For more information see This snap is based on but has additional Raspberry Pi specific sensor libraries and a toolchain included. Node-RED listens by default on port 1880 after installation. You will have to connect all the required snap interfaces for hardware your flows will use. The snap does come with the palette editor enabled and ships the gcc toolchain as well as a bunch of development libraries so that npm can dynamically compile nodes where required when you add them via the palette editor. To see all connected and available connections please run ``` sudo snap connections node-red-rpi ``` To connect i.e. a GPIO interface (GPIO 14 here) you do ``` sudo snap connect node-red-rpi:gpio pi:bcm-gpio-14 sudo snap connect node-red-rpi:gpio-memory-control ``` Similar for i2c ``` sudo snap connect node-red-rpi:i2c pi:i2c-1 ``` When the snap is running you can view the Node-RED log using ``` journalctl -f -u snap.node-red-rpi* ``` You can also stop and restart the application by ``` snap restart node-red-rpi snap disable node-red-rpi snap enable node-red-rpi ``` The settings.js and flows.json files are located in the `/root/snap/node-red-rpi/current/` directory. ### Package name * node-red-rpi --- ### License * Apache-2.0 --- ### Last updated * 21 June 2020 - latest/stable * 23 July 2020 - latest/edge This snap hasn't been updated in a while.

They update automatically and roll back gracefully. Snaps are discoverable and installable from the [Snap Store](https://snapcraft.io/store), an app store with an audience of millions. ### Enable snapd Snap is available for [Red Hat Enterprise Linux (RHEL) 8](https://www.redhat.com/en/enterprise-linux-8) and RHEL 7, from the 7.6 release onward. The packages for RHEL 7, RHEL 8, and RHEL 9 are in each distribution’s respective [Extra Packages for Enterprise Linux](https://fedoraproject.org/wiki/EPEL) (EPEL) repository. The instructions for adding this repository diverge slightly between RHEL 7, RHEL 8 and RHEL 9, which is why they’re listed separately below. The EPEL repository can be added to **RHEL 9** with the following command: ``` sudo dnf install https://dl.fedoraproject.org/pub/epel/epel-release-latest-9.noarch.rpm sudo dnf upgrade ``` The EPEL repository can be added to **RHEL 8** with the following command: ``` sudo dnf install https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm sudo dnf upgrade ``` The EPEL repository can be added to **RHEL 7** with the following command: ``` sudo rpm -ivh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm ``` Adding the *optional* and *extras* repositories is also recommended: ``` sudo subscription-manager repos --enable "rhel-*-optional-rpms" --enable "rhel-*-extras-rpms" sudo yum update ``` Snap can now be installed as follows: ``` sudo yum install snapd ``` Once installed, the *systemd* unit that manages the main snap communication socket needs to be enabled: ``` sudo systemctl enable --now snapd.socket ``` To enable *classic* snap support, enter the following to create a symbolic link between `/var/lib/snapd/snap` and `/snap`: ``` sudo ln -s /var/lib/snapd/snap /snap ``` Either log out and back in again or restart your system to ensure snap’s paths are updated correctly. ### Install node-red-rpi To install node-red-rpi, simply use the following command: ``` sudo snap install node-red-rpi ``` ### Other popular snaps… [See more...](https://snapcraft.io/search?categories=featured) [See more in Featured](https://snapcraft.io/search?categories=featured) ### More things to do… #### [Get the snap store](https://snapcraft.io/snap-store) Browse and find snaps from the convenience of your desktop using the snap store snap. #### [Learn more about snaps](https://snapcraft.io/docs) Interested to find out more about snaps?
