Recommendation for an EU LR Z-Wave motion sensor for a letter box

2 Upvotes

As per the title, I'm looking for a Z-Wave LR (800?) motion sensor small enough for a letter box.
I tried to pair an Aeotec ZWA045 with my new ZWA-2, but it seems like the European version doesn't have Long Range (still not sure if limited by firmware or if the device is physically different).

Any recommendations are welcome.

Replacing WEMO

6 Upvotes

I’m looking at replacing the WEMO switches I’m running. Appears zwave is the way to go. What are the go to light switches and wall outlets? Some of my light switches are 3 ways.

Also what is a decent hub? I ultimately want to control the setup with an app on my iPhone. I’d also prefer to not be locked down to a proprietary hub as companies discontinue support which is why I’m replacing the WEMOs.

Door/rely sensor in metal mailbox add wire to sensor for external antenna?

6 Upvotes

I have a steel mailbox in a paver column 250 ft from house (no trees). LR Zwave works fine outside of mailbox but not in.

I have a 12v landscape light in said column. So thinking of adding a Zooz DC Relay ZEN58 (12v powered). And wiring a wired magnetic door/widow contact to it. The Zooz relay has an internal spring antenna.

Was thinking of drilling a hole through inside of mailbox and adding the correct freq length (roughly 8" in USA) for the antenna. Snipping of spring antenna and soldering wire to it (probably with a quick connect for removal/replace sensor). I assume that will work. But was curious if anyone had experience before a ruin the sensor.

Any recommendations for a Zwave 700 "repeater/extender"? USA

0 Upvotes

Hi everyone, I think I need a repeater/hub/something between my z stick 7 radio and my zooz water valve. I'm currently seeing -95db but I can't query the device unless I open some doors, right now it shows up as unavailable/dead.

Any recommendations? If it was zigbee it would be easier to get a router in the format of a smart outlet. Something amazon or aliexpress would work.

Much appreciated!!

Update: got a Minoston Plug with Energy Monitoring MP31ZP for $23.99 and a used Ring Range Extender gen2 for $12. Will try both and maybe return the Amazon one. Thanks for the help!

Do the Zooz plugs get old and go bad?

3 Upvotes

I bought a bunch of Zooz 3-5 years ago and 2 of them now go into a red flashing state after turning on simple LED lamps. I'm wondering if the sensitive power monitoring stuff got old and goes bad?

What's the best brand? I bought zooz initially because I thought it was top quality

How to debug occasional dropped RX?

1 Upvotes

I have a Zooz door contact sensor and a tilt sensor that both occasionally miss events. If I look in Statistics in Z-Wave JS UI, I see 1 or 2 dropped RX, out of 40-80 total RX.

How can I debug this and bring it to zero? The missed events can be a major nuisance because automations will think a door was left open when it wasn't, for instance.

I'm using the Zooz USB hub on a USB extension. My house has two floors, but there are quite a lot of Z-wave repeaters. I have 44 total nodes, mostly contact sensors.

Truth be told, I don't clearly understand why there's dropped events at all, with my understanding of Z-wave. All of these sensors have many neighbors. Shouldn't it keep trying to send to all of them before it gives up?

Schlage J-Series lock keeps factory resetting itself

2 Upvotes

Not sure if this is the right place to ask, but maybe someone has seen this before.

I have a Schlage J-Series Lever Lock that worked great for several months. Then, about a month ago, it started beeping.

I found that it somehow factory reset itself. It automatically paired with Z-wave JS UI with a new node ID, which was weird. I still had to re-add my codes and other settings. I also had to replace the entity in Home Assistant.

Has anyone seen something like this before? Does anyone have advice other than spending more than $30 on a smart lock?

Zniffer. Help.

2 Upvotes

I need an idiot’s guide to buying and flashing a usb stick for use with Zniffer. Because apparently I’m the idiot. /s

I’ve been trying to do this for a few months and even purchased what I think is the wrong module etc. frustrated.

