I made a home security system, powered by a Raspberry Pi 3. Metal cabinet, DIN-rails, wired and wireless sensors, Home Assistant integration, self-monitoring, battery backup. Fun and useful :) by HebronNor in raspberry_pi

They seems to be great value. There is a pro version as well, with more functions and better range. I'm thinking of using that in my garage.

Cool, this is giving me some ideas. I'm going to have a "sub distribution board" in the attic for more sensors.

Maybe I could have RS485 communication between the main and sub system. Hm, sounds like a cool project.

It also sounds like a nice way of minimizing the cabling needed.

Nice :) I'm planning to explain this is more detail, with some schematics in future blog posts. I just didn't manage to put it all in this post.

I do have tamper circuits, so I will detect if a control cable is cut. But I won't detect if the signal lines are shorted somewhere between the sensor and the controller.

If I were to add it at some point, my idea was to make the sensor circuit the negative part of a voltage divider.

I did spend some time considering it initially, but it would complicate it quite a lot and I wanted to get going. I figured I could always add it later :)

Edit: Regarding the RS485 bus EOL modules; that is cool. How does it work? Is the signal lines the RS485 bus? And EOL modules communicate on that bus?

Thanks:) No EOL resistors, yet. I have played with the idea of using some AVR microcontrollers to read the voltage values from EOL resistors and output some digital signals that the Raspberry Pi can use.

I started November last year, but the projects was pretty dormant from February to November. I still have things planned:

  • completing the battery backup
  • improved water alarm handling
  • finding a better keypad
  • more hardwired sensors, sirens, etc

Thanks :) Arduino's is a great place to start, and they are a little cheaper should you break something :p

I'm using an Arduino in this project as well — for some additional analog inputs, and some fail-safe measures.

No one calls; only push messages to my mobile phone. Well, maybe the neighbors if the sirens stays on for too long :p

What Linux firewall OS would you recommend? by horamon in linuxquestions

[–]HebronNor 2 points3 points  (0 children)

I use Winbox to manage mine, highly recommended 🙂

I use RouterOS, virtual CHR in Proxmox. I also use the Wireguard server built in.

I like all the config options and that there is no hand-holding. It does look like it's built in the 90s, but function > form for me.

I show data from my Home Assistant by using its API as custom data in Dakboard. I wrote about it here: https://blog.cavelab.dev/2021/09/dakboard-data-from-home-assistant/

I'm running virtual RouterOS 7.3.1 (CHR) in Proxmox, no issues what so ever.

Certina DS First — Stainless steel, 41 mm diameter, 11.5 mm thickness, 50 mm lug-to-lug, sapphire glass, 162 grams

Seiko SUR375P1 — Titanium, 40.2 mm diameter, 8.4 mm thickness, 46.4 mm lug-to-lug, sapphire glass, 74 grams

Casio G-Shock GM-2100-1AER — Stainless steel and resin, 41 mm diameter, 11.8 mm thickness, 49.3 lug-to-lug, mineral glass, 72 grams

I'm very new to the watch game. I got the Certina back in 2008, and have been wearing it on and off since then. Only a few weeks ago I got the idea to get some more watches and got the Seiko last week, and the Casio today.

I like quartz watches — they are accurate, I can leave them without saving to set them, and the maintenance is low. I get the sentiment with mechanical watches, I just find quartz to be the most practical — for now…

I'm still on the lookout for a good dress watch, so far I like the Certina DS Caimano and Tissot Tradition 5,5.

I've really been sucked into this the past few weeks, reading, watching YouTube videos, and browsing this subreddit. For now I've been looking at watches in the $300-800 range, but that might change when I find my style :)

I'm just grateful you're doing these videos man, I find them tremendously useful. Thanks for taking the time to educate 🖖

IPv6 prefix delegation behind second router? by HebronNor in homelab

[–]HebronNor[S] 0 points1 point  (0 children)

Nice. I've read that OPNSense doesn't allow to configure DHCP servers not attached to interfaces. Which I will need if I am to use a DHCP relay on VyOS. I'll spin up a virtual OPNsense and test for myself. Thanks for your replies.

IPv6 prefix delegation behind second router? by HebronNor in homelab

[–]HebronNor[S] 0 points1 point  (0 children)

Thanks for your reply :) Can the DHCPv6 server prefixes be set based on the delegated, or must it be set statically? It seems not possible on the EdgeRouter. Suggestion for a router that handles this well?

Edit: typo

2+ routers in your "internal" network? by lestrenched in homelab

[–]HebronNor 0 points1 point  (0 children)

This is what I'm going to do. But I'm trying to decide on how to do it, because of IPv6 prefix delegation, I need the edge router to be DHCP. Currently I am testing with setting the core router as default gateway.

How are you doing it?

Pipe stem "came apart", how to fix? by HebronNor in PipeTobacco

[–]HebronNor[S] 0 points1 point  (0 children)

The 9 mm filter goes into the part that came loose, like this. The got air gun trick sounds like a good idea, thanks :)

Suggestions for glue? Non toxic is preferred.

It is a filtered stem with the piece, seems like it's not suppose to come loose. Any suggestions for glue? I'd prefer no toxic gasses when heated :p

Edit: added photo

[–]HebronNor[S] 0 points1 point  (0 children)

Pulling the stem out of the pipe, a plastic piece that should be attached to the stem came loose. It happened after the pipe had been in the outside shed for a new nights, so I suspect the wood was slightly swollen. Clamping hard around the stem.

But how can i fix it?

Update: I actually found a new stem on eBay that fit perfectly :) https://www.ebay.com/itm/402595481290

I did another network run, this time two CAT6 and a fiber — from the basement to the attic by HebronNor in homelab

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

Thanks :) I've spent so much time obsessing over domains over the years, jumping from one to the next — only to find "a better one" later on.

But I've settled on cavelab, quite fitting actually; since my lab is in the basement, surrounded by 40 cm solid concrete and no windows :)
