I came here looking for this exact solution and found it, i am not much of a computer guy at all, but found the instructions and managed to get it up and running very well, albeit after a week of torture, i managed to find all the solutions here in the forums, personally i thinks works well and i cannot find anything else near, to do what Monocle does.
I do have a Smartthings hub which seems to predominantly work via Github and have only ever had headaches trying to install and get stuff working with the open source stuff, it just seems to be a minefield, a confusing one especially for people like myself who just want a nice .exe to do all the work, to the point where my ST hub is just a coaster for my cup of tea now. I cannot even get my Sage doorbell to work though ST to Alexa and all i see recently on the forums is people complaining.
The majority want something that just works and Monocle seems to, without to much hassle.