I suppose what I need is a link to which usb module to buy, and a second link to the firmware file that needs to be flashed to that usb.

By way of background- I already have simplicity studio installed and up and running with a regular Zooz stick with no issue.

I tried using this link - https://bishopfox.com/blog/set-up-zniffer-for-z-wave

But the instructions take me to a page to purchase a dev kit for $500. Is that really needed to download the Zniffer firmware? Can’t see where to get that firmware.

Thanks all.

Help diagnosing my network. Suddenly only one device works.

1 Upvotes

I have had a z-wave network with about 15 devices running for years. Rock solid. The devices are heterogeneous from various makers. A few crapped out early but the rest are survivors. A few months ago, suddenly all but one are unreachable. The physical switches still work, but they are no longer reachable from the controller. Oddly, just one device is reachable and continues to work fine. And it’s one of the farthest ones. I am at a loss and do not relish redoing every one. Any ideas to try?

Outdoor hose timers?

2 Upvotes

I see some for zigbee but nothing really for zwave. Having been using zwave for a decade, I'm pretty bummed. I really don't want a vulnerable WIFI device on my network or having to go buy a 2nd dongle.

What do you all use to turn on/off a sprinkler/irrigation using zwave? I see 1" ball valve for water mains but that would be a pain to adapt to a hose bib.

Another issue is that I have low water pressure and need a timer valve with no restrictions so my sprinkler gets maximum throw. A manual timer I tried adding cuts my sprinkler throw by 1/4 making it useless.

Is ElCap from Trident IoT a more efficient version of SiLabs Simplicity Studio for Z-Wave IoT systems?

3 Upvotes

Recently found out about ElCap - a CLI based SDK from this IoT start up and was wondering if anyone tried it and their experiences with it? Switching the SoC supplier could cost a lot so it would only make sense if ElCap can really cut operational costs, which seems to be the case but need some assurance.

Is it possible to keep this switch and add a relay behind the wall?

This timer switch is clutch. But when I’m going number two, I was thinking of turning on the fan using google speaker instead of reaching for it while I’m on the john struggling with my hands and legs all paralyzed. What’s a good solution to make it smart but keep the switch? Thanks

Scene concepts

1 Upvotes

I'm not sure if I'm missing something, or if the concept of scenes just has an unfortunate limitation.

Background: my zwave network is made up of a homeseer hub and largely a combination of homeseer and zooz devices.

iiuc, when you use a scene based control the scene gets updated. This sounds obvious, but due to it updating the scene rather than sending some sort of trigger, the same scene is not set twice consecutively. This makes scene control really limited.

Quick example: I have my a light switch set so that 3 taps on the bottom panel scene turns off every light in the house. The issue is that this light switch isn't often used for anything else (the lights in controls are infrequently used), so after using it successfully one night it doesn't work the next. The solution is to turn the light on and off, after which the scene change is sent and properly works.

Am I missing something?

Is there a way to make devices report scenes every time they're set?

What prompts Z-Wave JS UI to change network diagrams?

Thumbnail gallery
5 Upvotes

I occasionally look at my tiny network in Z-Wave JS UI and sometimes the range extender is depicted as a hub and sometimes an extender.

Nothing changes about the devices: location, people proximity, furniture arrangement, doors opened/closed, nearby vehicles, nothing.

Only the weather changes. The controller is on a second floor. The strobe is on a first floor. The sensor is outside the house in a small plastic container about 50 feet (15 meters) from the range extender.

Does the network adapt to changes in signal strengths? Does the network experiment with different configurations? Are the changes random representations?

What prompts Z-Wave JS UI to change network diagrams?

z-wave deadbolt - setup worked, now unavailable

3 Upvotes

just got a z-wave stick and a z-wave deadbolt (kwikset 620). I was able to set up the deadbolt and connect it. Everything worked fine for a few hours, then the deadbolt went unavailable. I can lock and unlock it normally from the lock, but HA cannot see it.

I'm new to z-wave, unsure if there is a simple solution to this. Thanks!
