  • I’ve found the same thing with regard to workflow - I find it really weird when people say it’s nothing like any other CAD programs, because it really is. You start with sketches and build up from there. Yes, the spreadsheet feature is amazing! I couldn’t believe SolidWorks forces you to buy Excel to do the same thing, which is crazy. The spreadsheet integration in FreeCAD is great - with the macro that handles the reference labels.

    I finally realised how freecad wants me to use it and found it much nicer to work with after that

    Exactly this - once people invest the time to understand the FreeCAD flow, and get over it, they’ll find it’s an amazing and extremely productive tool.

    I tried out SolidWorks and it’s a complete mess. You can’t just download and install it, it runs a bunch of weird background programs on the computer, and interacting with the multiple web sites is a nightmare. I’ve been waiting well over a month for them to refund under the promised 30 day guarantee. I’d never, ever do anything with that awful company again.

    I’m really looking forward to see how Ondsel does. I’ve been using it for the last week or two, as it’s integrated 0.22 features, and I think it could be a really good thing for the FreeCAD community.


  • Strongly disagree. There’s nothing I can do in any of the commercial CAD programs that I can’t do in FreeCAD. Most people just don’t want to invest the time to learn it - and instead blame the tool. Yes, there’s a learning curve and it requires understanding the tool’s limitations, but if it wasn’t for FreeCAD we’d have nothing in the free, open source space for CAD.



  • I don’t have an exact answer to your problem, but I do have a few ideas to think about. I’ve got a few ESP32 WROOM boards running in various applications, so I’m a bit familiar. So here’s my thoughts:

    • I only plug the module into data USB (computer) for the initial firmware provisioning. After that, it’s 100% wifi and USB is only for power using a power supply, not the computer. And I do the initial provisioning with just the bare ESP32 - no breakout board, nothing plugged into GPIO. Get the device up on wifi with NO other configuration in the firmware.
    • I use the “arduino” framework. I don’t know if that’s correct or really matters, I’ve heard it’s the same as “esp32dev” but I don’t really know. I use “arduino” because that’s what the examples used when I setup my first board.
    • Is it possible that the sensor module/board is using the same GPIO that the USB UART uses? There is a lot of shared usage of the GPIO that you’ve got to be careful to work around. The dev tools will often catch this when you compile your firmware, but not always. Again, using wifi after the initial provisioning might be enough if it is sharing GPIO with the serial port.
    • If you repower the ESP32 too many times rapidly it’ll boot into safe mode. You can change the settings on that, but you can also just work slowly - make sure the device is powered on for a few minutes to record a good boot in the flash. It outputs a message in the logs, so it’s handy to always be running the log command in a terminal while developing.

    Hope that helps! They are a lot of fun to integrate with HA.


  • Same here. Useful breakdown on tools, several of which I’ve used. I’ve invested a lot of time in FreeCAD thus far, and as I’ve learned how to do things with the right workflow to prevent errors it’s really quite nice and very powerful - and it will continue to only get better with each release. Fortunately, there are great videos and posts when I do get stuck. I can’t say enough good things about MangoJellys YouTube videos in learning how to do things the FreeCAD way - probably half of FreeCAD I’d never learn to use by just clicking around. I intend to continue down this road too, and have donated to the FreeCAD project and supported creators versus paying for commercial software. No regrets!

    Nope - that’s the whole point of ZFS - you don’t need any special hardware, nor do you want that layer hiding the details since ZFS manages the drives. Plus, you probably want to use RAIDZx with spare drives to absorb failure.




  • Strange! Nothing jumps out at me as being an obvious problem with your setup. I’m doing something similar, though instead of rtlamr2mqtt (which I didn’t know about) I have a bash script run via cron that parses rtlamr output via jq and pipes that to mqtt (mosquitto), but there’s very little to it. I know the energy dashboard setup is picky about the energy recording entities.

    Mine looks like:

    state_class: total_increasing
    unit_of_measurement: ft³
    device_class: gas
    friendly_name: Gas Meter
    

    The name of the entity is sensor.gas_meter and the state is currently 113812 as an example.

    Might be worth reading through GitHub issues for rtlamr2mqtt, including closed ones, if you haven’t already. Or maybe a hass restart? Can’t think of anything else.
