  1. Confession: I am a #Govee guy. Not so much the LED light strips (that's my son's domain).

    Me, I am a temperature sensor guy. I have them in my fridge and freezer to mitigate food spoilage, one in a watertight container in my pool skimmer, one in a far dark corner of my basement to turn the dehumidifier on and off. One in garage to make sure it isn't too cold in the winter, one in my bathroom to turn a small space heater on and off in the winter. One in my gazebo so I know the outdoor temperature. I have two in my mum's 1960s apartment to make sure she's staying cool in the evermore frequent heat waves (set those up a few weeks ago after she called to say she wasn't feeling so good and I rushed over to take her to emergency where she was treated for heat stroke and severe dehydration. Govee will make sure that I have advance warnings now - plus we bought an AC for her apartment).

    Yesterday I added one more sensor, their PM2.5 air quality sensor. It gets good reviews for accuracy (it uses the Cubic PM2008MS as its PM sensor) and is significantly cheaper than competitive products, at under $50 Canadian. This sensor is helpful because of the ever increasing number of wildfires and resultant smoke. While Environment Canada issues smoke warnings, smoke and associated air quality can be extremely local (think blobs of smoke that fall from upon high and roll through your neighbourhood). Having this sensor will warn me when AIQ is poor (it samples every 2 seconds and can trigger threshold alerts via the Govee app), and sadly, during smoke events, will also let me know when locally the AIQ is acceptable, giving confidence about when it is prudent to go indoors, and when it is okay to enjoy being outside.

    Next up, I guess I'll need another one for indoors. Then the smart switches can turn on the Corsi Rosenthal air filters.

    Welcome to the second quarter of the 21st century.

  2. 💁🏻‍♀️ TIL: 🩸🧊 Iron rich #saltwater trapped beneath Taylor #Glacier for over a million years seeps out in red pulses that look like bleeding.

    A 2026 study from #Louisiana State University caught an outflow in action using #GPS, #cameras, and temperature #sensors. #Sulfate breathing #bacteria thrive in the dark brine, making Blood Falls a model for life on icy worlds.

  3. 🇨🇦🍁 Oh no, the #U.S. is yanking its #ocean #sensors and #Canada is SHOCKED—because apparently, the impending #El #Niño is a Canadian-exclusive #weather event. 🤔🔍 Time for them to dig deep and find a new excuse for talking about the weather, eh? 🌊🌀

  4. After testing 7 #LilyGO #TBeamSupreme units, one thing is clear:

    👉 Magnetometer calibration is not transferable between devices.

    Even in similar environments, raw readings varied dramatically between units. Proper calibration isn’t optional—it’s per-device.

    I also looked at how #Meshtastic handles the onboard #QMC6310… and it essentially doesn’t (no heading, no calibration).

    "dispersed nature of #smartgrids, with thousands of interconnected devices like #smartmeters, #sensors, and distributed energy resources #DER's, creates a vast attack surface. For #substations, many operate #legacysystems (such as supervisory control and data acquisition #SCADA, which are essential for monitoring and control, and are prime targets."

    I don't get what happened with that markdown table either.

  7. I finally finished building and documenting 3 projects for with or . These apps display both on device and in CLI (using Python ). And yes, these apps are totally 🤓
