i want to use a smoke detector on one hub to trigger an alarm on a different hub on the same network, I have a large property and have had to use 2 hubs but this non communication between the 2 hubs is so stoopid, how come this cant be fixed its just programming. both are both smarthings hubs.
Iâm sorry, Iâm confused. 
What are the brand and models of the two hubs you are referring to and what do you mean by trigger an alarm?
Because SmartThings customers Have been able to include devices connected to two different hubs in a single routine for some time now. So you could, for example, have a motion sensor in one building on a property trigger a siren in a different building connected to a different hub if you want to. The two hubs just need to be defined as belonging to the same SmartThings âlocation.â
Can you be more specific about what youâre trying to do?

Both are samsung, i have not seen this in creating a routine.
Are they in the same âlocationâ in your account?
Is the official Web interface to your SmartThings account. Select each hub and see what âlocationâ it says on the details page.

@orangebucket notes in post #10 below that SmartThings allows you to give two different locations the same name, so my suggestion will not be enough.
.
Instead, use his suggestions in post #10 to confirm SmartThings sees your two hubs as being in the same âlocation.â
Also, what is the model of each hub?
they are gen 2 smarthings hubs
And both are in same location
I just tried to make a routine and it doesnât give me option of the other hubs devices.
Iâm going to tag a few people who I think do have more than one hub just in case Iâm missing something that theyâre aware of.
I have 2 v2 hubs in the same location. Just tested adding a routine to a device on one hub and it allows the control of a device managed by the second hub, using the normal rules with routines. In my example, both are zwave but it shouldnât matter.
I have 3 SmartThings locations on a single SmartThings (Samsung) account.
My primary location has a single v2 hub.
Like you my 2nd location has 2 hubs due to the space separation between buildings. One hub is an old v2 and the other is a new ST Station.
My 3rd location is only for testing and donât have a hub.
I can not write SmartThings Routines using devices at 2 different locations. But I can use SharpTools to write rules using devices at 2 different locations.
I have no trouble writing routines between devices on the 2 hubs at my 2nd location. I just wrote a cross hub routine as a test.
So my guess is that your 2 hubs are connected to 2 different SmartThings locations on a single SmartThings account.
If all else fails you can use SharpTools to write rules between your hubs.
SharpTools is a 3rd party integration with a Rules Engine and Dashboards.

So can we focus on the Location again? If you go to the Devices page in the mobile app and select the All devices âroomâ do you see both hubs and all the devices listed on the one page?
I am asking that because it is all too easy to create multiple Locations with the same name in SmartThings so just looking the name of a Location a device is in doesnât always help. OK youâd probably have noticed if you kept having to switch Locations at the top of the page in the app to see different sets of devices, but Iâve never encountered the issue youâve described and I canât recall it being mentioned either.
I suppose for completeness I should suggest you go to the three dot options menu on the Devices page and choose Select devices to use just to make sure all your devices are shown and selected there.
I should perhaps have also suggested going to the Favourites page and selecting Manage hubs from the option menu. That is pretty unequivocal about stating which hubs are in your Location. Itâs new so I hadnât thought about it.

both hubs have 2 different names and have the same geo location exactly. yes i have to switch between them using drop down menu top left to see each device paired to that hub. On the all devices page it only lists the devices that are paired to that hub, i have never been able to crossover to the other hubs devices while making routines.
trying to get everyone on same page about Location vs Geolocation.
if you go to this link: https://my.smartthings.com/advanced/locations is there only 1 location listed?

âLocationâ in SmartThings is not the same as your physical Geolocation. Itâs just a term that they use to mean a group of devices that they will treat as belonging together.
Devices in the same âlocationâ can be included in the same routine.
Since you have your account setup so that your hubs are in two different âlocationsâ, thatâs why you canât combine them.
The easiest way to get around this is, as was mentioned above, to use the third-party app âsharptools.â this is a very popular app and you can read a lot about it in the forum. It has its own rules engine built in, and it allows you to combine devices from different SmartThings âLocationsâ in one of the rules you build with sharptools. They have both a free level and a paid âproâ level. I think you will probably only need the free level, but you have to check it out to see.
If for whatever reason, you donât want to use sharptools, you would have to rebuild your account by putting both hubs into the same SmartThings âlocation.â But that would be a lot of effort, so Iâm not sure if it would be worth it to you or not.

2 locations
House (hub 1)
Office (hub 2)
both with same geo address and on same network
i was not aware you can put 2 hubs in same location?
Originally, we could not, but they changed that a couple of years ago. In fact, they now recommend it because they even allow multiple hubs in the same location to be connected into one âmultihub network.â
Itâs part of their âhub everywhereâ initiative. Now that they are building hubs into many Samsung brand devices like smart televisions, smart speaker bars, smart appliances, etc. they want those all to be able to work together easily.

so i suppose theres no way to drag one hub over to the same location?
Unfortunately not at this time.
well that sucks, i suppose i can buy a new hub and migrate the devices to a new hub instead of starting all over? i thought i seen that option somewhere
and this sharptools i am assuming its all cloud based? i trying to stay away from cloud and have all local
Routines involving devices on 2 different ST hubs at the same location will run in the cloud not locally. I just wrote a test routine to confirm this.
So in that case the ST routine is no better than a SharpTools rule.
SharpTools is very powerful and can do things that ST routines canât. So you might find that you like it.
