I realize that neither of these devices are directly related to smartthings, but I assume there are plenty of people on this board who use all three together and can help me answer the question.
I don’t get how you use alexa to control the thermostat… ecobee3 uses upper and lower limits to control. Set the high end for how hot you will tolerate and the low end for how cold you will tolerate. It then turns on the heat or the AC to either heat up or cool down when outside those ranges.
So when I ask alexa to set the thermostat to 71 degrees… it will confirm the command, but it doesn’t adjust the temp. I assume because it doesn’t know WHAT to adjust. There isn’t a target SP for my thermostat… just a upper and lower threshold.
