob/master/script.yaml

This means that to open or close the garage door via Alexa/Google Home though, you have to say "Alexa, turn on the garage door". Telling it to turn off won't actually close the garage door because the relay has to be turned on to cycle the door.

EDIT: This is what my setup looks like in Home Assistant: https://i.imgur.com/G5FATEi.png

They make a controllable set of contacts that you could connect and then stick a motion sensor up in the hood. Set it so that when motion is detected it turns on and then if no motion for 20 minutes it shuts off.


I had the same issue but with the light in the range, so I took the range hood apart and mounted a GE link bulb in it. They are sized for a little 40w max bulb. I also had to defeat the built in dimmer.

The only hustle is you have to use your phone or Alexa to turn it on/off. Otherwise you need to cycle the power switch.







GoControl Z-Wave Isolated Contact Fixture Module - FS20Z-1 https://www.amazon.com/dp/B00ER6MH22/ref=cm_sw_r_cp_awd_Idh-wbY297JD0

For mine we bought a house that had one installed but it had one of those doorbell style buttons on the wall using a simple 2 wire coniguration so I added this and it has worked perfectly. My point being if you intend to have a wall button then you could do something simple like this and get any brand that you like giving you more options.

I use one of these for each garage door lift, and a cheap zigbee open/close sensor to automate my garage doors based on mine and my wife's location, and time of day. Happy to share my code if you think it'd be helpful.

This might work: GoControl Z-Wave Isolated Contact Fixture Module - FS20Z-1 https://www.amazon.com/dp/B00ER6MH22/ref=cm_sw_r_cp_awd_WbLNwbTX866Z0

A mimolite would also likely work.

The remotec module has the external switch input, so that's what made it so easy. You can keep your switch on the wall working as intended.

The mimolite has an input, but I'm not sure if it would work the same as the remotec.

So you will need to remove the remote module that's currently installed and replace it with just a Zwave relay.

Edit - something like this

There aren't really market z-wave products that run on low-volt. Assuming you have a gas fireplace with thermopile switch, your best bet is this dry-contact switch:

https://www.amazon.com/GoControl-Z-Wave-Isolated-Contact-Fixture/dp/B00ER6MH22/ref=sr_1_2?ie=UTF8&qid=1482810232&sr=8-2&keywords=dry+contact+switch

You would either plug it into an outlet or junction box to power the z-wave connectivity and connect the isolated contact sides to the same circuit your thermopile is on to turn on the fireplace. There was a Wink users group post about it a month ago or so, but I can't seem to find it. I'm the one inquiring about how to connect it, so it was news to me at the time.

I suspect that's part of it, and it's definitely worth it to me. The signal input is very flexible. I suspect the other part is Z-wave is a proprietary protocol and requires license. Finally, it's not exactly a high-volume device.

I think the mimolite is way more polished than other options. I wish their marketing would have more examples highlighting the possibilities. It can trigger on power loss, it can trigger when voltage is within a certain configurable range, or outside of a certain configurable range, it can use the signal to toggle the relay locally, it can use the signal to control other devices, it can be polled for signal or report on a configurable timed basis.

I have 2 of these, one for my garage door ( http://imgur.com/a/db2tQ ) and one for my doorbell ( http://imgur.com/a/fzUE3 )

Sure, this could have also done this with an AVR and an esp8266 for some awesome franken-MQTT device, but until I can set up a bench, this is much easier and faster to set up... and much easier to recommend.

If you just need a z-wave dry contact relay, there are other less pricey options. These would be great for something like low voltage zoned lighting, a fireplace, or electronic shut-off valve.

http://www.amazon.com/Remotec-Zwave-Contact-Fixture-Module/dp/B00913ATFI/

An important feature these options lack is a mode for momentary contact, which is handy when interfacing with buttons like a garage door, electric latch, or gate controller.

I would focus more on the smart switch aspect and less on the monitoring aspect. You could get an energy monitor that is capable of observing total consumption of your home. Look at Sense or Aeotec, they both have products for that. I think they can both slowly begin to identify individual devices, their consumption, and alert you when they're on or if they've been on for longer than a predefined amount of time.

There's a broader range of products that are simple z-wave devices and don't focus on energy monitoring. However, 20 Amp zwave deives are a bit hard to find. Aeotec has one for up to 220v and 40amps, which may work.

Go Control has a similar product for 20 Amp 120 circuits.

As an alternative there is this module.

I was going back and forth deciding to get the Remotec or this GoControl model to control my garage door. Decided on the GoControl and it has been working great for a couple of months now.

