@kylelamb1324 see my sample module it’s node helper receives a message and sends one back https://github.com/sdetweil/SampleModule its string identifying the message and some buffer of data, completely up to you, string, number, structure… then on the receiving side u get the identifier, so you can tell different messages apart and a pointer to the buffer sent by the sender socket notifications are private to your module an example use the node_helper does not get any of the info from config.js like the modulename.js does so, typically the first thing would be to send the this.config buffer to the node_helper
