I’m not feeling very well today, so I can’t give you a detailed answer on the harmony, but the short answer is that each harmony activity that you already have set up should have been added as a virtual switch when you added the harmony to your smartthings account. After that, you can turn those switches on and off with any of the existing smartthings features.
Hope you’re feeling better today? After a bit of troubleshooting, it appears that the problem is with the Harmony hub losing Wifi signal (even though it’s located right next to the router). With no option to connect via ethernet, todays mission is to try get it to reliably hold a wifi signal to all the Smartthings integration.
This is a popular request. There’s no way to do it using the official echo features, but there are two different groups of community members who have built code that can do it using SmartThings plus echo. It’s technically quite complex, and you are going to have to sign up for an Amazon developers account, but there are lots of people who will help you if you were interested.
The two different projects are AskAlexa and EchoSistant. You can find both listed on the quick browse list for “voice” in the community – created wiki.
There is also a third project that can do just voice notifications called LANnouncer. It’s just using the echo as a Bluetooth speaker, so you don’t need the developers account and set up is somewhat easier. But that one doesn’t let you ask if the door is open, it just announces if it is. That might be enough for your needs, I’m not sure. Again, all three are on the “voice” quick browse list.
