Bringing blind to automation with vera3

Hello Folks !

I bought a curtain and it comes with infra-red control…but in your documentation comes instructions and a little cable to integrate to home automation.

my doubt: for this kind of automatin (see picture) what I need to buy to have zwave control in vera3 for this my new curtain ?

thanks !!

please see document in attachment to this post.

Piwtorak,

You need a relay (switch) that can be controlled by Vera. Depending on where you are located in the world, you may be able to buy something off-the-shelf that can do some of this. Some possibilities: Global Caché GC-100; Evolve LFM-20; Fibaro Relay Switch. If those are unavailable or too expensive, you can make your own with a microcontroller and a handful of components.

You’ve got lots of options. You will need to whittle down the choices based on your own technical ability, willingness to spend time or money, and physical constraints such as space or proximity to power.

Hello Futzle,
I have one evolve lfm-20

can you help me with the connections (what wire goes in what wire ?)

I have a doubt: the motor of my curtain is 12v, evolve lfm-20 will delivery 120v, correct ? how can I adjust this voltage ?

thanks a lot…

The LFM-20 device itself is powered by 120V. All it does is connect one blue wire to the other, if activated, as if there were a mechanical switch there.

please a little more of patience…

:slight_smile:

you want say me, in the blue wires do not have current ? only a kind of signal ?

thanks !

Hi Piwtorak,

Having never seen an LFM-20 (they are not available in my country) I can only repeat what I have Googled. Which you could do yourself just as easily.

If you do not want to commit the time needed to learn the basic electronics that you’d need to do this task, get someone in to do it for you. Personally, I do not have the stamina to teach you one forum post at a time.

I hope not to have offended you with my insistence. your posts help me a lot.

Thanks !

but I hope find someone what have do it that with evolve lfm-20…

I agree with @futzle (and @garrettwp previously): it would be nice to know what you already know, have done or researched yourself.

Are you familiar with relays, or have you read, say, the wikipedia page on them?
You already owned the LFM20; what did you intend to use it for / what was your expectation?
You’re asking about 120V / current; did you put a meter on it to see if you could find the answer yourself?
Did you find a post, but had an additional question / need some more clarification?

It really is just a blue wire that is either connected to, or disconnected from, the other blue wire. As if you had a blue wire, a regular switch and another blue wire. Or just two blue wires that you connect/disconnect yourself.

Quick search got me this.

Hello !

you guys are with all reason, maybe I’m a little anxious to make things work due to my high investment in zwave and micasaverde equipments. (including a lot of evolve lfm-20 devices)…
sorry if bother, I’ll look further study the forum.
I’m in that disposition can help to this community.
Hugs.

Exactly; you’ve stated previously you’re doing a big project, so we’re keen on getting you to learn how it all works through studying and ‘playing’, rather than just saying connect this wire here, and that wire there. You’ll have to maintain this big project in the future!

Great !

is good have peoples like you helping me and anothers like Garret, Futzle, etc.

I think is a lot to do with zwave we all love.

go Ahead now !

bye !

Looking at your posted picture, these are the wires that operate your window covering motor:

Black = Up
Yellow = Down
Red = Common

As @oTi said, the Evolve LFM-20 is just a switch (an electronic Z-Wave triggered Switch) that doesn’t switch any load (high voltage) but triggers the contact closure wires on your motor. So if you hook up the LFM-20 or any relay to the Black and Red wires, when it is activated the motor will go Up (or one direction), while hooking it up to the Yellow and Red wires and once activated will operate you motor down (or in the other direction). Hook up your motor to power and touch either the Black or Yellow wires to the Common-Red and you’ll see what I mean. By you touching the wires together you are acting like the LFM-20. Now you just need to figure out what wires on the LFM-20 will give you that contact (it sounds like it is the two blue wires, but I haven’t looked into it).

Sorry if this is obvious info, but I thought it would help you get started.

Fantastic !!!

for a people with my level is perfect…

thanks for expend your time, soon I will post the results…

Hello !

advantage that you mention Evolve LFM-20…

has someone installed it on vera3 ? how it appears on dashboard ?? like an on/off or 3 buttons (1 for each contact) ???
How I turn to contact in output A or B ??

if can put a picture will be good.

Thanks !

It shows up as a normal on / off switch.

@Piwtorak,
Yep, as discussed before, it’s a switch, connecting the 2 blue wires when on.

Pics (of the physical device), controlling a garage door in this case. (The blue wires are connected to the white wires, in parallel to a physical button (not shown) to open the garage door. Think of the LFM20 as an ‘automated button’.)

Ok, then I will need 2 LFM-20 to do my curtain up and down correct ?

once I have only 2 blue wires…

thanks…I’m almost there !

Oti@,

I’m stopped with my instalation only for one doubt.
can you help me ?

that is:

using evolve lfm-20 for curtains I will need 2 pieces, one for up and one for down ???

with this I will buy another and conclude my instalation.

but I think must exists one unique device what realize this job withount need of set up 2 evolve lfm-20.

thanks !!!

Yes you would need two. As you have already found out, Global Cache products offer multiple contact closures in one product, so you could also use one of their solutions.
