Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Show HN: Extend Zigbee sensor range with LoRaWAN
This is a fantastic idea, thanks for sharing. I feel like LoRaWAN and LoRAMESH are the perfect solution for shuffling messaging around for home and property sensors, easily traversing a couple miles in poor conditions.
Prior to seeing this I was thinking about how to use the Meshtastic [0] project to fundamentally provide simple UDP services for message brokering over LoRa. There are so many sensors that could easily hook or connect to devices acting as network routers that could bridge other protocols across long distances very easily.
Have you looked at doing something similar with ZWave at all?

Seriously, I think more and more about building a LoRa network with friends. https://meshtastic.org/

FCC will vote on plan to remove outdated amateur radio technical restrictions
Agreed-- at least relaxing the restriction for UHF/SHF signals on a "secondary usage" basis (traffic must yield to plaintext). Potentially with with reduced power (say 100w) or minimum directionality, but I think a 'secondary usage' would be sufficient. Without doing so virtually all experimentation will continue to be deflected onto the ISM bands and we will lose our allocations through disuse.
So long as identification is still decodable, spectrum usage can be managed.
It's sufficient to prohibit commercial usage you don't need plaintext to do so. The old threat of tow trucks and cab services moving onto ham-bands had long since been mooted by ubiquitous cellular, but even if it weren't any significant commercial usage will eventually have a whistleblower. Usage that is obscure enough to not be vulnerable to whistleblowers could also be hidden just as well in "plaintext" traffic that was really uncrackable steganography.
As it stands you can't even lawfully log into your own personal systems over amateur radio even if you take the unreasonable steps of using specially modified software to authenticate-but-not-encrypt because inevitably some third party will send a message to you via the internet that contains some naughty words that aren't permitted over the radio.
Without relaxing the encryption rules, innovative radio usage like meshtastic (https://meshtastic.org/) will continue to be pushed onto ISM bands where (1) they're still technically unlawful because the homebrew hardware is not type-accepted (amateur bands are the ONLY place where homebrew intentional radiators are allowed!) and (2) where the band choices, power limit, and EIRP limits are detrimental to full exploration of the possibilities.
Besides, the FCC has long allowed proprietary, license fee bearing, patent encumbered digital modes. These are very close to encryption in terms of their ability to lock others out of ham comms, and have frequently been used by amateur radio groups to establish "lid free" communications channels. (Because most of the more irritating people aren't technically sophisticated enough to adopt some new mode without help, and people won't help them...).
The rules as they stand punish honest people who follow the intent and spirit of the rule in favor of people willing to just ignore the rules (including operating unlawful devices in ISM bands), willing to use stego, or willing to use obscure protocols to achieve the same ends that they'd otherwise achieve with encryption. It blocks modern networking by disallowing standard internet-grade software use with radio since all of it has integral encryption which generally can't be disabled to prevent downgrading and cross domain attacks in contexts where the encryption is needed -- or because in some cases the protocols are designed in such a way that authentication without encypherment isn't possible.

Qaul – Internet Independent Wireless Mesh Communication App
Meh.... very very low range.
For ~$20 you can get a LoRa dongle and https://meshtastic.org/, and with some luck (someone putting a node on a hgh building or a hill), you can reach quite impressive distances.

I used Serval for a bit years while doing some work with outback communities, great to see more work on these kinda project - keep up the good work!

sharing information about communication methods
I am not an expert or anything close, but i downloaded this one https://www.servalproject.org/ and it seem to work. The technology exists for a while now so there are meany implementations of it if this one dosent work out.

ELI5 Why can't cellphones connect to each other directly, acting like walkie talkies, at distances similar to their ability to reach cell towers.
Serval Project did it for a number of years https://www.servalproject.org/. Using mesh networking and existing phones wifi. They were initially designing the solution for emergency/disaster relief scenarios and had success in trials. I played with it on my mobile devices and was pleasantly surprised. If you are geeky; think batman mesh with asterisks, using your mobile phone. Not too sure what happened with it though. If you're not geeky, think airdrop but with a phone conversation, roughly the same distance
