Today, I've got a new air conditioning unit from Mitsubishi Heavy Industries. Each indoor unit contains a WiFi module which responds to JSON requests sent as HTTP POST to port 51443 and is usually accessed using the "Smart M-Air" app on a smartphone.
Unfortunately, the response is encoded in some weird way.
Some guys already implemented controlling the units via Home Assistant and ioBroker. Unfortunately, I have no experience in writing my own Node-RED nodes. Therefore, my question: Maybe someone already tried to experiment with the API of those WiFi modules or maybe already created something working for Node-RED. At least I couldn't find any nodes yet.
