I have been using the documents found at https://github.com/Yeelight/Yeelight-Chroma-Connector to try and control a Bedside Lamp 2 from node.js. I can get the list of supported methods, and I see that “udp_sess_new” is listed there. But, when I try to use this method, I get a response error code -1, message “method not supported”. I am able to use other methods successfully, such as “set_rgb”.
