This wifi unit is smaller than I was anticipating (think smaller than a deck of cards), but it included a desired feature that other wifi garage add-ons lacked: a sensor to tell you definitively when the garage door is open or closed. It came packed with a lot of fasteners and adhesive stickers to give a lot of mounting options.The including instructions we're basic but not unclear. Of course with any installation each situation is unique. So my biggest challenge was figuring how and where to mount the magnet and sensor that tells the unit when the door is open or closed. At least the wiring is long enough to give lots of flexibility.Once I got everything connected and downloaded the appropriate Android app, set up from there was also similarly of little difficulty. I didn't feel the need to integrate it with Alexa or Google Assistant but it seems easy to do. Now I have a very useful interface to the garage door so that I can control remotely. As a matter of fact I was able to let a relative in the garage even though I was in another city.This small inexpensive gadget fulfilled my needs better than I anticipated.
