Using remote with FCC ID:. CHQ7225T, and using the StartDecreasingBrightness command, I receive a HTTP of 400 Bad request. HTTP/1.1 400 Bad Request Content-Length: 54 Content-Type: application/json; charset=utf-8 StartDecreasingBrightness is a valid command, as noted by the response: HTTP/1.1 200 OK Content-Length: 528 Content-Type: application/json; charset=utf-8 {"_":“d96da0d0”,“OEMRandom”:{"_":“c33ce16c”},“TurnOff”:{"_":“2ab10e78”},“SetSpeed”:{"_":“f7dc2578”},“SetDirection”:{"_":“80b91073”},“OEMTimer”:{"_":“3a3f43e6”},“StartDecreasingBrightness”:{"_":“860147be”},“StartIncreasingBrightness”:{"_":“0dc5e82f”},“ToggleLight”:{"_":“3c0b2188”},“Stop”:{"_":“aac378bd”},“TogglePower”:{"_":“e7bdb8c8”},“TurnOn”:{"_":“1af79a43”},“IncreaseSpeed”:{"_":“a66973cb”},“DecreaseSpeed”:{"_":“795be9e6”},“ToggleDirection”:{"_":“bbc186d7”},“TurnLightOn”:{"_":“80d1778d”},“TurnLightOff”:{"\_":“d7ce86c5”}} ---

Please check the body of the 400 reply, it should contain an error code plus a human-readable error message that expands on the “Bad Request”. ---

It states that an action that is retrieved using the actions query is not supported. here is the available actions: {"_":“d96da0d0”,“OEMRandom”:{"_":“c33ce16c”},“TurnOff”:{"_":“2ab10e78”},“SetSpeed”:{"_":“f7dc2578”},“SetDirection”:{"_":“80b91073”},“OEMTimer”:{"_":“3a3f43e6”},“StartDecreasingBrightness”:{"_":“860147be”},“StartIncreasingBrightness”:{"_":“0dc5e82f”},“ToggleLight”:{"_":“3c0b2188”},“Stop”:{"_":“aac378bd”},“TogglePower”:{"_":“e7bdb8c8”},“TurnOn”:{"_":“1af79a43”},“IncreaseSpeed”:{"_":“a66973cb”},“DecreaseSpeed”:{"_":“795be9e6”},“ToggleDirection”:{"_":“bbc186d7”},“TurnLightOn”:{"_":“80d1778d”},“TurnLightOff”:{"\_":“d7ce86c5”}} but when sending the command “StartDecreasingBrightness”, I recieve the error: HTTP/1.1 400 Bad Request Content-Length: 54 Content-Type: application/json; charset=utf-8 {"\_error\_id":61,"\_error\_msg":“action not supported”} ---

I assume you’re doing this: ``` PUT devices/{}/actions/StartIncreasingBrightness {} ``` You could instead try: ``` PUT devices/{}/commands/{cmd_id}/tx {} ``` Where `cmd_id` is the ID of the command that has action: StartIncreasingBrightness. ---

I was following the syntax of the documentation found at: [Bond Local API (appbond.com)](http://docs-local.appbond.com/#section/Getting-Started/Get-Device-Information) My command was: curl -H “BOND-Token: 5d8eXXXXXXXXc570” -i [http://192.168.1.47/v2/devices/3cf71c81/actions/StartDecreasingBrightness](http://192.168.1.47/v2/devices/3cf71c81/actions/StartDecreasingBrightness) -X PUT -d “{“argument”: 3}” here is what I am trying after reading your suggestion: curl -H “BOND-Token: 5d8eXXXXXX4dc570” -i [http://192.168.1.47/v2/devices/3cf71c81/commands/1bb3664a/tx](http://192.168.1.47/v2/devices/3cf71c81/commands/1bb3664a/tx) -X PUT -d “{“argument”: 3}” this gives a message: HTTP/1.1 405 Method Not Allowed Content-Length: 52 Content-Type: application/json; charset=utf-8 {"\_error\_id":56,"\_error\_msg":“method not allowed”} If I intentionally change the numeric value for the command to something random, the message changes to: HTTP/1.1 404 Not Found Content-Length: 0 this tells me that the syntax may be correct, but the actual value has no matching command, hence the 404 error. For clarification, my understanding is that if I use the commands option, that I can get the numeric values. If the commands and the actions follow the same order relationship, I should be able to correlate the numeric value for the action value. ---

Try removing the argument. `curl -H "BOND-Token: 5d8eXXXXXXXXc570" -i http://192.168.1.47/v2/devices/3cf71c81/actions/StartDecreasingBrightness -X PUT -d "{}"` ---

SUCCESS! I tested your syntax from above, and got the expected result! Thank you for your patience. ---

Ok. — Our error message there is wrong. It should say “action does not accept an argument” or something like that rather than “action not supported” ---

This syntax worked for me to control my somfy awning. The api documentation is good but a little unclear ---
