Sander: Updated link to our Mastodon, to be a direct link.

This is the information page about how to reach us and how to find us. 

== Location ==

=== Address ===
The space is located at the shared office space in Concordiastraat 68, 3551 EM Utrecht. The building can be found by its name "Concordia Creative Industries Building".

Be sure to continue to the '''back parking lot''' of the building, there you can find the red entrance that is regularly used to get into the building. We're located in room 126

=== Randomdata open or closed? Check the [[Keymasters]] ===
The space is regularly open on Tuesdays from 19:00 till 21:00, unless it is a holiday.

Besides that you can keep track on [https://www.meetup.com/Randomdata/?eventOrigin=home_groups_you_organize the meetup] if there is any event happening at the space, like a CTF friday!

Outside of these times you can still visit the space, but only if one of the [[Keymasters]] is at the space.

=== Parking ===
There is free parking available at the space, you can park up front or in the back parking lot.

== Contact information ==
Here you can find our contact details, the higher up in this list the more frequently the communication channel is used by the community!

=== Signal ===
At random data we like our privacy and understand how important this is. That's why we are piloting with alternative communication platforms that keeps privacy-by-design in mind and respects our privacy. One of the most common fallacies is the argument that you have nothing to hide—because everyone has something to hide. After all, you wouldn’t post your social security number online either. Right now we have a pilot running with Signal as our main communication channel. For an invite, see discord channel.

=== Mastodon ===
We have an account on Mastodon! reach us at [https://hsnl.social/@randomdata @randomdata@hsnl.nl]

=== Mattermost ===
Randomdata is also active on Mattermost. This is a self hosted server by RandomData and offers an user friendly community platform to work together on space projects, gaming a security stuff and much more.

=== Meetup ===
The [https://www.meetup.com/randomdata/?eventOrigin=event_home_page meetup] is mainly used to track events planned by the space, but for brevity its added here as well because its possible to reach us from there, but expect a delayed response compared to other communication channels

=== Discord ===
There is a Discord available for RandomData but we aren't there much anymore, you can join it trough the link [https://discord.com/invite/9dzUnxF here]

== Legacy communication ==
While we do have these other methods of communication, Randomdata isn't as active on them compared to the previous section.

For clarity this section still lists these other communication channels.

=== WhatsApp ===
There was a WhatsApp community for Randomdata but we moved to Signal and our own mattermost because Meta/facebook/whatsapp is not privacy friendly. Want to know more?

=== Twitter ===

Sander: Initial version of the space state method we have.

==== Goals ====
On our website and [https://hackerspaces.nl/ hackerspaces.nl] we wanted to easily communicate with the outside world whether or not our hackerspace was open or not. There are a lot of (complicated) ways to do this, for example, detect movement with a webcam, regularly scan Bluetooth / WiFi for active devices etc. etc. However, I personally subscribe to the philosophy of K.I.S.S. (Keep It Stupidly Simple), so I've decided to do something with a simple on/off switch mounted on the wall where people can just easily say "space is open" or "space is closed" like this:

<TODO Picture of the box mounted on the wall>

That switch can easily be hooked into HomeAssistant using ESPHome on an ESP8266 development board which then controls the SpaceAPI integration. Normally that should be it, however we have one issue.. Our internet is behind a double NAT, which makes it a royal PITA. However, there are solutions for that.

==== Hardware used ====
1x ESP8266 Development board

1x Dead simple on/off switch

1x 3D printed box

==== Software used ====

* HomeAssistant with the [https://www.home-assistant.io/integrations/spaceapi/ SpaceAPI integration]
* ESPHome

==== Implementation ====
<Insert little spiel about our double nat situation etc etc>

===== HomeAssistant configuration =====
<TODO>

===== ESPHome configuration YAML =====
<TODO>

===== Double NAT workaround =====

====== Changelog: ======

* 05-09-2025: Initial version
