The official integration between Logitech Harmony and SmartThings doesn’t seem to work.
Trying to follow instructions at Harmony and SmartThings I only see Philips Hue and Hunter Douglas Powerview Hub in the list of Home Control devices.
The SmartThings Community article Can't add Logitech Harmony Hub to Smartthings app hints that the support for adding Harmony from SmartThings has also been deprecated at least in some regions. It seems that there is a workaround: installing a community device handler. I believe that by installing the device handler I’d be able to control Harmony devices using SmartThings but not vice versa - e.g. SmartThings switches from Harmony remote.
My use case would be mainly getting the events from Harmony devices and having them toggle (virtual) SmartThings switches.
Should that already work using existing solutions?
If a working solution doesn’t exist, is there someone already working on the topic?
Since Loigitech has an API for Harmony, would it be possible for me to write a custom integration between Logitech and SmartThings? (Not only technically but also actually - is there a requirement that I be an official Logitech representative?)
What would be the modern way of implementing the integration? I suppose I’d need to use SmartThings Schema and have my own server running listening events from the Harmony API and feeding them to SmartThings API. In this scenario, the Harmony hub and the SmartThings Hub are both in the same LAN. Even if my integration server was in the same LAN, it would have to have and Internet-accessible secure port in order to communicate with the SmartThings Hub, right?
I’m sorry to ask such newbie questions that probably have been answered already dozens of times somewhere. It’s just quite hard to find relevant information from the community forum due to vast number of legacy information.
