Controlling Harmony Activities via new API

For all of you upset about loosing control over Harmony, it is easy to change activities using the new method (although the rest is a bit complicated)

To create an on off activity (assuming you know the activity ID’s) you do the following.

Create a new device in HA-Bridge.

On Item Type > HTTP Device. Target Item > http://HUB_IP:8088 HTTP VERB > POST HTTP BODY {"cmd": "harmony.activityengine?runactivity", "params":{"activityId":"ACTIVITY_ID"}}

HTTP HEADERS [{"name":"Accept","value":"utf-8"},{"name":"Origin","value":"http//:localhost.nebula.myharmony.com"}]

Content-Type > application/json

Click Add

And repeat for the Off Item but change activity ID to -1

There is a HTTP post which tells you what device commands are in an activity but to issue those device commands it’s the same as a normal device command.

Get device commands use this in the body of the request.

{"id": 23771041,"cmd": "harmony.engine?config","timeout": 90000}

Then I use the following JSONata command to filter the results to only show the activities and the device commands available to that activity

{
  "Activity": data.activity.({
  $.label:$.id,
  "DeviceCommands": $.controlGroup.function.action
  })
}

To issue device commands it’s best to use Websocket, I will update my repo with websocket commands later on.

Let me know if that helps.

XMPP is enabled again so using WS might not be needed anymore https://community.logitech.com/s/question/0D55A00008OsX3CSAV/update-to-accessing-harmony-hubs-local-api-via-xmpp
