  • Sorry but the theoretical price of cells isn’t relevant to the consumer. The price of products containing them is. This thing costs currently on the official site 900€ (with some sort of sale going on). The Elite 100v2 with comparable capacity, but using LiFePo4 (included in the same current sale) costs just 550€. To add insult to injury, it also outperforms the Na model in nearly every aspect except sub-freezing performance (where it at least still works, but nowhere near normal spec values either). This includes an abysmal solar charging efficiency for the Na of roughly 50% at normal temperature. Somehow.

    Again, once the price reflects the cell cost, this could be a very attractive option. At the moment, unless you’re into camping in sun-zero climates, it’s just a very bad deal.

    Edit: to be clear the Na model also doesn’t have a better life expectancy, not according to the spec. Both models are specified to “over 4000 cycles”, not there is no percentage threshold specified for the Na model. The LiFePo4 model includes “to 80% capacity” in that definition. If this is specified somewhere for the Na model, I can’t find it.


  • The thing currently costs at least 50% more than the closest equivalent LiFePo4 from the same brand. The only real advantage seems to be it’s ability to handle sub freezing temperatures, but usability still drops dramatically (both capacity and available power delivery). Everything else is straight up worse in this one in direct comparison.

    It’s only the first product, so it’ll most certainly get better. Also as numbers of products sold rise, costs fall. Once these are cheaper, that are a real choice.






  • The critical thing with these is response time. If it’s even slightly too high (I think 20-30ms is easily too high), some/many people get very motion sick. Getting that time down as low as needed is also not trivial.

    With it only being 60 Hz on the controller itself, that’s basically impossible to hit. That’s 16.6 ms already. Then the processing, sending to the PC, and the PC reacting has a budget of just a few ms? Yea, not happening.

    I’m assuming he’s really not sensitive to this. As it’s open source now the people who are sensitive can improve it. That’s the beauty of open source after all.





  • Just because it’s a “smart” service doesn’t mean it has to connect to the Internet or a server or the manufacturer. If it does neither, it can’t be turned off by them.

    All my devices run local-only protocols. Nothing leaves my house. The devices that would be proprietary were reflashed to tasmota (fully open source, local only). Others are either Zigbee or Shelly. While Shelly has a cloud connection, it’s fully optional and disabled by default (including automatic updates). The hardware is also supported by tasmota, and reflashing is always just 5 minutes of effort away.

    There is absolutely nothing that any manufacturer has to do to keep my stuff working. I have to do a little something (keep my tiny server on, basically). But more importantly there is nothing any manufacturer can do to stop my stuff from working.




  • While it’s fantastic software, it’s probably a relative cannon to shoot at his problem. Maybe there’s a way around this, but I’ve found the necessary management, curation and bookkeeping that was necessary for it too be useful to be just way too much to be worth it. I mean it’s fun for some, including me to a degree, but not too this extent.
