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.

Building a Weather Station
Why wait?
Those fancy weather stations often transmit to the indoor LCD display using fairly simply messages sent in the 433 MHz band or the 915 MHz band. For many those message formats have been reverse engineered and decoders for them added to open source SDR software such as rtl_433 [1].
With a $30 USB RTL-SDR and rtl_433 you can then use the sensor units from many of those fancy units as inputs to your own display and analysis software. And you can often use your neighbors' sensors too. One of my neighbors--I still haven't figured out which--has an AcuRite 5-in-1 system and I can see its readings using my RTL-SDR and rtl_433.
If you build your own sensors it is cheap and easy to add a 433 MHz transmitter and define your own message format. Rtl_433 can be extended to cover new message formats by giving it a config file that describes the formats.
There's a driver for Weewx to let it use rtl_433 [3].
You can get an RTL-SDR and rtl_433 now, and start playing around with whatever sensors others in your neighborhood happen to have.

[Newb] Need help with wind speed\direction sension
Outside of that, any of the consumer weather stations (or cheaper rebadged options) that transmit via RF433 could be picked up with a cheap SDR dongle and converted to MQTT topics using rtl_433 for use within Tasmota.

Monitoring My Weather at Home
Looks like you can skip the logger and get a cheap rtlsdr to log data wirelessly (using e.g. https://github.com/bemasher/rtldavis).
A cheaper still route would be to grab the outdoor sensors for a weather station supported by [rtl_433](https://github.com/merbanan/rtl_433) (or receive signals from a neighbor!)

GitHub - merbanan/rtl_433: Program to decode radio transmissions from devices on the ISM bands (and other frequencies)
There are some notes in the docs https://triq.org/rtl_433/ANALYZE.html And some guides in the wiki https://github.com/merbanan/rtl_433/wiki

Finally got something on 915MHZ
That report is a false positive which was fixed only 3 month ago: https://github.com/merbanan/rtl_433/pull/2214 You likely want to try the 22.11 release.

Smart natural gas meters or analytical models to determine hourly usage?
this varies by meter but if you are into tech you can listen for the broadcasts with a rtl-sdr and https://github.com/bemasher/rtlamr software

Can I size a heat pump purely from historical gas usage?
Using an RTL-SDR device configured to read meter data. I have it connected to my HomeAssistant smarthome setup to log the data and populate energy usage dashboards.
-
Public Central Hudson API?
Absolutely! I'm using a Nooelec NESDR Mini as a Software Defined Radio connected to a raspberry pi that's running a program called RTLAMR, which will pickup all the Automated Meter Reader signals in the area. There's some research you'll have to do to find your meter ID, manufacturer, and protocol, but once you have it narrowed down to your meter you can publish the entries to an MQTT instance using rtlamr2mqtt, where Home Assistant can pick it up and use it to track your total energy consumption.

Interesting things to receive with SDR in 2023?

F.lux, but for Your House
Not OP, but in my jurisdiction the smart power meters broadcast consumption as SCM at 900MHz. rtlamr
https://github.com/bemasher/rtlamr
does a good job of receiving and decoding those broadcasts using a cheap SDR. My local water utility also broadcasts consumption as SCM+, also 900MHz. I'm able to grab both with the single SDR.

Just got my RTL-SDR kit
The most fun things I did with mine was reading power meters of my neighbors (https://github.com/bemasher/rtlamr) and planes flying nearby (some secret planes didn't broadcast signals though, probably FBI)

Northwestern energy advanced electric meters
In fact, I was able to get around 150 unique readings in my neighborhood, just using a USB software defined radio, and this project on Github: https://github.com/bemasher/rtlamr
Then I use the RTLAMR package (written in Go) from here https://github.com/bemasher/rtlamr
