  • Lots of things can be hooked up through it. One of the biggest things I find I like about it is the way you can merge ecosystems with it.

    At home with HA I have an LG TV, Philips Hue lights, a Tapo vacuum cleaner, my EV charger, my own home made solar hot water system controller, a presence sensor that also does CO2 and temperature, a hot tub, and a few other bits and pieces. All of which can be viewed and controlled in the one interface, not the 6 or 7 apps that every individual device wants me to install.

    But automations and notifications are the big thing. The presence sensor in the living room turns off the tv if nobody is in front of it for more than an hour. The EV charger tells me when the car is charged. An hour before sunset the light in my living room slowly dims on, and dims off after 9pm when the presence sensor says there’s nobody around. When my solar hot water system is a bit slow to heat up on a cloudy day, I get an email telling me to turn the electric booster on (and off when the water’s hot). Every Tuesday and Thursday evening the vacuum cleaner is set to clean the living areas, but it doesn’t if someone is watching tv, as detected by the presence sensor and the television.

    I also don’t have to get off the couch to turn on a light, but the idea is that you set up automations that do all the button-pressing for you.





  • But it’s definitely not perfect and tends to add unnecessary changes, I constantly have to review and add new rules.

    This is the bit that bugs me. I spend a bit of time to create a relatively simple application in C# with it, and it’s constantly tacking on new features and four extra command line arguments and it’s frothing at the mouth to add Cool Feature X, “just say the word and I’ll do it”.

    Just do what I asked. No more. That’s enough. There’s enough mangled code and logic errors lurking in there already, I don’t need any more “features” clouding the water.




  • I’ve worked in mines in the desert in South Australia where temps semi regularly hit 46-47 degrees.

    It’s OK (ish) because the humidity is low. But you can drink a litre an hour all day (11+ hours) and not need to pee. All that water goes somewhere.

    The underground workings are often more dangerous, with lower temperatures but higher humidity. Once wet bulb temps get above 34 degrees underground personnel need to retreat from the area and the only work that can be done there then is work to fix the ventilation.

    There’s heat stress meters that measure wet and dry bulb temperatures and airflow, and can basically compute cooling power in watts. Not enough cooling power -> everyone out.

    Maxbotix make robust ultrasonic sensors that range out to 6m, they have a 3/4" pipe fitting on the back for mounting them.

    So with that you can get a few lengths of 3/4" pipe and an elbow and have an easy way of mounting it a little ways into your well.

    A little on the expensive side but simple to use and easy to weatherproof.






  • Are you doing chmod with the recursive option? You could list a few subfolders with “ls -la” and see who owns them and what permissions they have.

    It’s also possible that your distribution mounts that drive with fixed permissions that override whatever you’re trying to set. Checking with “mount” and seeing what it spits out for the mount options for that device might give a clue.
