In a forest, away from humans, under trees, you won’t have a signal to send SMSs or get a data connection either.

It’s not, it’s just that forests are really bad for phone signals. Trees disrupting the signal, valleys and sides of mountains with no direct view of antennas and just remoteness in general. I’ve been in a lot of forests with no cell reception, that’s why you always go with an offline map and tell someone where you are going.

It’s not a case that one of the leading phone company in the world has a satellite emergency mode.

While videogames are great, a hobby that dabbles with real things will stimulate you very differently. Touching stuff with your hands, the gap between what you want and what comes out of your work, the search for materials and techniques and other aspects of working with real stuff and not on predefined paths, will engage with your brain in a very different way.

Videogames and “real” hobbies (as in hobbies that use real stuff) are great together in my opinion, they complement and fuel each other.

I connected my sectional garage door using a Shelly 1, an Aqara vibration sensor and the contact sensor from my alarm system (but you can use an Aqara door sensor), using Home Assistant to create a “virtual” door that does all the things.

Put the vibration sensor around the bottom of the door. Connect the Shelly to the hardware button you have somewhere in your garage, set it to toggle off after 1 second (simulating a button click basically). In Home Assistant do something like this:

<span style="color:#323232;">- platform: template
</span><span style="color:#323232;">  covers:
</span><span style="color:#323232;">    garage_door:
</span><span style="color:#323232;">      device_class: garage
</span><span style="color:#323232;">      friendly_name: "Garage Door"
</span><span style="color:#323232;">      value_template: >-
</span><span style="color:#323232;">        {% if is_state( "binary_sensor.garage_door_contact_sensor", "off") %}
</span><span style="color:#323232;">          closed
</span><span style="color:#323232;">        {% elif states( "sensor.garage_door_vibration_sensor_angle_y") | int &lt; 10 %}
</span><span style="color:#323232;">          open
</span><span style="color:#323232;">        {% elif is_state( "binary_sensor.garage_door_vibration_sensor_vibration", "on") %}
</span><span style="color:#323232;">          opening
</span><span style="color:#323232;">        {% else %}
</span><span style="color:#323232;">          open
</span><span style="color:#323232;">        {%- endif %}
</span><span style="color:#323232;">      open_cover:
</span><span style="color:#323232;">        service: script.disarm_alarm_if_armed_then_open_garage_door
</span><span style="color:#323232;">      close_cover:
</span><span style="color:#323232;">        service: switch.turn_on
</span><span style="color:#323232;">        data:
</span><span style="color:#323232;">          entity_id: switch.garage_door_shelly_1
</span><span style="color:#323232;">      stop_cover:
</span><span style="color:#323232;">        service: switch.turn_on
</span><span style="color:#323232;">        data:
</span><span style="color:#323232;">          entity_id: switch.garage_door_shelly_1
</span><span style="color:#323232;">      icon_template: >-
</span><span style="color:#323232;">        {% if is_state( "binary_sensor.garage_door_contact_sensor", "off") %}
</span><span style="color:#323232;">          mdi:garage
</span><span style="color:#323232;">        {% elif states( "sensor.garage_door_vibration_sensor_angle_y") | int &lt; 10 %}
</span><span style="color:#323232;">          mdi:garage-open
</span><span style="color:#323232;">        {% elif is_state( "binary_sensor.garage_door_vibration_sensor_vibration", "on") %}
</span><span style="color:#323232;">          mdi:garage-alert
</span><span style="color:#323232;">        {% else %}
</span><span style="color:#323232;">          mdi:garage-open
</span><span style="color:#323232;">        {%- endif %}
</span>

Basically if the contact sensor is off (means there is contact), the door is closed. If the vibration sensor angle is < 10 (check your values, this works for me), the door is open (the sections are now horizontal). If the vibration sensor senses vibrations, the door is currently moving. Otherwise report “open”, because that’s the worst state and if something doesn’t work, I want the worst state to be reported. Now you have a “cover”, which in Home Assistant is a class that has custom UIs and logic to handle the door. Whenever I click the open button or call the command from anywhere, “disarm_alarm_if_armed_then_open_garage_door” is called, meaning I can’t make the alarm go off by accident.

I have an automation that when I get near my house, it checks if my alarm is on and sends me a notification with 2 actions:

• disarm alarm
• disarm alarm and open garage door

PS: Looking back at my code, I should add a condition to both “open_cover” and “close_cover”, to check if the door is opening, making it fail (or just do nothing), because while moving, pressing the button would stop the door, not make it go in the reverse direction. But it’s been 4 months with this integration and it works great.

I got my PS2, with GTA3, for Xmas. No memory card though, so I stayed up all night to play it, not realizing I could just left it on. I bought the memory card 3 days later, when shops reopened, the PS2 was never shut down.

The fine was 1b, 10 years ago. Nowadays chips have a geopolitical importance, so they lowered the fine to keep one of the most important player happy. Intel is finalizing contracts for billions here in Europe to build chip factories.

This was a smart political move, not a mathematical operation

I used to use Octoprint to connect to an Ender 3, which didn’t come with an internet connection. Now that I have an Ankermake M5, I don’t use it anymore.

You could connect your desktop to the 3D printer, I don’t think a Raspberry is required.

Due settimane fa ho giocato la mia balena bianca, Twilight Imperium. Partita in 5, con i condizionatori rotti, 35 gradi nella stanza, dalle 9 di mattina alle 9 di sera (smesso per mancanza di luce). Era nella scatola da 1 anno. Mi considero soddisfatto, tutti i giochini nella pile of shame (comunque pochi) sono dimenticati ora

ONVIF needs a user with username and password, you will need at least a web interface to add it to the camera. What’s the problem with a web app hosted by the camera?

Non ci sono per ora funzionalità di spostamento account su altre istanze, ma nella pagina github di Lemmy ci sono diverse discussioni a riguardo.

Per quanto riguarda post e messaggi, credo che sia tutto copiato su tutti i server federati con feddit.it, quindi almeno i byte sono copiati altrove (ma ho in mente che le copie durino 6 mesi, forse l'ho letto da qualche parte). Poi non so se il protocollo prevede il poter leggere questi post anche se il server originale non è disponibile (direi di si tecnicamente, ma va a capire che regole ci sono dentro)

I'm an Android developer, I usually spot a non native app immediately and the flaws in the ui are really annoying. Web apps are even worse.

What I am not understanding is the concept of logging in another server. I created an account on feddit.it, can I use this account to login in a mastodon website? Or does it work the other way around, with me just using the feddit.it website (like I’m doing right now) to consume content from other instances? With the second option, if feddit.it goes down, my account is done, right?
