I'm testing "smart" bulbs again. Setup is a little difficult. Finding the instructions helped.
I bought a couple of BeeWi Bluetooth 4.0 Bulbs. They are supposed to have a range of 20 meters (about 65 feet). I haven't tested the distance yet.
The instructions in the box are tiny and cryptic, so I did a search online. I eventually found this:
2.3. Pairing
Before using Smart Color Bulb, it is necessary to securely pair the Smartphone and Smart Color Bulb together. This way, only authorized Smartphone or Tablet will be able to access the bulb.
1) Download and install the BeeWi SmartPad app.
2) Fit the Smart Color Bulb into a lamp/bulb socket. For safety, turn off the power before fitting the bulb in the socket.
3) Turn on the power. The bulb will be visible for pairing during one minute after it has been powered on.
4) Open the app and press “Add Peripheral” to look for your peripheral and initiate pairing.
5) Once “BeeWi Smart Color Bulb” is listed, select it to pair it. After successful pairing, a new box is showing in the app home screen.
