  • Posted wrong, here’s my whole story:

    I have a single AC damper that is fail-close, but was wired as always powered open by the people who put the AC unit into my house before I bought it. This would be fine, except I live near a meat packing plant, and sometimes the air outside stinks. I want to be able to close and open the damper based on various criteria I get from home assistant. (air quality, direction, speed, etc)

    This is the AC damper unit: https://www.resideo.com/us/en/pro/products/air/forced-air-zoning/replacement-actuators/replacement-motor-for-eard-ventilation-damper-m847d-vent-u/

    This is the shelly plus uni im trying to use: https://us.shelly.com/products/shelly-plus-uni

    And the multimeter says the output power for the damper (which is powered by my AC unit) outputs 30V AC power.

    I was able to power the shelly device by just plugging it into the AC power with Red to Red, and Black to Black. However, it turns out the Shelly device does not send that power out through its two switchable outputs. Those are called “dry circuits” apparently.

    So my goal is to power the shelly device, the ac damper device, and have the shelly device ALSO switch the damper on and off. I know it’s possible, I just don’t know how.

    So, the above diagram is my attempt to wire the shelly device into the setup. However, whenever I power the relay in the shelly device, the shelly device fries itself. So I’m looking for where I went wrong, and how to make it all work.



  • I know most of the less expensive used hardware is going to be server-shaped/rackmount. Don’t go for it unless you have a garage or shed that you can stuff them in. They put out jet-engine levels of noise and require god tier soundproofing in order to quiet them. The ones that are advertised as quiet are quiet as compared to other server hardware.

    You can grab an epyc motherboard that is ATX and will do all you want, and can then move it to a rackmount later if you end up going that way.

    The NVIDIA launch has been a bit of a paper one. I don’t expect the prices of anything else to adjust down, rather the 5090 may just end up adjusting itself up. This may change over time, but the next couple of months aren’t likely to have major deals worth holding out for.


  • Just think of your point that they are using residential IP addresses. How do they get these addresses?

    You can ping all of the ipv4 addresses in under an hour. If all you’re looking for is publicly available words written by people, you only have to poke port 80 and then suddenly you have practically every possible small self-hosted website out there.


  • I have the previous model. It does a great job of playing videos from my server in the other room. It technically can do YouTube, but that’s a pretty horrible experience. It can’t do any other paid streaming services.

    But it does do an amazing job of local streaming. It handles most all of the audio and video codecs, and can direct stream just about any video file without too much playing around. I like mine, and definitely recommend it for anyone who also wants a trustworthy local media player.

    Finally someone agrees with me. I swear it felt like I was the only sane person around. The curved edges made no sense design, use, or otherwise.

    I managed to mostly skip that BS by going with phones that didn’t use it, but I still had the occasional misstep whenever using someone else’s phone to check out their photo or whatever.

    Frankly, I’m happy to see it become less mainstream.
