What is the difference between the Xiaomi wxkg11LM and wxkg12LM?
This one generates a button press when you shake it, which gives a total of 4 events: single-click, double click, hold and shake
The other one has everything except shake

I use the Samsung button for a panic button with no issues at all. One press and the sirens go off and 2 presses shut the alarms if i pressed the button inadvertently. I've used the button in this capacity for almost a year and the battery is now showing 87%.

There is a good discussion to be had for what safety devices should be incorporated into HE in general. The consensus at least early on in these forums was HE should NOT be used for critical safety or control devices... I think it's pretty clear by doing something like this you are accepting a certain level of increased risk.
Having said that I have a bunch of the Samsung buttons and they work great. They seem much more reliable on my system than the Lightify quad buttons I tested. Not planning on using any of them for panic buttons though.

interesting ... and that's even after multiple days of inactivity?
They're cheap enough, guess it can't hurt to try it and see.
I agree with this, and think that's the fundamental question to be addressed before saying that any given device is reliable or not for a given purpose.
For example, I would never ever depend on any Hubitat based solution to be the primary notifier of a smoke/CO situation. But in addition to independent alarms, yes.
OP wasn't specific about the definition of panic here. For my use, it is primarily a thing to happen when something goes bump in the night.

Iāve been using one of these as a panic button at our office. It shuts off our sliding glass door, sends everyone in the office a notification, and sounds an alarm.
It works a little too well. A coworker was fidgeting and kept pressing it. We got somewhere around 30 notifications, and he lost his button privileges that day lol.

So I work in security. I'm paid to be paranoid, and I've done multiple engagements to gain access to buildings. I once got into a bank vault unescorted during business hours.
In your home, you are unlikely to run into people like me that have the technical expertise to bypass your security controls. Unless you are super rich or have some sort of of other strong motivating factors for someone to rob you. No one is going to be using jammers to steal your TV. They will go to the neighbor instead who doesn't have cams or security system signs.
That said, it doesn't take much to jam wireless systems. I have jammers that work across multiple frequency ranges. And I have used them when breaking into facilities. This was 10+ years ago, but the equipment still works, and others can buy it today.
I've used the same equipment to find vulnerabilities in my own home as well, and to remediate them.
So in general, anything wireless is vulnerable. Cell, wifi, zwave, zigbee, caddx, etc. Caddx and Honeywell wireless less so because the proper equipment is hard to get or build, and relay type wireless equipment also for alerting because the frequency is almost impossible to determine for an attacker.
But, bottom line, if you have enough visible deterrents, a bad guy will move on unless there is something that he knows that provides enough motivation to put in the effort on your house or business.
The best deterrent... A big scary dog. My German shepherd looks like he will go through the glass on the front door. And if he's outside, I don't get my deliveries.

i recommand Xiaomi WXKG01LM Zigbee. Support 5 push and hold! Available on gearbest.com for 14,27$ Canadian currently 11 mai 2020. It work 100% of the time. Driver. Battery will drain slower than Samsung button because it only report when you use it. Samsung Button report temperature so it communicate more often. Normal.
Samsung GP-U999SJVLEDA Smart Button Zigbee, i have 2 of them and do not want to use them anymore. Work on the first press but battery drain to fast (2 year in production and a lot of battery). They support double tap and hold. Report every 0,5c Temperature change
I have a couple of these... They are decent and the 5 push and Hold is nice... but I generally find them flakey.
They don't always stay on the network... sometimes take some time to wake. And I find the multiple push and the hold is inconsistent.. By which I mean, sometimes my single push is received as a hold, and vice versa. Sometimes my 4 taps only register 2 or 3, and the wrong actions occured. I have tried tapping faster and slower and the same inconsistent behavior occurs either way. I have also had it trigger when I place something down beside it, or if it gets nudged (not pushed from teh top) ... I leave it on my night stand, and I have set a glass of water down and it triggers a push.
But they are cheap, they connected easily and are more versatile than the Samsung with the extra pushes.
As for battery... I've only changed my Samsung batteries once in a little over a year... they are far from battery hogs in my book... They also report out an accurate Battery level, where Xiaomi does not. Finally the magnet built in is a nice perk.

Do you use it alone with HE or are you using the Xiaomi hub too?
Thanks,

Direct to HE.

There was a firmware update for the Samsung buttons not long after they were released. I canāt remember if it helped with battery drain or not. I have 5 of them and have to replace the batteries about every 6 months. They seem to drain faster in areas where the temperature fluctuates more, but they are very good at temp reporting.
@Ken_Fraleigh firmware update, you are right
when i receive them i had firmware version : 0x0000000B
currently they are at firmware Version: 0x00000011 last update 13 july 2019 using my SmartThing Hub.
Every sensor will drain battery faster when the temp fluctuate because they will report every change. Each change = battery usage

Do you have to have a Smartthings hub to update Samsung devices? Any other way??
I recommend the Aeotec Doorbell 6.
The button is paired with device so it's fast and works without the hub. It also has a built-in battery so it works without power, but it usually only lasts 3-6 hours.
You can also use it for other things like playing chimes and/or triggering the siren from the hub.
The biggest complaint being reported is that it occasionally has false battery reports that causes the LED to pulse. If you wait about 30 minutes then you can usually tap refresh or push the physical button to fix it, but if you do nothing it will usually fix itself after about 12 hours.
This issue seems to only happen to some users and the fixes doesn't work for all the users having that issue so they have to re-seat the batteries. One using having this issue reported that tightening the button cover completely solved the problem.
I've also seen a few users report that it's not loud enough, but most Hubitat and SmartThings users seem to be happy with it.
The Amazon reviews aren't great, but the built-in Hubitat driver works around most of the problems being reported in the reviews.
Update:
I missed the part about pushing it again to disarm it.
I can't remember if pushing the button while the doorbell is playing will make it send another report, but if it does then you can use rule machine to turn it off if the button is pushed while it's on...
@YapFlapper With a SmartThings hub it's easy because it do it automatically. Just have to wait maybe 60 minutes after forcing the firmware update.
I didn't try to find the firmware file to do it with any other way.
There is a firmware update just released with the latest SmartThings beta that updates to 0x00000014. It also updates ST motion, moisture, and contact sensors (latest generation). I donāt know what is fixed or changed though.
I'm really surprised this isn't integrated into the Hubitat Safety Monitor. All it would require is to allow a button to sound a smart siren
Manual method works too...
