First of all, this is not an attack or intended to be negative. I often get attacked or downvoted for constructive feedback on Show HN (where that's what it's here for). This is intended as feedback. I give feedback to the best projects and to the worst.

With that out of the way:

Many of us have never heard of LoRa. There is no way to know in 60 seconds what this project does, or why it is useful. I would recommend adding a sentence to the effect of:

"LoRa is a low-cost long-range wireless communications protocol. This project provides hardware and software to allow zigbee devices to communicate over LoRa, allowing placement of such devices far from the zigbee hub."

That's a small but big improvement. Next improvements:

- Discuss maximum range / interference

- Add an English option to the project page

- Minor: Reorganize the page to be more directive about how to get started ("Buy X, do Y, etc. in a tutorial format"). This can even just be a pointer to the relevant pages ("Buy the hardware list on [this page]. Install the software per [this page]")

That's a first impression. Feel free to post again. Show HN is a nice place to get first impressions, which have a surprisingly big impact on adoption.
