The smart home extensions are good, they give you accesses to switches and thermostats, but you cant really get the status of anything. We wanted more so we created custom skills that went far beyond the Smart Home Extensions. I created AskHome for programmers using this technique, and Michael created Ask Alexa which helps anybody talk to ANY smartthings device. They are both complicated to install, but well worth it…and Michael has a big list of step by step instructions to insure your success with Ask Alexa. Give it a try!
