Remote access to Pi-Cloud

Sooner or later, you’ll want to access your Nextcloud remotely from the internet. Whether it’s to show photos to your loved ones, back something up while on vacation, or retrieve a contract stored in the Wiki, directly publishing Nextcloud to the internet may not be the best choice. We’ll show you how to achieve this using a secure and end-to-end encrypted connection. We’ll outline two options using the Wireguard VPN protocol.

What we’ll need

PiCloud - installation instructions can be found in the previous article

Getting Started

1) VPN (Virtual Private Network) without a public IP address

If you don’t have a public IP address at home and don’t want to pay for one from your internet provider, the easiest solution is the Tailscale service.

Tailscale is a software solution for creating virtual private networks (VPN) built on the WireGuard protocol. It allows users to easily connect devices, such as computers, servers, smartphones, and more, into a secure network that is protected against eavesdropping and external attacks. Tailscale simplifies VPN setup, which is traditionally considered complex and time-consuming.

Go to the Tailscale page (https://login.tailscale.com/) and create an account, or use an existing Google/Apple/GitHub account.

After logging in to the admin panel, go to Settings -> Key and generate a key for your Pi-Cloud.

Save the key, then log in to Casa OS, as described in the previous article on installing Casa OS and Nextcloud. In Casa OS, go to Apps -> Custom install.

Switch to the Docker CLI tab and enter the following script:

docker run -d --name=tailscaled -v /var/lib:/var/lib -v /dev/net/tun:/dev/net/tun --network=host --cap-add=NET_ADMIN --cap-add=NET_RAW tailscale/tailscale

Confirm, and you’ll get a prompt to fill in additional information. Mainly, enter the name, type, set to "latest," and don’t forget to manually add a key with the name TS_AUTHKEY

where you’ll paste the saved key from the Tailscale website.

Click install, and you’re done! Casa OS is now visible in the Tailscale device list.

You can then use this IP address to connect remotely, for example, from a phone. Be sure to add other devices to Tailscale that you want to use to access the network

apps are available for iOS, Android, and other platforms. For details, see our article Tailscale - access without a public IP address from the blog.

2) WireGuard with Public IP address

Tailscale - remote access without public IPRating: 90%

The Tailscale service solves access between individual devices if you don't have a public IP address. It's free for one user with support for up to 100 devices. We'll show you how to install Tailscale on a Raspberry Pi that you'll have at home and on a client (Android, iPhone) from which you'll want to access the home Raspberry Pi. Our example will be remote access to OpenHAB running on a Raspberry Pi. However, the same setup applies to many other applications - home NAS, PiHole, Home Assistant, Domoticz, NextCloud, and others.

Shelly vs OpenHABRating: 90%

The Shelly brand is known for its products that primarily communicate over WiFi, including smart plugs, relay switches, blinds control relays, and many other devices. One of the advantages for deployment is the ability to both read and control these devices using the universal MQTT protocol. Across existing add-ons for both OpenHAB and Home Assistant, we will demonstrate how to use Shelly devices without installing any additional extensions.

Victron vs Smart HomeRating: 0%

In this post, we will show you how to retrieve information from a photovoltaic power plant by Victron. We will connect to the Cerbo unit via MQTT. Based on these values, we can control various appliances (heating, boiler, etc.) and prevent the battery from being drained when they don't need to be.

Smart Home vs GoodWeRating: 50%

In the post, we will demonstrate step by step how to communicate directly with the GoodWe inverter in a smart home setup and obtain real-time information (unlike the SEMS portal). This information is essential if we want to react to current parameters in a smart home, such as activating additional cooling or controlling a socket with a various load.

Voice control of the houseRating: 60%

In this article, we will connect the Amazon Echo Dot voice assistant with open source home automation. We won't be using OpenHAB Cloud, so everything runs locally. In this case, a few additional settings are necessary, but the result is worth it!

In this series, we will look at the step-by-step setup of MikroTik devices for home users or a small business (up to 25 people). In the first article, we will focus on the initial setup - we will download Winbox and set up DHCP for the primary network and guest network. Similarly, we will also adjust the WiFi settings.

Alarm from existing PIR sensors in a smart home.Rating: 0%

In a your smart home, PIR sensors may not only be used to switch lights on and off based on motion, it is possible to utilize these sensors to detect the presence of motion in a particular room. This information can be used to create a relatively reliable uncertified home security system. In this guide, you will find the logic for how this can work in the OpenHAB software in our model smart home.

NFC tags in smart homeRating: 80%

NFC (Near Field Communication) tags are small plastic or paper stickers that can be used to automate various functions in the smart home. In this article, we will show you examples of use and a guide on how to write an action on an NFC tag using a mobile phone.
