[mqcmd196]

The rosnode for using switchbot.

[mqcmd196]

@k-okada By the way, I found the official Web API at https://github.com/OpenWonderLabs/SwitchBotAPI#getting-started . (To see the commit log, this API was released after my bthesis.) If we use it, I think we don't have to use the IFTTT anymore. Should I make switchbot_ros based on this API?

[mqcmd196]

I confirmed this API works with our lab's switchbots.

[k-okada]

I see , it make sense that switchbot_ros package uses SwitchBot API.

[mqcmd196]

Okay, I'll remake this package using API.

[mqcmd196]

@k-okada It's ready for review.
@708yamaguchi @sktometometo Could you test this PR on your demos, especially Fetch's kitchen demo and Spot's demo? I think it might be work if you follow the README.

[708yamaguchi]

Nice PR!

1. Could you please add roseus function so that our robots can easily call /switchbot_ros/goal?
   like below:

(defun control-switchbot (name action)
  (cond ((equal action "xxx")
...

2. What was the DeviceType of switchbot we have? Bot?
   It would be helpful if you could give me a sample roseus code to turn on and off the lights in the 73B2 room.

We have bot and meter I think. I'll make sample eus code later.

for efficient python coding, you can use flake8 to check your code.
pip install flake8

[mqcmd196]

@knorth55 Thanks, I fixed.
@708yamaguchi I added the euslisp code. Could you try it?

[mqcmd196]

To use on eus,

roslaunch switchbot_ros switchbot.launch token:=YOURTOKEN

(load "package://switchbot_ros/scripts/switchbot.l")
;; Please setup your device name by your phone at first. Please see readme.
(control-device "/eng2/7f/73b2/light1" "turnOn")

[knorth55]

sorry, but I found few more changes.

[mqcmd196]

Okay, I fixed.

[mqcmd196]

Was the travis timeout?

[k-okada]

@mqcmd196 please add elevator example, also create an image/slide that explain this system
