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.

ESP32-C3 Wireless Adventure: A Comprehensive Guide to IoT [pdf]
They do have example Matter projects for the ESP32-C3/S3. I assume it's over WiFi and not thread.

Matter Raspberry Pi GPIO Commander – Turn Your Pi into a Matter Lighting Device
"Securing name resolution in the IoT: DNS over CoAP" https://news.ycombinator.com/item?id=32186286
From https://github.com/project-chip/connectedhomeip#architecture... :
> Matter aims to build a universal IPv6-based communication protocol for smart home devices. The protocol defines the application layer that will be deployed on devices and the different link layers to help maintain interoperability. The following diagram illustrates the normal operational mode of the stack:
> [...] It is built with market-proven technologies using Internet Protocol (IP) and is compatible with Thread and Wi-Fi network transports.
> Matter was developed by a Working Group within the Connectivity Standards Alliance (Alliance). This Working Group develops and promotes the adoption of the Matter standard, a royalty-free connectivity standard to increase compatibility among smart home products, with security as a fundamental design tenet. The vision that led major industry players to come together to build Matter is that smart connectivity should be simple, reliable, and interoperable.
> [...] The code examples show simple interactions, and are supported on multiple transports -- Wi-Fi and Thread -- starting with resource-constrained (i.e., memory, processing) silicon platforms to help ensure Matter’s scalability.
Is there already a good (security) comparison of e.g. http basic auth, x10, ZigBee, mqtt, matter?

How to make smaller C and C++ binaries
Bloaty is a nice tool.
When I worked on Matter a couple years ago, we had the problem that its backend http://www.capstone-engine.org/ did not support Xtensa, and produced some Python tools that could take output from bloaty or similar data from readelf or elftools, and produce several kinds of report.

Renaming Starlite to LiteStar
My two cents from someone who has dealt with product name changes. Most recently I worked on the Chip repo which is now known as Matter. There are numerous references in the repo to chip despite the name change. See https://github.com/project-chip/connectedhomeip

Need help with my project
Not sure if I'm asking in the right place so I apologise ahead. I'm trying to get one of the example projects from Matter onto my esp32 (ESP-WROOM-32) using espresiff. I am doing this on my raspberry pi btw. The problem I'm having now is that it get's stuck when I'm building (idf.py build command). It's always around 800/1135 and it doesn't go past it. The one where it is currently stuck is: [804/1135] Building C object esp-idf/bt/CMakeFiles/__idf_bt.dir/host/nimble/nimble/nimble/host/src/ble_gatts_lcl.c.obj.

Building examples from project-chip/connectedhomeip repository and Matter community of developers
I'm trying to build basic examples (light device for ESP32, Python controller for Raspberry Pi) following the guides on the official repository (https://github.com/project-chip/connectedhomeip). After solving some build errors, I managed to flash the ESP32 and run the controller on the RPi. However, I couldn't manage to commission the ESP32 from the RPi, because I kept getting a weird "mDNS: Timeout" error. Did anyone here have success with it? What am I missing?
