Kivy Reef: A touchscreen interface for reef-pi - Announcements and Discussion thread

[NXE]

Ok so weird story, I went ahead and retried it now and t hings are working. Another thing was that the other day I was having trouble being able to see the options to change color and range for the graphs in reef-pi and that is now working again too, so my guess is that there was an issue with reef-pi not with kivy.

Great, glad it's working for you now.

Will this work with Robo-tank?

Will this work with Robo-tank?

Yes, it will work with any hardware running reef-pi. I am using it with a Robo-tank board.

I noticed that on the install instructions it says "Note that kivy-reef will need to be started from a local console (not via ssh) or a systemd service."
I have tried a few times to create a system service to start this on boot but it fails every time.
I even tried running the service after boot but I get the same errors.
Any tips to get this working?

Hello looking for some additional assistance. I installed Kivy-reef directly on my reef-pi because I was not able to get the systemd service working but when I start it I get an error. But I only get the error when the config is pointed to itself (http://127.0.0.1) When I point it to another location, working or not it runs.
Error output as follows:

Hi @NXE or anyone else, can we get a step-by-step on how to install this? It looks awesome. But I am a complete noob.

best and thx

 

[Wolfw28]

I would like to know also

 

[NXE]

Hi @drnibz @Wolfw28 , apologies for the delayed response – I have not had much time for Kivy Reef lately. Installation instructions are provided on the github page: https://github.com/natbird/kivy-reef#instructions

You will need to download and extract the Kivy Reef files (https://github.com/natbird/kivy-reef/archive/refs/heads/main.zip) and install the necessary dependencies, then run Kivy Reef and edit the configuration file.

I do intend to bundle Kivy Reef into a package for easier installation at some point, but don't have time at the moment unfortunately.

 

[SilverBulletPRN]

This looks great, I can't wait to for my replacement rpi to come and mess around with this

 

[astreck827]

Can this be run with the Zero 2 W or does it have to be on a 3 or 4?

 

[NXE]

I haven't tested it, but Kivy-Reef should run on this board.

 

[InactiveAcct]

@NXE is this compatible ReefPi 6.0?

 

[Des Westcott]

I really like the look of this.

I've just installed a 7" Waveshare touchscreen on my Robo-Tank/Reef-Pi running 6.0. I have also set it up to run in kiosk mode so as to not to have the GUI stuff competing for screen space. BUT, the on-screen buttons are a bit too small for my fat fingers - a problem this Kivy-Reef interface seems to resolve.

I have had a look at this page https://github.com/natbird/kivy-reef#instructions

Is the setup as straightforward as following the guides in the order listed?

I have been running Reef-Pi for quite a few years now, but am useless with the software / Linux side of it. I'm OK with the hardware side though.

Hi @DanTheReefer – yes, KivyReef is compatible with reefpi 6.0. But let me know if you run into any issues.

Hi @Des Westcott – It is not as straightforward as I would like, but the basic steps are:
1. Download the code from GitHub (either run 'git clone https://github.com/natbird/kivy-reef.git' or download as a zip from the website and extract).
2. In the folder in which kivyreef was cloned/extracted, run 'pip install -r requirements.txt' (you may need to use pip3 install -r requirements.txt depending on your distribution).
3. Once all of the dependencies are installed, run 'python3 main.py' from the same folder. This will start kivyreef.
4. The first time kivyreef is run it creates a file called 'kivyreef.ini' which stores the program settings. If you are running kivyreef on the same machine as reefpi and have not changed the username/password for reefpi, the default settings should be fine.
5. To autostart kivyreef, you can follow the link in this post: https://www.reef2reef.com/threads/k...nts-and-discussion-thread.865824/post-9487165

Let me know if you have any issues and I will do my best to assist.

I am working on a new version of kivyreef that will also work on Android phones/tablets and hopefully make the installation process more straightforward, but progress is very slow unfortunately as my spare time is limited these days.
