Webcore Presence by Ady624
Thoughts:
Have you noticed the Webcore app thread with regards to that app being devād to provide a more robust presence scheme?
I also use multifactor presence - along the lines of what you refer to in your other thread - My Phone (ST App) must become present and then my ST physical presence sensor in my car must become present (both after at least 6 minutes of being away) for my house to change to home status and open up the garage door and unlock the door. I wonāt have it doing this without these extra steps.
Sometimes it does fail because the physical presence sensor doesnāt register in time upon arrival and I donāt want to wait for it to do so, so I push the button on minimote to kick start it.
I think the new webcore app has the potential to help solve some of these challengesā¦
No I havenāt but that sounds awesome! I would easily be a happy candidate for such testing. Also could you link that thread for addition to the top post. I feel it might help others 
Also could you present a screenshot of your piston for example, Iām thinking of hopping away from my methods and trying that out instead. Do you have android or apple for your phone? Also what minimote?
I think you found the thread:
Hereās a snippet of the piston I currently useā¦ will use webcore app to enhance this when it comes outā¦
iPhone only for presence here. Presence is not critical for me though, no doors opening or unlocking automatically, but I do use it to enable/disable notifications. I have a ST arrival sensor in a car but have not found it useful enough to justify replacing the battery. It will probably end up in a backpack when kids start school.
The geolocation can wander terribly while Iām home so I combined the SmartThings presence with Host Pinger which runs on an always-on PC to check whether my phone is connected to wifi.
Combining these two works acceptably well for me but since the phone is not always connected to wifi there is a necessary delay before considering a wireless device away (HostPinger handles this). That means with my current setup I cannot have a very accurate departure time since HostPinger waits about 8 minutes before declaring me away.
I think there are better options with Androidās Tasker but Iām eagerly awaiting the webCoRE app!
Right now I am testing out the tasker/sharptools/autolocation method. It works ~ 90% of the time and so far Iāve only had one failure.
Has anyone figured out a way to use Automatic as a presence sensor? I have one in my car and thinking I could use that + iPhone App for a bit more assuranceā¦
Not exactly sure how I could pull it off ā¦ but currently using IFTTT and Stringify to do different actions based on if the car is coming or going (lights, garage, etcā¦)
Soā¦ could I have IFTTT set a virtual āpresence switchā when my Car arrives to āJohnās Homeā or something that I could use as presence?
Sorry for the stream of consciousness ā¦ hanging out having a beer reading forums ā¦ 
Thatās a really good idea. Looks like there is IFTTT support for Automatic and there is webCoRE support for IFTTT so you should be good to go. I wish there was IFTTT support for ZUS as that could also be used as a presence sensor.
Hell, if IFTTT or Stringify had access for my Volvo natively I would not need the Automatic
I havent seen WebCORE supoort for IFTTT ā¦ where is that, perhaps I can remove a round trip from IFTTT->ST->WebCore if I can get a trigger from IFTTT/Stringify direct to WebCore
need to have more 
before I start thinking this through
What operating system is your phone on? Iām finding Iām having issues with the app showing me home. I also find that the ST arrival sensor has a bit of a lag to it as well for showing the car home. What tips/settings do you have to get it set?
Set up Maker Webhooks in your IFTTT, which will give you a URL to plug into the WC dashboard settings. You can trigger IFTTT from webCoRE or you could use the external URL for a piston to trigger WC from IFTTT.
Oh and any url params will be passed into $args so your request to trigger the piston might look something like https://graph.api.smartthings.com/api/token/abc123-456-7890/smartapps/installations/def098-765-4321/execute/:abc123:?johns_bmw=present&johns_harley=not+present then you can use $args.johns_bmw and $args.johns_harley in your piston.
