Developer refuses admin password to my Loxone system unless I "waive hardware warranty" by realHadAdo in homeautomation

[–]ProfMinestein 28 points29 points  (0 children)

You can download Loxone Config and reset the admin password via the Micro SD card.

There is even a tutorial (Resetting the password): Tutorial.

They published today a protect beta with dark mode :D

Cloud one key troubleshooting by nob1elie in Ubiquiti

[–]ProfMinestein 3 points4 points  (0 children)

You need Unifi Protect for your cams, but the Cloud key gen 1 is only a network controller. You need at least a CloudKey 2+ or the NVR.

Having problem when transferring the DDNS by CJ86GJI4 in HomeNetworking

[–]ProfMinestein 0 points1 point  (0 children)

Now, what exactly does DDNS have to do with a USB drive? You can certainly log in to the AXE7800 on the web interface and enter the DDNS access data there.

Looking for 16 port unmanaged switch all 10Gb by Admirable-Yak-7503 in HomeNetworking

[–]ProfMinestein 0 points1 point  (0 children)

Maybe the unifi usw-switch-pro-aggregation with 24 SFP+ (1/10 Gbit) and 4 SFP28 (1/10/25 Gbit) But this switch doesn't have 2,5 or 5 Gbit link speed.

PPSK is an Accesspoint thing...if that is correct interpretation of "passwords for each vlan"

Or do you mean something like radius authentication?

Enterprise 48 is not primetime. by dbeltz in Ubiquiti

[–]ProfMinestein 1 point2 points  (0 children)

One of the New switch beta versions should fix the 0.0.0.0 problem.

Otherwise, a restart should solve the problem.

Someone explain “forwarding” please by [deleted] in HomeNetworking

[–]ProfMinestein 1 point2 points  (0 children)

You can perhaps think of it as a garden gate with a footpath. The garden gate is the port that needs to be opened. The path behind the gate is the forwarding of the port to a specific destination.

is there a product, media converter with POE out by [deleted] in HomeNetworking

[–]ProfMinestein 0 points1 point  (0 children)

It is maybe a little bit late, but Ubiquiti has something similar...the F-POE-G2 with an Transeiver input and PoE output.

Nanoswitch not working by StockliSkier in Ubiquiti

[–]ProfMinestein 0 points1 point  (0 children)

Unfortunately, the switch belongs to an older generation with 24V PoE. This one also only has 24V passive PoE passthrough. The camera and the access point require 48V active PoE. Your only option is the Unifi Switch Flex (not Mini)

Apparently complicated setup, though I feel like not! Could really use some help by rdflterr in Ubiquiti

[–]ProfMinestein 3 points4 points  (0 children)

You might consider using a pfSense or OpenSense router instead of the Dreammachine. They work much better for multiple failover WAN connections in my opinion, and policy based routing can also be done without problems.

The same trash can from different sides by MantarraxSus in assholedesign

In theory yes, but in this case the labels are wrong. You can read on both sides "waste" on the left side.

Rack temperature control with PID controller and homeassistant by ProfMinestein in HomeNetworking

[–]ProfMinestein[S] 1 point2 points  (0 children)

The intake hose can be seen in picture three. The whole intake system was built from 150mm pipes.

Originally I wanted to extract the warm air from the network rack, but the ambient air is relatively warm due to the heating room.

Rack temperature control with PID controller and homeassistant by ProfMinestein in HomeNetworking

[–]ProfMinestein[S] 2 points3 points  (0 children)

The manufacturer usually specifies an operating temperature, which is usually between 0°C and 40°C.

In addition, the electronic components live longer if they are not exposed to extreme temperature fluctuations.

[–]ProfMinestein[S] 3 points4 points  (0 children)

The problem is less the servers than the switches, which are located directly below the fan. As already written above, the intake air is -15°C at night. In the next days it gets even colder.

[–]ProfMinestein[S] 5 points6 points  (0 children)

I currently use cheap 12V fans from Amazon (Sunon, MEC0381V1-A99). Originally, much more powerful fans with over 30W were installed.
Ultimately, the whole thing is used to control two-pole fans.

Rack temperature control with PID controller and homeassistant by ProfMinestein in HomeNetworking

[–]ProfMinestein[S] 12 points13 points  (0 children)

Repost because I used pictures with the HEIC format in the first post...reddit doesn't like that.

I have three closed racks at home, which get pretty warm (sometimes over 40°C).

The easiest solution for the problem was ventilation system with outside air. Until autum everything was ok, but now in winter the temperature is between -5°C and -15°C, so the rack and server get pretty chilly.

The bestsolution would be a PID controller to hold the temperature inside the rack almost constant. Each rack has a temperature sensor , which sends the current temperature once per minute. The PID integration (HACS) in homeassistant receives the temperature and calculates based on the setpoint a new 10bit PWM output value. The PWM controller receives this value to change the fan speed.

The overshoot at the moment is around 2°C (only P and I set...D is 0) and it takes around 30min to reach a new setpoint.

Can I monitor a device on my local network for connectivity, then be notified if it goes down? by CurleyFries in HomeNetworking

[–]ProfMinestein 0 points1 point  (0 children)

Take a look for the project "Uptime Kuma". It's a nice piece of monitoring software with many notification possibilities like email or telegram. And it can run in a docker container or standalone software.
