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.

Building a DIY Smart Doorbell
While using an RPi is fun to get into and set up yourself, there's starting to be cheaper and better hardware featured controllers for doorbell projects like these, such as the Lilygo TTGO, an ESP32-based board with built-in camera, display, button and wireless for anywhere from U$15-25.
