You already looked at https://wiki.nixos.org/wiki/Home-assistant , right? Yes, this certainly helps but for many things not listed there the correct way to implement it still is mostly trial and error as all tutorials depend on the GUI. | 01:08:21 |
| Lyn (they/she) | now I know better but i probably spent a day trying to figure out how to declare MQTT | 01:11:05 |
 Sandro 🐧 | Yeah, didn't get that much better with the latest updates, some things actually got worse | 01:11:16 |
| Lyn (they/she) | * | 01:11:32 |
| Sandro 🐧 | I usually tinker with GUI and copy things from there as previously said | 01:11:36 |
 @hexa:lossy.network | mqtt in yaml was removed | 01:11:50 |

mqtt in yaml was removed yeah :( | 01:12:05 |
 kdn | So... I'm getting a bunch of PWM 8x controllable fans for my RACK, is there a way to control those using raspberry pi and power from AC? | 11:18:45 |
 K900 | Well you'd need to get 12V or 5V or whatever the fans run at off the wall | 11:19:44 |
| K900 | And then in most cases you can just shove a PWM signal from the RPi into the fans | 11:20:00 |
| kdn | I'm not sure what kind of device(s) should I get | 11:20:05 |
| K900 | Most fans are perfectly fine with basically any level of PWM signal | 11:20:28 |
| K900 | A device for what? | 11:20:38 |
| kdn | to join those 8 together, power and adjust their speeds | 11:20:55 |
| kdn | preferably in 2 groups of 4 | 11:21:06 |
| K900 | Are they daisy chainable? | 11:21:57 |
| K900 | Can you link the fan model, actually? | 11:22:05 |
| kdn | https://www.arctic.de/en/P14-PWM-PST-CO/ACFAN00126A | 11:22:12 |
| kdn | i see mostly 2.5A LED power supplies for PWM | 11:23:47 |
| K900 | Yeah those daisy chain | 11:23:53 |
| K900 | And are 12V | 11:24:16 |
| K900 | So if you can get a 12V source, you can jank something together pretty easily | 11:24:30 |
| K900 | You basically just run 12V to the power pins | 11:25:23 |
| K900 | And then a PWM signal from an RPi or whatever to the PWM pin | 11:25:44 |
| K900 | But also if any of your machines have a 4-pin fan header | 11:26:02 |
| K900 | Which is very likely as those things are bog standard | 11:26:09 |
| K900 | You should probably just use that | 11:26:16 |
| kdn | they definitely do | 11:26:22 |
| kdn | so plug directly into some mobos in 2 daisy chain groups instead of getting any extra equipment? | 11:26:58 |
| K900 | Yes | 11:27:41 |
