I have added basic activity management to the driver now, The commands will have been added to end of the list of device commands
e.g. To start an activity it would be something like {“activityId”:“47722264”,“action”:“startActivity”}
There is also a bit of magic to close/poweroff the current activity which is to run the following
{“activityId”:"-1",“action”:“startActivity”}
These updates will take up to 12 hours to land on your hubs and please see my note on the original post about how to force a re-connection if it stops working after the driver upgrade.
