Not needed. One Switch Bot is enough to handle a wall switch with an optional add-on (shipped with Switch Bot). Please check our demo video https://youtu.be/GGBjUusWmU4 .

Yes, IFTTT is already supported in our software (with Switch Link).

Yes, our Homekit function can be done with Raspberry Pi or openWRT.

The Apple certification will take much money and a long time which may delay our shipping schedule and increase your cost (the MFI chip is not cheap). But you still have two ways to enable Homekit:
1. Using Raspberry Pi or other boards to bridge Switch Link to Homekit as we currently do. We will release a tutorial on how to set up homekit with Raspberry Pi before shipping. In short what you need to do is just inserting a SD card with our firmware to your Raspberry Pi - power on- - configure your WiFi password, then it is done!

2. We are sure there will be third-party firmwares of Switch Link with Homekit support released in our community, then you can enjoy Homekit with Switch Link standalone.

Yes, this feature is already supported via IFTTT (Switch Link involved). Please check our demo videos in the Gallery section, there is a demo showing controlling a printer by Alexa voice commands.

Yes, the timer function is already built in our software. You can set the timers (up to 5 and can be extended) inside a Switch Bot as easy as adding an alarm in your smartphone.

Your cute robot is smart and can handle its task itself, so do not worry your smartphone is away.

Sure, more customized actions are added like multiple clicking, pressing down - holding for a while - back. Our team are also optimizing the App UI to let you define your own special actions.

You can set a password for your Switch Bot just like setting for your WiFi routers.

This depends and ideally 2cm without any tape. But you can insert more tapes to adjust the height of bots. Some specs of the robot arm FYI: length: 13.1mm, swing center height：7.8mm, swing angel: -45-90°.

Technically, Switch Bot has up to 10N pressing strength listed in our spec, which is able to press most switches. It is a trade-off between the pressing time and the strength based on our mechanical design, which makes us able to customize a stronger version (higher than 10N) if strong demands there.
