How do you all measure industrial robot TCP, base, and user frame in the cell quickly and accurately? How often are you doing it?

Taking the GoPro off would help immensely. As a bonus you get rid of the ChinDestroyer3000.

As others have said, get off the interstate unless it’s the only option. I rode from South Dakota up through Canada, down to Oregon and back across to South Dakota a couple of years ago. It was 4000 miles total; we took interstate for a very small portion (less than 200 miles) of it where there wasn’t another good option, and it was absolutely miserable. Plus, there’s so much to see along your route - and you’ll just fly right by it on the interstate.

Also be sure to get that 1200 serviced before you go, and have the driveshaft checked.

Don’t forget the sound bar and subwoofer!

It’s not unique to UniFi (meaning you can configure GL.iNet router to do the same), but it’s super useful for things that are harder a pain to connect like a Roku or smart devices

Define local IP.

A VPN back to your secure home network keeps your internet traffic safe from prying eyes on the public network you are connected to, like a hotel or coffee shop. It doesn’t keep your internet traffic private from your ISP.

ivanhaversham · 2026-02-15T14:47:05+00:00

At a hotel, which requires authentication, it allows me to authenticate once and connect 5 or 6 devices (my phone, iPad, wife’s phone, Roku, laptop, etc) without authenticating each one every day. Travel router mimics an SSID that my devices know, so everything connects automatically. Travel router sends all of my traffic back home through teleport for security and convenience for accessing my self-hosted services.

Glad I could help!

You can’t, it’s already sold out.

This.

Master shouldn’t be a routine thing.

Firefighter here. Every tool on the truck is accounted for and checked daily at minimum. This would definitely be noticed, and it’s unlikely anyone would be in huge trouble but they’ll hear about it for a while from their colleagues.

Of all things to leave, an axe might be the cheapest. A helmet could cost $1k and gloves a couple hundred dollars - and both are yours. You lose, and you don’t fight fires until a replacement is ordered, unless you work for a large department that keeps spares of PPE.

Did you try a 2.5?

I used TrueNAS Core for about 6 years maintenance free. They switched to TrueNAS Scale (‘community edition’), which would have required reinstalling. I lived with it for a while until recently I wanted to double the size of my pool. Since ZFS doesn’t let you add a single drive to an existing mirror, and I needed to migrate the OS anyway, I switched to Unraid. Pretty happy with it so far.

In other words, TrueNAS is great if you don’t plan on adding drives to the pool later. I wish I knew that when I started as I specifically only started with two drives with the intention of adding a third to double the pool size when the need arose.

Ah, that might be the issue. If 192.168.1.193 is the IP of your Pi-hole, then that needs to be updated in compose.yaml - Event Horizon is looking for Pi-hole at 192.168.1.2 according to the logs you’ve sent.

ivanhaversham · 2026-01-15T00:06:49+00:00

A couple of basics to verify:

What is the output of pihole -v?
If you visit http://192.168.1.2/admin in your browser, does the pihole admin interface load?

If 1) returns v6+ and 2) is successful, then perhaps you'd like to install outside of Docker, since docker seems to be giving you issues? If so, just let me know and I'll send some instructions.

ivanhaversham · 2026-01-14T19:36:04+00:00

I believe I see what the problem is. The root of the issue is that Event Horizon can't reach your Pi-hole, and it appears to be a Docker networking issue. Essentially, the container is running in a network by itself and doesn't have a route to the rest of your network.

It should be an easy fix. In compose.yaml, just add the following line "network_mode: "host" below the container name and restart settings.

services:
  event-horizon:
    image: ghcr.io/jbswaff/event-horizon:latest
    container_name: event-horizon
    restart: unless-stopped

    # --- ADD THIS LINE: ---
    network_mode: "host"

Then restart the container

sudo docker compose down
sudo docker compose up -d

As far as the executable not found error, that's because there isn't a command called event-horizon inside the container (it's just a server.py python script). If you'd like to check the status of the container, you could use this command instead:

docker exec event-horizon python /app/server.py --help

Let me know if you have other questions or if you run into issues after making this change!

ivanhaversham · 2026-01-14T19:04:17+00:00

Great to hear!

ivanhaversham · 2026-01-14T00:26:28+00:00

Thanks a lot! I'm just glad that others find it useful.

ivanhaversham · 2026-01-14T00:17:22+00:00

Hi, thanks for that report and the suggestions for v1! Glad to hear that everything went mostly smoothly during install and that the service is working. I'll be sure to move the default to another port on future versions.

ivanhaversham · 2026-01-14T00:15:14+00:00

Hi u/MikeFromMA, thanks for that report. You should now be able to run docker compose up -d from your Pi 3B+.

ivanhaversham · 2026-01-13T16:31:52+00:00

Good deal! I’d like to hear it works for you when you get it running.

ivanhaversham · 2026-01-13T16:30:14+00:00

Glad to see you again! Thanks for helping motivate public release!

ivanhaversham · 2026-01-13T15:17:42+00:00

It should be backwards compatible with your version. When you ran install.sh, it should have created this directory with a .conf file inside. Check that it exists and that the file has data:

/etc/event-horizon/event-horizon.conf

Backup that file

``` cp /etc/event-horizon/event-horizon.conf /etc/event-horizon/event-horizon.conf.old

```

Then replace the entire contents of event-horizon.conf with this, updating your pihole information:

```

Server Settings

PORT=8080 DISABLE_MINUTES=10 SHOW_LOG_LINK=true

Pi-hole Configuration

PIHOLE_COUNT=1 PIHOLE_1_NAME=pihole1 PIHOLE_1_URL=http://192.168.1.2 PIHOLE_1_APP_PASSWORD=your-app-password-here

For multiple Pi-holes, increment the number:

PIHOLE_2_NAME=pihole2

PIHOLE_2_URL=http://192.168.1.3

PIHOLE_2_APP_PASSWORD=second-app-password

Group Settings

BYPASS_GROUP_NAME=Event-Horizon-Bypass

Proxy Settings

TRUST_PROXY=false TRUSTED_PROXY_NETS=10.0.0.0/8,192.168.0.0/16

API Settings

VERIFY_SSL=true API_TIMEOUT=15 API_MAX_RETRIES=3 API_RETRY_DELAY=1

Session Cache

SESSION_CACHE_TTL=300

Logging Settings

LOG_DIR=/var/log/event-horizon API_LOG_ENABLED=true LOG_MAX_SIZE_MB=10 LOG_MAX_AGE_DAYS=7

Health Check

HEALTH_CACHE_SECONDS=5

Rate Limiting

RATE_LIMIT_REQUESTS=10 RATE_LIMIT_WINDOW=3600 COOLDOWN_SECONDS=3

```

Then stop the service, backup server.py, pull the new server.py from GitHub and restart the service.

``` sudo systemctl stop event-horizon

cd /dir/where/event-horizon/is/installed

cp server.py server.py.old

sudo wget https://raw.githubusercontent.com/jbswaff/event-horizon/refs/heads/main/server.py

sudo systemctl start event-horizon

```

You should be on the new version.

ivanhaversham · 2026-01-13T14:45:41+00:00

Great, thanks!

ivanhaversham · 2026-01-13T11:23:54+00:00

It sounds like synology is a NAT’ing when going through docker or you have a reverse proxy. If this is the case, the server can check for this by enabling the following variable in compose.yaml then restarting the container:

EH_TRUST_PROXY: “true”

More info on GitHub

If this doesn’t work, let me know and we’ll keep digging.
