Recently, an ISY located about 325 miles from my primary residence ceased showing programs in its device tree. On this forum, Teken did his best to help me, but finally I turned to UD. Michel worked with me for hours, finally remoting into my Mac and resolving the problem which, basically, is that Java "does not play well with the Mac". I ask anyone considering purchase of an ISY to take into account the extraordinary support available at this forum and from UD. Just try to get any substantial support anywhere on practically anything. Taking into account this level of support makes the ISY a no brainer. And that does not take into account all the amazing things you can do with the ISY. I own two and have not had a single moment's regret. 

I completely agree.

I also completely agree. The customer service of UDI is the very best.

Just this past week, I was experiencing a new development where Alexa commands stopped working for Scenes incorporating KPL's and FL's. The support I received from UDI was nothing short of exceptional. The suggested remedy  was for me to go in the Alexa app (web version), Forget all devices, and re-discover. This worked great and took me no more than just a couple of minutes. All these commands are now working as expected. Thank you Michel and Benoit.
