A:Answer I haven't tried that setup yet, But from what I can find, the 950 Remote is Dependent on the Harmony Hub in order to work, Without the Hub, you lose the Alexa Compatibility, and most of the Advanced Features, etc... ALSO it won't be Mobile Capable either, But everything I can research on it says it won't work in General without the Harmony hub...
To buy the Remote & Hub together isn't that much more expensive, but why wouldn't you want to buy the Hub, It gives you access to EVERYTHING around your house: Smart Lighting Systems, Air Conditioning, Heat Pump, Smart Locks & Garage Door Openers, Security Systems, Other AV Devices, Literally, EVERYTHING in your home, etc... It just makes sense to buy the Remote "In Case" you decide to upgrade in the Future...
