en.Installation ELV Charly
When using the "ELV-Charly" CCU DIY kit sold by ELV – consisting of a Raspberry Pi 3, the RPI-RF-MOD radio module and a case – the initial installation of OpenCCU is performed as follows.
- A completely assembled ELV-Charly.
- A microSD card with at least 8 GB. The 4 GB card possibly included with the kit is no longer sufficient since version 3.87.6.20260509.
- A computer with a card reader and the Raspberry Pi Imager.
- The choice of the release variant: regular OpenCCU or OpenCCU-LTS. For OpenCCU-LTS, download the
OpenCCU-LTS-*-rpi3.ziparchive from the OpenCCU-LTS Releases and select it in the Raspberry Pi Imager via "Use custom".
-
Install the Raspberry Pi Imager Before OpenCCU can be written to a microSD card, install the latest Raspberry Pi Imager for the operating system you use: https://www.raspberrypi.com/software/
-
Select the device After starting the Imager, select "Raspberry Pi 3" as the device.
-
Select OpenCCU As the operating system, select the "OpenCCU" entry under "Other specific-purpose OS → Home assistants and home automation" and then the image matching the Raspberry Pi 3.
-
Select the installation medium Connect the microSD card to the computer using a card reader and select it as the storage medium in the Imager.
-
Write the image Write the selected image to the card (all data on the card will be erased). Offered customizations of the operating system (user, WLAN, etc.) are not used by OpenCCU and can be skipped.
-
Insert the microSD card Insert the prepared card into the microSD card slot provided for the ELV-Charly.
-
Mount the radio module After soldering, plug the
RPI-RF-MODradio module onto the GPIO header and close the case. -
Put into operation Connect the ELV-Charly to the local network via a network cable and connect the plug-in power supply to the radio module.
-
Observe the startup The ELV-Charly starts automatically. The red LED on the front side as well as the yellow LED on the top flash at regular intervals and indicate the startup. The first start may take a little longer.
-
Startup completed As soon as the green LED on the front side flashes at a regular frequency, the system has started up properly.
-
Connect to the WebUI Open
http://openccu/in your browser (alternatively, use the IP address assigned via DHCP) to open the OpenCCU WebUI. Afterwards, the first steps after installation help with the further setup.
Updates are performed via the update function of the WebUI or manually with the *-rpi3.zip archive.
Information on uninstallation can be found under Uninstallation.
