I’m new to SmartThings and not super technically inclined and I have a few things I need help with. First can someone explain edge drivers and how to use them? Secondly I’m trying to set up my Yale assure lock 2 to Auto Unlock based on geo fencing but the couple issues I have are ST geofence not even work but the other issue I have is the radius being too large because I live at an apartment complex that I also work at so the radius is too large and if it did actually work it would unlock when I’m just driving by (also might not be working because radius is too large and it’s not reading that I’ve left) but can someone recommend a device or a work around that would allow me to fine tune the radius so it only unlocks when I’m a few feet from my door. Thanks in advance
Welcome! 
Here’s the community introduction to edge Drivers. The first section should tell you most of what you need to know.
FAQ: I have no idea what Edge is. Is that a new developer tool? (2022)
As far as limiting Geolocation to a small area, as you’ve noticed, the standard method doesn’t work very well for people in apartments. Or for some other use cases, such as my own. I am a wheelchair user, and I don’t want my door to unlock until I am at the end of the wheelchair ramp. Not when I’m still on the bus halfway down the block and waiting for the bus driver to unload me. 
There are some different workarounds available that depend on the type of phone you have (iOS or android), and the specific Wi-Fi router that you have. The goal being not to use GPS, but to use something where you can narrow the range much more. I’ll post a link to a thread about that later today.
And welcome again! Glad you found the forum: it’s a very creative and helpful community.
in future, it will help everybody if you limit your new threads to one topic. Also, the more specific, your thread title the more answers you will probably get. Just something to keep in mind.
Thank you for your response, the link about edge drivers was very helpful although I’m still having trouble finding an edge driver for my lock. @RBoy potentially has a driver that will work for it but when I look at the list of model numbers it works with mine (YRD420) is not listed although YRDxxx is listed but I don’t want to pay $10 just to find out it doesn’t work.
For the geofence issue I’m using an iPhone with an eero 6 router and extender. I’ve read some threads that mentioned using some type of presence sensor or maybe they called it an arrival sensor to be able to narrow the geofence radius but now I can’t find the thread that was talking about it. Also I’m still trying to figure out how all this works including this community page. Thanks again for the response and the information
OK, if you have an iPhone and an eero router That gives you two different possible options for setting a narrower Geo zone.
First, you can use ibeacons. This should definitely work (I use it in my own home), but it does require buying the additional ibeacon device and it may require having an always on receiving station device (an old iPhone or old iPad plugged in at home) Depending on your exact use case. And you have to buy two additional third-party apps. So this one adds additional dollar cost, but is very reliable, highly customizable, and works quite well. I have mine set to a detection zone of about 10 m, which is about the length of the wheelchair ramp to my front door, for example. Here’s that FAQ
FAQ: IBeacon Short FAQ (2024) (US AND UK)
Alternatively, with the eero router, you should be able to set it up so that when your Wi-Fi router detects that a specific device has joined the network, typically your phone, you can then turn on a virtual switch and use that as your presence indicator. This method requires more technical expertise, but it’s definitely doable. The primary issue is that the detection zone may still be too big for your needs, it just depends on how far away you get a Wi-Fi signal from your apartment.
I know @TAustin has a thread about that, but I don’t remember exactly which one. 
If you have the Zwave model you might check Z-Wave Lock PH I know it supports some Yale devices, and if it doesn’t, you could post in the forum and ask the developer to add the fingerprints for your lock.
This works with the YRD420 and it supports the new module features such as battery saver
Question - do you have the zwave module or wifi module?
A post was split to a new topic: Yale Assure 2: Best AutoUnlock Protocol? Other Options?
I have the z wave module. Thanks for letting me know that it works with my model. So I would just go to link and on your website I would pay for it and then enroll and then go to ST app and change the driver and that’s all? Again thanks for the reply everyone in this community has been very helpful and I really appreciate it!
Yep that’s it. The YRD420 has two models the zw2 and zw3 (500 series and 700 series zwave modules), the driver supports both models.
Awesome thanks again!
