Setting brightness results in error

[ulab]

This is probably something that is more related to the device than this module, but I can't seem to be setting the brightness of my Yeelight Luna (ceiling light). Perhaps someone can point me in the right direction?

I can send "ct" with different color temperatures and "on" to switch the lamp on and off, but as soon as I try to send the "bri"ghtness, I get the following error:

"Yeelight "general error (code -5000)". Payload might be invalid."

[mattmattmatt]

Can you send a screenshot of the exact payload you are sending to the Yeelight node?

Unfortunately I don't have a Luna light, so I can not reproduce this error myself.

I have set up the following flow:

Clicking on the brightness button sends the following network traffic between my RaspberryPi (192.168.178.100) and the Luna (192.168.178.26):

If I use python example code from Yeelight, it just sends the following command:

{"id":1,"method":"set_bright","params":[100]}..

I'm guessing the difference is that one sends a set_scene command (which the Luna might not be able to understand because it doesn't have colors?), while the other sends the set_bright command as I'd expect.

[mattmattmatt]

Thanks for the response, all those details are very helpful!

This node-red-contrib-yeelight-compat-hue node uses set_scene to create smooth transitions between states, but in your case this might impact functionality.

When you log network traffic just like you did above but for the { "ct": 6500 } node, do you also see that set_scene is called, but without the error response?

[ulab]

Sorry for the late reply, I wasn't able to test it over the last few days and today it doesn't seem to change the color temperature anymore (unless I use the app), but it doesn't report an error either.

Sending {"ct":1700}:

[KL-AU-S]

I have the some error with the brightness. Is there any solution? Kind regards

[S474N]

I tested this and it's ok on Yeelight 320:

{"on": true,"ct": 6500, "bri": 255, "duration": 500}
