  • A while back I made a Lolin32-based weather station that lasts for around 60 days on a single disposable vape battery.

    It wakes up every 15 mins, and while it’s connecting to WiFi it retrieves the AM2302 sensor readings. As soon as they’re transmitted it goes back to sleep.

    I wish there was a more power efficient alternative though, like whatever is being used in those BLE LYWSD03MMC sensors that last for around 3-6 months on a cr2032 whilst also having a display built in



  • To combine a bunch of explanations I’ve seen in the comments here:

    A bourgeois philanthropist game show producer who dabbles in poverty porn.

    That said, I do occasionally burn time watching some of his videos, however some of the content (especially the more recent game show ones which feel a bit like toying with people) rub me the wrong way.

    I have no idea if his philanthropy efforts are genuine or not - he’s barely visible in those videos (he has another individual hosting those videos) although I do appreciate the efforts they appear to go to when assisting communities desperately in need, and careful implementation of solutions that are sustainable, and can actually be maintained and fixed with local knowledge.

    I’ve seen way too many “gimmicky” charity contributions by other organizations that become worthless as soon as they break because nobody fixes them, as well as other solutions that seemingly make sense from a western cultural lens but aren’t really understood by the local people… worst one being a “merry-go-round” water pump mechanism where senior locals are forced to “play” just to pump water for survival. It was originally intended as a kids toy, but they of course don’t have any attachment to such a foreign device, thus don’t use it.

    Ehhh apologies for the mini rant there 😅





  • ASMedia is the only controller IC manufacturer that can be trusted for these IME. They also have the best Linux support compared to the other options and support pass-through commands. These are commonly found in USB DAS enclosures, and a very small fraction of single disk SATA enclosures

    Innostor controllers max out at SATA 2 and lock up when you issue pass-through commands (e.g. to read SMART data). These also return an incorrect serial number. These are commonly found in ultra cheap desktop hard drive docks, and 40pin IDE/44pin IDE/SATA to USB converters

    JMicron controllers (not affiliated with the reputable Micron) should be avoided unless you know what you are doing… UASP is flaky, and there are hacky kernel boot time parameters required to get these working on Raspberry Pi boards. Unfortunately these are the most popular ones on the market due to very low cost






  • I used to use MQTT, static_status and Healthchecks.io, and have that data passed through to Home Assistant, but it started to get pretty cumbersome as the amount of machines I had grew.

    I now use just Zabbix and HealthchecksIO. I did need to spend some time writing new templates for some additional data I wanted to collect (like SMART data for SSDs that provide health metrics in non-standard attributes, and HealthchecksIO so I could see the status of various checks on my zabbix dashboard)

    Zabbix also has some additional features I found appealing, like proxies that can continue recording data when the main server is down, and built in encryption. Some checks like open ports/icmp responses etc can be checked using either the local agent, the remote server, or both, which helps quickly diagnose things like firewall config issues.

    I did look at some other solutions, but I wanted something integrated to hit the ground running. Mobile apps are very limited, and there is no official one to my knowledge. I use Moobix which I don’t believe is FOSS - but I could be wrong there

    Try each solution out and see what works best for you!
