[D Main.EwelinkClient ] WS connection closed while sending json string about ewelink-mqtt HOT 10 CLOSED

Hi, you have a Json formatting problem.

The string '{white:{br:100, ct:0}}' is not valid Json. Json expects ” around strings (like “white”, “br”, “ct”).

So you would use the command:

mosquitto_pub -t "/ewelink_command/1001088fc6/send_json" -m '{“white”:{“br”:100, “ct”:0}}' 

You may also have to escape the ” depending on what OS/shell you are using.

You may also find that you don’t need the brackets ie

mosquitto_pub -t "/ewelink_command/1001088fc6/send_json" -m '“white”:{“br”:100, “ct”:0}' 

Let me know which of these (if any) works.

Hello Nick, thanks for your support.
unfortunately it doesn't work. I try everything for Days an read all the Comments in your code, without success.

Format looks good, but no Success
sorry about that. hope we find a solution. Best Regards

I don’t have a B2 bulb to try, but I’ll take a look tomorrow.

By the way:

mosquitto_pub -t "/ewelink_command/1001088fc6/send_json" -m 'white: {'br': 2, 'ct': 0}'

Can’t work. Json expects ” around strings.
You could try this:

mosquitto_pub -t "/ewelink_command/1001088fc6/send_json" -m 'white: {“br”: 2, “ct”: 0}'

Json formatting is very specific. It might be easier to knock up a custom device for the B2, I’s fairly simple.

Are the settings ‘white’, ‘read’, ‘computer’ etc names that you gave to the settings? Or are they built in?

from ewelink-mqtt.

Ok, the problem is that it’s sending the command as a string, not Json.

mosquitto_pub -t "/ewelink_command/1001088fc6/send_json" -m '{"white":{"br":100, "ct":0}}'

Is the correct format, I need to figure out why it’s not being loaded as Json.

Ok, found it.

I just pushed a fixed version. Try pulling it now, hopefully it will now work correctly with:

mosquitto_pub -t "/ewelink_command/1001088fc6/send_json" -m '{"white":{"br":100, "ct":0}}'

from ewelink-mqtt.

Having looked through the code (which I haven't in a while), if the B2 gets set up as a default device, with the new version I just pushed, you could also use the command:

mosquitto_pub -t "/ewelink_command/1001088fc6/white" -m '{"br":100, "ct":0}'

or

mosquitto_pub -t "/ewelink_command/1001088fc6/bright" -m '{"br":100, "ct":0}'

or computer, read, nightLight etc. as these commands should be created by the default device automatically, along with set_switch. I'm not sure if ltype is a setting (it's set to white right now) - or is read only, but that would also be available as a command, eg:

mosquitto_pub -t "/ewelink_command/1001088fc6/ltype" -m 'read'

let me know if these commands work as expected, if so, a custom device isn't really needed.

Dear Nick, I am very excited once again.
mosquitto_pub -t "/ewelink_command/1001088fc6/send_json" -m '{"white":{"br":100, "ct":0}}'
works wonderfully.
I hope to be able to derive the remaining application functions in this way.
The other Params in your last Posting i will try.
Thank you very much for your very quick response and the time you invested.
if I had your address I would send you a B2 ;-)

from ewelink-mqtt.

Glad it's working.

I don't think sending me a B2 would help as it's a Europe only product I believe (220-240V). - I'm in Canada.

It did help sort out some bugs in the send_json interface anyway!
