Great idea, easy setup BUT. No integration with IFTTT or Smartthings. VERY unstable integration with Alexa and Google Home. I would put this purchase aside if you plan on using it with another system for now. It's a 5-star product if you want to use it as a standalone system, but it's not very user-friendly. Once they fix this issue I will buy more of these. Why not offer a Z-Wave or ZigBee option? had to downgrade it to two stars. I like the concept here very much, but the company cannot implement it. I have many smart switches from different manufacturers, divided between two houses. This is the most unstable. I have to re-enter Alexa command codes every other day. I'll switch it to my google and see if it works better. Two days later; It was with my Google Assistant. Same problems, very unstable, keeps crashing. This works wonderfully in a separate app. If they just made them like Z-Wave or Zigbee devices and kept the price low, they would have cornered the market. Setup is that easy. I would put them on all my switches
