I have installed the following HACs integration for Gold Air Heaters (basically a tuya device).
The instructions for determining the local key are however out of date and I can’t seem to work it out using new instructions that I also found. ( nicole-ashley/homeassistant-goldair-climate: Home Assistant integration for Goldair WiFi heaters, dehumidifiers and fans (github.com))
Has anyone successively completed this integration recently? If so could you please assist me with some simple bullet points? 
Thanks