I followed these instructions https://imgur.com/a/2gJxj using a GoControl FS20Z-1 z-wave dry contact switch bought on Amazon. I had a small change in the setup where my fireplace model differed from the writeup https://imgur.com/kwFJ8j1 I then paired it with Wink 2 hub and IFTTT and it worked great. But I've switched hubs to Hubitat Elevation hub which ties directly to Google Assistant. I love it. I have retained the original switch on the wall, AND have app and voice control over the fireplace.

Watch out, you're going to get the boo birds in a few posts telling you that you should NEVER automate something that can burn your house down. For that reason I have a rule in my hub to automatically turn the fireplace off after 30 minutes no matter what. This way I also don't let my wife run up the gas bill :).

I just did exactly this. https://www.amazon.com/gp/aw/d/B00ER6MH22/ref=ya_aw_od_pi?ie=UTF8&psc=1

Works like a charm. Use a old power supply cord and plugged in under the fireplace.

Not sure how large a motor your running, but this may be able to do what your looking for. I think it should pair as a generic zwave switch...

I use a zwave dry contact relay for mine. This one: https://www.amazon.com/gp/aw/d/B00ER6MH22/ref=mp_s_a_1_1?ie=UTF8&qid=1483897250&sr=8-1&pi=AC_SX236_SY340_FMwebp_QL65&keywords=zwave+relay&dpPl=1&dpID=31WTIqBdTIL&ref=plSrch

I'm wondering why is it still so expensive when ZWAVE device with same features (dry contact relay) is $37 regular price

https://www.amazon.com/gp/product/B00ER6MH22/ref=ox_sc_sfl_title_3?ie=UTF8&psc=1&smid=ATVPDKIKX0DER

dang, unfortunately i only got a this relay
http://www.amazon.com/GoControl-Z-Wave-Isolated-Contact-Fixture/dp/B00ER6MH22

and it doesn't have the functionality to be a momentary contact switch.

I assumed wink had the functionality to at least mimic this with software, since smart things does.

I figured another use for the dry contact - for my gas fireplace. BTW...there are other z-wave contacts available on amazon: http://www.amazon.com/GoControl-Z-Wave-Isolated-Contact-Fixture/dp/B00ER6MH22/ref=sr_1_sc_1?ie=UTF8&qid=1453504530&sr=8-1-spell&keywords=Remotec+Z-Wave+Dry+Contact

For what it's worth, here's the one I bought;

Search for "dry contact" + preferred connection technology.

e.g. zwave dry contact

you'll want to use a dry-contact relay to control that valve.
You can use the one you linked, but you will also need a 12v power supply. Here is a Z-Wave one, no programming required. It provides a simple on-off switch.

Not sure on the humidity/water sensor

You need one of these relays.

I have the first one and it won't fit in a gang box, so you might want to try #2.

I wish there was a "z-wave finger" that just pushed a button, but mounting that would be difficult.

So I guess I'm still not sure what you are actually after. Just a waterproof wifi plug? If so I'm not aware of such a thing.

That being said, what about something like this? https://smile.amazon.com/GoControl-Z-Wave-Isolated-Contact-Fixture/dp/B00ER6MH22

Or maybe this: https://smile.amazon.com/GE-Wireless-Lighting-Control-Outdoor/dp/B0013V8K3O/

depending on your hub - I have smartthings
you should have several choices
you'll need to figure the max current draw of the fan or the HP
then install the appropriate switch

easiest would be the wall switch and some temp sensors, if it wil handle the load

I have the go control - originally for my old garage door (programmed as a momentary switch) - it will handle 20 amps and is cheap.

GE also has a 40 amp heavy zwave switch - for $150ish

with the smartthings hub you could program time on, time off , on for event, off for event , (event could be window opens , temp specified, etc) and then run time for specific period of time or if temp is satisfied with enough connected things you can control all kinds of things - fan included :)
good luck


direct load good for 20amps

I trigger my millivolt ignition system using a Z-Wave isolated contact relay setup as a switch on my SmartThings hub.

The relay needs 120v AC to power the radio.

SmartThings let’s me control the fireplace from my phone and Google Home (also Alexa compatible). You can also add various remotes or switches that work with the hub.

Correct. The multi-load relay essentially allows the loads to be wirelessly controlled but have no physical control interfaces themselves.

There are single-load relays which are available with and without physical control interfaces:

• Without: Contact Fixture Module
  
• With: Remotec Dry Contact ZFM-80
