Hi,

first of all thanks for your great work! Unfortunately I am running into an error using node-red-contrib-luxtronik2.

node-red: 0.19.5 node-red-contrib-luxtronik2: 0.3.0 Novelan LD5 heatpump. Luxtronik2 firmware: V2.79

Error message: Dec 28 12:41:05 loxberry Node-RED[15443]: 28 Dec 12:41:05 - [red] Uncaught Exception: Dec 28 12:41:05 loxberry Node-RED[15443]: 28 Dec 12:41:05 - RangeError: Index out of range Dec 28 12:41:05 loxberry Node-RED[15443]: at checkOffset (buffer.js:977:11) Dec 28 12:41:05 loxberry Node-RED[15443]: at Uint8Array.Buffer.readInt32BE (buffer.js:1142:5) Dec 28 12:41:05 loxberry Node-RED[15443]: at Luxtronik.

Maybe it's because I changed the default Luxtronik webserver pw from 888888 to another one?

Hey, thank you very much for reporting. I don't think the password is needed for access at all. So I don't think, this is a problem. Or did you mean the ethernet port number? It seems, as if your luxtronik respond an unexpected data stream. I also don't know the Novelan LD5. But this shouldn't matter if you have a Luxtronik2. Witch node.js version you are running node --version?

No response, so I will close this.
