Have you already got garage door working on SmartThings in past? Or you just haven't gotten around to it? You mentioned "was going to use" so I was wondering about this.
Two things you want to keep in mind if you haven't set one up yet is one that you probably need to get a tilt sensor so the hub know what state that garage door is in either open or shut state.
Second you will need to check to see your garage opener is a newer model that use a security wall button.
If it a newer model with a security wall button then you are not going to be able just closed contact on the garage opener's terminal to open or shut the garage door. You will need a security module to send a signal to open and shut.
There is a lot of confusion in terms of naming power supplies vs chargers but what we mean here is not to use laptop or tablet chargers (I think also iPhone chargers have the same issue) because most of them will not activate without having enough load (like a fairly large battery) on the other side. This is something obvious to a tech engineer but not to most of us users who treat a USB power supply / charger as all equal. We found out the hard way that even USB C cables are not all created equal. So initially we thought, let's do USB C, everyone has one from their phone but it turns out we need to be a bit more specific. We'll be including more guidance and disclaimers about the power supply in the box as well going forward.
It will have 1.02 firmware which is now available as an OTA file. Here is the change log for the device with all updates introduced so far.
We highly recommend purchasing the cable online given the situation. A simple USB C cable (something like this for example), not branded for any particular electronics brand will be just fine.
I use a Sylvania zigbee outlet connected to a 12v wall wart connected to the cheapest relay I could find - the relay connects to my gate's pushbutton inputs using cheap speaker cable.
A two pack of the relays cost me $7 on Amazon ( HiLetgo 2pcs DC 12V 2 Channel Relay Module) while the outlet cost ~$16, and the wall wart was 4 for 12 bucks or something that I bought years ago.
I used to have this same setup but with a zwave switch, but zwave range and response time has been wonky for me .
I'm a big fan of Anker cables. Great cables and great customer service. Had a cable from them "die" after only a few weeks, they sent a replacement. Next one died after 2 weeks, this time they sent me the next "model" up instead. I get an email a couple of weeks later saying they've pulled that product and aren't selling it anymore and thanking me for helping them out by reporting my troubles. The kind of thing you'd expect from a big-ticket purchase like a car or something. Great company.
But any cable that supports "quick charge" or "fast charge" should be robust enough and have large enough gauge wires to power the device we've been discussing.
Yes, you can power the module by 12-24 V AC / DC (never use these terminals and USB power together though!) but I don't think standard openers actually have an output for 12-24 V.
I have powered other low amp draw devices off those contacts in the past .....
Edit:
BTW, I should mention that my garage door opener is a 2005 AccessMaster (builder's series from Liftmaster), and I know that other Chamberlain and Liftmaster openers have similar contacts available (except they're push contacts and not screw terminals).
One thing to remember is this is not a constant power supply. The voltage fluctuates and in the moment you press the wall switch, it disappears altogether which is not ideal if you're using the ZEN16 as part of your mesh. So while possible, we wouldn't recommend this solution.
Thanks for this! I've never really thought much about Garage Door openers til now.
Sucks cause my garage has a high ceiling. I just moved here 2 years ago but they just routed an extension core from ceiling outlet. So i have to put a splitter at the end of it. So bit it.
Is there a reason why I can't use a standard 1A 5v Apple iPhone plug? I just received my Zooz today and I'm excited to wire it up and get things working.
i know someone from zooz is listening here. i have one of these relays and it doesnt work correctly.
was working and after reboot of hub doesnt work unless i climb up the latter and reboot it..
"It will not answer to repair requests and itself is not initing a repair when there are two good 3 good repeaters right in the garage with it that are woorking find..
