【Smartly Control Your Traditional Appliances】Fingerbot is compatible with various buttons and switches(except touch screen button). With the included Add-on sticker, it can simply stick to any surface and retrofit your old appliance. 【Touch Button】The newly upgraded Fingerbot Plus is designed with touch buttons on the device, which can easily control the robot arm on/off by touching your finger, and turn the traditional switches and buttons into smart buttons through the robot button pusher. 【Even better with Tuya Bluetooth Hub】With Tuya Bluetooth Hub, you can control your FingerBot remotely from anywhere and enable voice control. Works well with Amazon Alexa and Google Assistant. Timing functions still require a Bluetooth gateway. 【Easy Installation】Tape it right next to a rocker switch or button with a 3M sticker in 5 seconds. No swapping, no tools are required. 【Enegry Saving】The newly upgraded Third-generation finger robot is powered by a replaceable CR2 battery(battery include).
