Could you please expand a little on the setup of a hub/gateway in your project? I found the Arduino sketches for three sensors but it was not clear to me how one would go about the gateway those sensors would connect to.

Yes, definitely. Thanks for motivating me to improve the documentation!

I switched the main project page over to GitHub, since it's a little easier to navigate. Check it out here: https://github.com/alexose/3D-Printing/tree/main/Dorothy

thanks a lot. I am looking for the longest time to get temperature sensors for the various radiators of our house's heating system (temperature of pipes entering/leaving each radiator plus room temperature, wall temperature). I found no suitable ready-made Zigbee sensors and developing my own seemed like a daunting task. Your setup looks like a very realistic option for my project.
