Thank you @Adrian_Rockall for your quick response and thank you as well for developing the app !!
I am new to Homey, just installed 2 weeks ago, so I was not aware of the existence of a community store. I will try it.
I understand that what the app does is to connect homey to smartthings hub and then enabling to interact with the devices already installed in Smarthings hub through Smartthings hub, is that correct?
