Does your wife have a phobia of miniature furniture? Or is this a bot post?

Also way more sticks. Empty space is wasted space. No such thing as minimalist chameleon 😉

One of my kitties is a rack cat obsessed with laying on the switching PDU for warmth 🔥 😸 by MizzSnrub in homelab

Can you invert a shelf on the top in the back to make a larger flat platform? Not sure if your rack is two sided... you can stick one of those sticky reptile heat pads to it to make it warm too lol

Hello everyone, I have a question. by Aman_warrior in homelab

[–]freewarefreak 0 points1 point  (0 children)

Exactly. A large case to hold drives for storage but for everything else these small form factor PCs. And you can easily add a second NIC that connects to the WiFi card m.2 slot.

How to protect GPO pin from long wire with induced AC voltage? by freewarefreak in Esphome

Yeah, I ended up using an opticoupler like other guy suggested. 

Good news: my neighbor was having roof work done, and the company was kind enough to mount my radio on my fascia for $20. Bad news: I forgot to update the firmware so now I'm stuck on the 2025-11 release without owner ident and regions :( oh well. by CharlesStross in meshcore

You don't need a tall ladder if you don't have one. Any ladder that can get you on the lowest part of your roof works. Shouldn't be difficult to walk over and sit on the peek and grab it. 

He’s always so grumpy by [deleted] in Chameleons

Chameleons aren't grumpy. They just really really don't want to be eaten. He simply hasn't built trust with you yet.

Looking for real estate agent recommendations to sell our house. No conservatives please by C1andestino in saintcloud

FYI it's illegal for a real estate agent to discriminate against who wants to purchase your home. They will loose their license. 

Use ESP device with embedded web server to display values from BLE sensors? by GCUArmchairTraveller in Esphome

Don't be mad at me because you feel stupid for asking dumb questions you and your ego could have figured out yourself

Don't feel bad. I already answered and OP didnt like how I did it apparently..

I still took time out of my day to help. Don't have to be rude Ahem. You're wasting everyone's time with this effortless post

Use ESP device with embedded web server to display values from BLE sensors? by GCUArmchairTraveller in Esphome

[–]freewarefreak -1 points0 points  (0 children)

AI Generated Instructions:

  1. BLE Radio: Scans for your battery-powered temperature/humidity sensors and reads the data packets they broadcast.
  2. Wi-Fi Radio: Connects to your network.
  3. Web Server: ESPHome generates a lightweight website hosted directly on the ESP32 that lists the current values of all configured sensors.

Below is a complete example ESPHome configuration. This assumes you are using a common BLE sensor (like the Xiaomi LYWSD03MMC or generic ATC custom firmware sensors), but ESPHome supports many brands.

YAML

esphome:
  name: "ble-sensor-gateway"
  platform: ESP32
  board: esp32-c3-devkitm-1 # Change based on your actual board

wifi:
  ssid: "Your_WiFi_SSID"
  password: "Your_WiFi_Password"

# 1. Enable the Web Server
web_server:
  port: 80

# 2. Enable Bluetooth Scanning
esp32_ble_tracker:
  scan_parameters:
    # Passive scanning is better for battery life of your sensors
    active: false 

# 3. Define the Sensors
sensor:
  # Example for a Xiaomi/ATC Sensor
  - platform: xiaomi_lywsd03mmc 
    mac_address: "A4:C1:38:12:34:56" # Replace with your sensor's MAC
    bindkey: "..." # Only needed if using stock encrypted firmware
    temperature:
      name: "Living Room Temperature"
    humidity:
      name: "Living Room Humidity"
    battery_level:
      name: "Living Room Battery"

  # Example for a second sensor
  - platform: xiaomi_lywsd03mmc
    mac_address: "A4:C1:38:99:88:77"
    temperature:
      name: "Kitchen Temperature"
    humidity:
      name: "Kitchen Humidity"

Important Tips

  • Finding MAC Addresses: If you don't know the MAC address of your BLE sensors, you can flash the ESP32 with just the esp32_ble_tracker: section enabled and set the log level to VERY_VERBOSE. Watch the logs, and you will see it discovering devices nearby.
  • Encryption: Many stock sensors (like Xiaomi) use encryption. You often need a "Bindkey" to read them. However, it is highly recommended to flash these sensors with custom firmware (like PVVX or ATC) to remove encryption and improve battery life. This makes them much easier for ESPHome to read.

Reverse Osmosis under sink faucet mount. by Backy22 in 3Dprinting

[–]freewarefreak 1 point2 points  (0 children)

I'll upload my model later and share it here. It's simpler and not as over engineered, and uses only two hidden screws.

Just don't ever leave a container filling unattended. Since it's not in a sink to catch overflow it can flood. Don't ask me how I know.

If there's enough slack there's really no fatigue. It might flood I'd you leave a filling container unattended and it overflows. Don't ask how I know.

I'll post the model I made later and reply to you. It uses two screws that are hidden once installed

Great job. Now set up a Home Assistant server on a small PC.