I tried using that already but after I accepted the invitation and enrolled I went to available drivers and the one for the lock ph says it’s for Schlage so I didn’t know if it would work with my Yale lock
I think im leaning towards ibeacons, actually the post I mentioned in my comment above that I saw someone talking about arrival sensors and stuff that I said I couldn’t find anymore was actually your comment on a different thread made way back in March of 2016 lol but anyways so to have the Auto Unlock work for both me and my girlfriend would I need two separate ibeacons? Or I also read that a lot of people used Alexa geofence and it works better than ST so since she doesn’t have the issue of working at the same apartments she lives at I was thinking maybe for I use an ibeacons for me and then for her maybe I try using Alexa’s geofence since she comes home the same way every time and doesn’t drive around the apartments like I have to. But for the ibeacons I was kinda leaning towards a usb powered one so I wouldn’t have to charge it. But I was also curious about using geofence with a precondition like some type of motion sensor or something that only unlocks with that combined with me crossing the geofence border. I’m having a hard time with this stuff honestly because of my lack of knowledge but so far this community has been a godsend
Alexa presence works well for a lot of people with the factor that you mentioned: much wider detection zone.
As far as the IBeacon, you only need one of them if the IBeacon stays at home and you put the receiving station app on each of your phones.
For example the receiving station app that I recommend, Geofency, is used by trucking companies to check the trucks in when they arrive at a specific lot. There’s one Ibeacon at the lot, and each truck driver is automatically checked in on their phone as they arrive. So it’s the same idea with multiple members of the household. As each one arrives, their phone recognizes the one I beacon that stays home and that triggers whatever event you want to have happen next. Probably a smartthings routine. Note that it can even be a different routine for each person if you want. It’s up to you. Because you each have a copy of the receiving station app on your phone, you can set it up to be either different or the same as the other phone.
Or again, you could use the IBeacon for your phone and Alexa presence for hers.
As far as a pre-condition, you could use that, but the motion sensor is going to be activated by any motion in that area, so your door might still unlock before you get there if someone is walking past. So again that’s up to you.
We use Alexa for geofencing for multiple locations and it’s quite reliable. Smallest perimeter you can set is 492 ft.
Yeah, that’s 150 meters.
And its radius, not perimeter.
So pretty sure that’s the same size as smartthings’ geopresence, which is too big for the OP’s purposes.
In contrast, an I beacon offers three distances: immediate (about half a meter), near (about 3 m) and distant. So for use cases like not wanting your door to unlock until you’re close enough to see it, the near distance is usually pretty good.
I really appreciate all your help. I think if the ibeacon is accurate enough to reliably unlock your door when you get to your ramp then I think it’ll be perfect for me. I’m also trying to figure out virtual switches now. I had bought a fan switch and a dimmer switch and a smart outlet back when I had first got an Alexa speaker before I planned on going with ST and all 3 are cync by ge that is non ST compatible so I read that virtual switches or sensors might able to control it from ST and I installed vedge creator v2.94 and then I read that for Alexa the Alexa multi-trigger is better for Alexa but when I started to try figure it out it seems like it would use Alexa to run a SmartThings device and not the other way around. Am I missing something?
Oh and sorry I forgot to ask also about the usb powered ibeacon would I be able plug it directly into a usb charger box and just leave it plugged in the outlet or would I have to plug it into a device like a conouter? Also can you recommend me a brand of usb powered ibeacon please
It can plug into any phone charger that matches its specs. It just needs power, not a computer.
Blue Charm has a USB powered ibeacon with a decent configuration app.

Manufacturer quick start guide:
Here’s the faq:
FAQ: Can I trigger an Echo Action without Speaking to It?
You create a virtual device in smartthings and then, when you turn that on, it can run a Alexa routine (not a smartthings routine) to turn a device connected to Alexa, but not visible in smartthings, on or off. Like a Cync bulb. Or do anything else that an Alexa routine can do.
Here are the Cync instructions
Cync Product Support Help Center.
That said, at the time of this writing, it’s a one-way integration. If you turn on the Cync device in any other way, including from its own app, SmartThings won’t have any way of knowing about it, so the status in the smartthings app can get out of synch.
So people more commonly use this method for either smart plugs or devices like robot vacuums, where they just need to turn it on or off. Bulbs get trickier, because there are so many ways to start them and you usually want to track the state.
Cync intends to put out new models that will work with matter, in which case, those will be able to work directly with smartthings as well, but they are not, as of the time of this writing, going to update the older devices. 
As Jd said you need to create a virtual device in SmartThings.
You would not want to use Alexa multi-trigger in your case. Instead, use the regular Alexa switch from the Vedge creator. After the device is created, go into the settings and select separate contact. Alexa can see the separate contact sensor open and close as you turn on and off the virtual switch. Then, you can set up Alexa routines based on the contact sensor being open or closed.
