Launched in 2015 and discontinued in 2019, the Leeo allowed you to use a couple of sensors and link it to actions that would give you text alerts and a phone call. For instance, it could listen for smoke alarms and call you when it heard them, or it can let you know when it got too humid or hot at your house. However, the company had the wrong business model as it only charged $50 for the device and had no recurring revenue. Plus they were unable to come up with additional products.
