Hello,
First of all, a huge thank you for all the work you've done on node-red-contrib-tuya-smart-device, which helps many people like me who lack the necessary skills.
Here's the problem: Tuya recently changed the LocalKey format from 16 digits to 19 digits, with special characters and all the possible variations.
Would it be possible to enable the use of a 19-digit LocalKey in a future update to node-red-contrib-tuya-smart-device?
Indeed, if I copy the correct LocalKey into the node, I get a debug message saying: "TypeError: Key is missing or incorrect."
Thank you for your help.

Hi and welcome to the forum.
If you don't get a response here, you should raise an issue in the Node's GitHub repository. I just got my first Tuya devices for a remote building I needed urgent monitoring in so I'm interested in this.
I wouldn't normally use devices that might not be changeable to ESPHome but I needed something urgently and haven't had the time to set up a remote Node-RED installation yet anyway.
