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.

How I keep myself Alive using Golang
Slightly related, but I've also been working on and off for a few years on my own Type 1 Diabetes management solution (https://github.com/algao1/iv3).
I haven't had time to work on it recently, but it uses ntfy (https://ntfy.sh/) to send alerts and such.
I was thinking of eventually incorporating some kind of automatic remedial solution eventually to help keep my glucose in range, but haven't had any time to look into it yet.

FBI using push notification tokens to identify anonymous users
If you go to the settings, there should be a notification category, which then contains another menu "App Notifications" where you can see all the apps that are allowed to receive notifications, but I don't know if this will stop google play services to receive these identifiers.
I use GrapheneOS, so I don't have any google play services running, but for the apps where I need notifications I use https://unifiedpush.org/ (only a few apps implement it) and I host my own https://ntfy.sh server.

Ask HN: What apps have you created for your own use?
Kind of similar, in the early days of COVID, I accidentally discovered that my state's website would have test results available several hours before they sent out the "view your results" email. So I made a script that would check the site every five or ten minutes and then ping me as soon as the result changed to something besides PENDING.
In the course of that I stumbled on https://ntfy.sh/ which solved the notification problem without needing Twitter, and I've used it since then to let me know when long-running scripts complete.

For further monitoring & alerting about critical cpu temperatures (unlikely now) for example, I plan to use notify & something else. Haven't thought about this much yet though.
