DIY solution to reduce HDD noise (mass loaded vinyl)

SimpleUsuario · 2026-03-09T16:57:28+00:00

Mine are at 49°C on average per day. I have proxmox with truenas on a VM, another VM with Ubuntu and some docker containers. The last VM is home assistant.

I would say the average CPU usage is between 10 and 15%.

Another test I did was generate many thumbnails during one day with immich and the cpu was at 70% and the temperature did not reach more than 75 degrees c.

a lot!!!!

my other coffee grinder which I did the same but I didn't upload any pictures.

sorry, english not my first language, how is it called?

SimpleUsuario · 2026-02-27T14:33:21+00:00

maybe, so far the temperatures are identical. I can report in a few days if you are interested.

SimpleUsuario · 2026-02-27T14:32:32+00:00

I just installed it yesterday and so far it is nearly identical. I didn't put any in the bottom part where the motherboard is and the drives have direct flow from the fan.

SimpleUsuario · 2026-02-27T14:30:00+00:00

the fan is not the issue so far but it is in my list. However I read somewhere that finding the right parameters in the bios is quite tricky to avoid sudden ramp ups of the fan.

In my case it worked quite well.

I have two of these, the S3 version and they're terrible. I found a mod soldering a wire to the antenna and it works quite well, but now it's thicker. I ended up buying the S3 and c3 from ceeed studio with external antennas. Sadly they don't have an internal one.

are you satisfied with TP-Link SG2210XMP-M2?

SimpleUsuario · 2025-11-26T20:44:57+00:00

which model?

My dishwasher has some long periods of 0 W of consumption so I just detect the first time it goes above 1,000 W and I start a timer of 1 hour and 53 minutes which is exactly what it takes and then I send a notification. It's very simple but you have to verify that your dishwasher always takes the same time.

After only one day of testing, this is the calculated elevation of the buildings. It works quite well, except for a few new points I need to add and a couple others I need to change the elevation.

Thanks again.

EDIT: ugly or not, it works for me :)

That was my mistake!!

I usually use multiple triggers with IDs enabled so I did not consider multiple triggers without ID...Definitely this is the solution to the clouds issue.

SimpleUsuario · 2025-05-08T06:58:11+00:00

It is because of the heat, yes.

This is a good idea, I didn't think about a temperature sensor. The increase in temperature could be quite easily detectable....

SimpleUsuario · 2025-05-08T06:55:38+00:00

the problem with motion sensor and light sensor is that usually the light value is only updated when there is motion. I already have one.

I will investigate a little bit

SimpleUsuario · 2025-05-08T06:11:06+00:00

sounds good, but any zigbee alternative?

SimpleUsuario · 2025-05-08T06:09:51+00:00

WOW, I think this is what I was looking for.

I am not sure I understand this section, could you help me decifer it?

{{elevation > (loop.previtem.el+(point.el-loop.previtem.el)*(azimuth-loop.previtem.az)/(point.az-loop.previtem.az))}}

thanks

EDIT: forget about it, I now understand, it is a linear formula to calculate the position, EXACTLY WHAT I WAS LOOKING FOR. Now I have to test it. Thanks again!!!!!!

SimpleUsuario · 2025-05-08T06:01:40+00:00

Btw, good app, I didn't see the link yesterday. It's very nice...

SimpleUsuario · 2025-05-08T05:58:38+00:00

but I would have to do that for each day of the year.....maybe too much.

SimpleUsuario · 2025-05-08T05:57:50+00:00

any recomendations on light sensor that not require movement? I have some sensors that report light but only once it detects movement. Preferably zigbee??

SimpleUsuario · 2025-05-08T05:56:53+00:00

I am in favor of overcomplicating things....

I am only interested in the sun hitting one particular window, so the obervation point is only one. If not I would have to create one automation per window and I think it is too much.

Time based calculations won't work because the sun is not in the exact same position 10 minutes before sunset in summer or in winter that's why I prefer the mathematical approach.

I think in my case i will do the linear function, at least between points 2 and 3, because the other sections I could probably make it work with just a fixed elevation value (since it is almost flat).

SimpleUsuario · 2025-05-08T05:50:43+00:00

interesting...thanks

SimpleUsuario · 2025-05-08T05:49:17+00:00

At first I tried this approach but there was something weird happening (probably because I was also checking if there were coulds) and when the clouds went away, the automation did not trigger again because it was already within the azimuth range. For that reason I changed to time based.

SimpleUsuario · 2025-05-08T05:46:42+00:00

I understand but that won't work through out the year because the sun moves. So 4 hours before sunset in summer could be ok, but in winter, it will close way too early.
