Connect ESP32 to xiaomi Mijia-LYWSD03MMC without using HA
I want to do a little IOT project where I establish a MQQT-Broker on my Raspberry Pi and send it readings from my measurement devices (xiaomi Mijia-LYWSD03MMC). The plan is for these devices to connect to my ESP32, allowing me to transfer data to the broker on the Pi. I've successfully connected my ESP32 to my Wi-Fi and to my broker, but I'm experiencing significant difficulties in connecting it to my two measurement devices. I have essentially followed the instructions provided in this GitHub repository (https://github.com/atc1441/ATC_MiThermometer) as best as I could. I also checked some other repos but they didn't really help me as they were too big/complex...

How do you all monitor ambient temps for your drives? Cooking drives is no fun... I think I found a decent solution with these $12 Govee bluetooth thermometers and Home Assistant.

IT Room Temp Monitor
I use the Xiaomi (pronounced Show Me) Mi Temperature and Humidity monitors (version 2) and flash the firmware with a 'open source' version (here or the older one here). I've found battery life good (8 months + with the newer software on one sensor) and bar from one corrupt display (right next to an outdoor electricity feed - well the box is handy and dry) then they have just run and run and run.

feels like winter today....not touching the heating tho
The thermometers in screenshot are Xiaomi Thermometer LYWSD03MMC with ATC custom firmware. Their bluetooth broadcast data collected by some cheap chinese ESP32 board and ESPHome addon in Home Assistant.

Reminder to check your local Micro Center’s website daily. Not only did they have stock, but they’re $15 off MSRP
You can replace their firmware with one which is more open and broadcasts the values without needing to connect to the device: https://github.com/atc1441/ATC_MiThermometer

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.
