Create a subghz file from known data?
For example, rtl_433 has the spec for an X10 sensor say I know what data I want to put where, is there some tool/site I could enter in what the "specifications" of the signal waveform are and the data I want to send as a byte-string or binary-string and it would create a playable .sub file for me?

New Guy: Outdoor Thermostat / automated fan start/stop.
For "outdoor distances" I'd probably stick to something LoRa or 433MHz based. YoLink has quite a few options using the LoRa protocol. I use basic 433Mhz based AcuRite sensors paired with an RTL-SDR dongle connected to a machine running RTL_433, and use Home Assistant to trigger automations and alerts.

Mystery signal?
866-868MHz is SRD/ISM band (in UK/EU). Can be things like energy meters, TPMS, medical devices etc. Try rtl_433 on it.

Problem trying to listen to a Honeywell doorbell (RF 868 Mhz) with RTL-433
I'm trying to add a Honeywell doorbell to Home Assistant by using the RTL-433 GitHub project/program. When I run the program the SDR dongle is detected but it doesn't display anything when I press the doorbell (the image shows what I see after running the program and pressing the doorbell). I have also tried Honeywell Activelink (FSK) aka [116], so I have tried both 115 and 116 decode protocols.

Millions of smart meters will brick it when 2G and 3G turns off
My municipal water meter transmits readings in the clear on the 915 MHz band. There's a neat program to catch the readings: https://github.com/bemasher/rtlamr

Installer wanted $500 to install CTs. Paid $15 for a meter reader and spent a lazy Sunday getting this dialed in
Great - thanks for sharing this! I have an enphase system that shows me my production in HA, and I can read my solar and net meters using rtlamr to figure out consumption. I use the Utility Meter helper to create a sensor showing my current net meter change. When this number is negative, I'm sending energy to the grid, and when it's positive, I'm taking energy from the grid. What I'm trying to figure out is how to create sensors that will be acceptable to the Energy Dashboard so that I can get nice graphics like you have. showing how much energy is going to or from the grid. Any help greatly appreciated.

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.

ULPT request: How can I jam a smart meter signal? [UK]
I disagree, 20 quid dongle on amazon and rtlamr allows you to read many common meters. From usage you can tell when someone is cooking, showering, or not at home. Thieves already use more advanced tech to steal cars so it's only a matter of time before this is used to scope houses for burglaries.

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.
