# iRobot Binding
This binding provides integration of products by iRobot company (http://www.irobot.com/ (opens new window)). It is currently developed to support Roomba 900 series robotic vacuum cleaner with built-in Wi-Fi module. The binding interfaces to the robot directly without any need for a dedicated MQTT server.
# Supported Things
- iRobot Roomba robotic vacuum cleaner (https://www.irobot.com/roomba (opens new window)). The binding has been developed and tested with Roomba 930.
- iRobot Braava has also been reported to (partially) work. Automatic configuration and password retrieval does not work. Add the robot manually as Roomba and use external tools (like Dorita980) in order to retrieve the password.
# Discovery
Roombas on the same network will be discovered automatically, however in order to connect to them a password is needed. The password is a machine-generated string, which is unfortunately not exposed by the original iRobot smartphone application, but it can be downloaded from the robot itself. If no password is configured, the Thing enters "CONFIGURATION PENDING" state. Now you need to perform authorization by pressing and holding the HOME button on your robot until it plays series of tones (approximately 2 seconds). The Wi-Fi indicator on the robot will flash for 30 seconds, the binding should automatically receive the password and go ONLINE.
After you've done this procedure you can write the password somewhere in case if you need to reconfigure your binding. It's not known, however, whether the password is eternal or can change during factory reset.

# Known Problems / Caveats
- Sending "pause" command during missions other than "clean" is equivalent to sending "stop"
- Switching to "spot" mission is possible only in "stop" state. Attempt to do it otherwise causes error: the command is rejected and error tones are played.
- Roomba's built-in MQTT server, used for communication, supports only a single local connection at a time. Bear this in mind when you want to do something that requires local connection from your phone, like reconfiguring the network. Disable openHAB Thing before doing this.
- Sometimes during intensive testing Roomba just stopped communicating over the local connection. If this happens, try rebooting it. On my robot it's done by holding "Clean" button for about 10 seconds until all the LEDs come on. Release the button and the reboot tone will be played. It looks like there are some bugs in the firmware.
