I just added a Wayne Dalton WDTC-20. As specified for the 2.3 build 4, was able to display temp and set temp ranges.
I am looking forward to being able to set tempature points based on calendar / time of day.
I did setup the WDTC-20 as an area and am able to turn the area on /off (normal / save) using event scheduling (mode temp range). This takes care of 80% of my requirment.
Keep up the good work on improving ThinkEssentials. When I can control temps based on time of day, then I will add more WDTC's for the remainder of zones in my home.
