Show HN: Extend Zigbee sensor range with LoRaWAN

This is great, thanks for doing this!

I think it is somewhat common situation, when home zigbee network does not reach e.g. garage or some other near-distance building. Usually there is some ethernet/wifi network on the satellite building. So distances what LoRaWAN can reach, are not probably even needed.

Read a bit about the implementation, but I think it is easier to just ask: Could this work over general TCP somehow?

Thanks! Your question is an interesting one: Forwarding TCP over LoRaWAN seems at first impossible due to large packet sizes (from LoRa perspective!). It turns out there have been some efforts to apply dictionary based compression methods to carry different protocols over LoRaWAN. You might want to check out RFC 8376 for details.

Ah yep.

But I was mainly trying to think how to extend Zigbee-network over TCP (without LoRaWAN).

Currently it seems to be almost impossible.

If you have multiple LAN Zigbee controllers, like a ZigStar UZG-01, you can use multiple instances of zigbee2mqtt and hook 'em all into Home Assistant.

Yes, thats true, but that also means multiple zigbee networks.

Goal here would be one zigbee network which is extended to satellite location over TCP.
