Looking at UPB lighting control. Which company would you purchase the products from PCS,HAI,or Simply Automated?
They are all good, if you are using a HAI panel you will want the HAI switches there is a little difference inthe protocall to report to the pannel a bit better. Other than that they are all good I do like the HAI because you can configure the LED to be different colors, or off in a bedroom, sometimes people don't like any lights on. Simply automated is a bit cheaper if you are price shopping.
But yes you need to answer the questions above what you want to control. This question is to generic.
