I’m playing around with OH for several weeks now just testing a lot. and reading a lot on forums. But one thing I cannot find is the following.
I want to use a Raspberry Pi 3B+ with a RPI 7" Touchscreen to run OH and show the HabPanel at the same time. At this moment I’ve got two RPI’s running, one 'server 'with OH and one ‘client’ with the 7"Touchscreen connected showing the HabPanel. But I would like to go to the setup with just one, doing both OH and HABPanel. Can someone point me in the right direction or show me a tutorial where it’s done?
If you want to try it despite Vincent’s warnings I recommend the following.
Create a new SD card and install the standard raspbian
Configure and get the touch screen working. You could just start with your existing display.
Install openHAB using apt-get
Configure as desired.
You could even install using the openHABian Manual instructions if you prefer.
There is nothing special about openHAB or openHABian in this regard.
However, depending on how big and extensive your OH config is you will likely run into performance issues. Frankly, some of the startup times I’ve seen reported on this forum by users running on RPi 3s is already unacceptable in my book.
You also need to pay attention to power draw if the screen draws its power from the RPi instead of having its own separate power supply. The CPU will be drawing more power. Your USB dongles will be drawing more power. The RPi may not be able to power it all.
What browser will you use? I have a trimmed down chromium that’s works nicely with my 512MB oPi zero. If you don’t want to go the route of compiling your own browser, there are lots of less resource hogging browsers then chrome. Doing both OH and HabPanel on same rPi? I would suggest not to. I tried pushing an RPi with chromium-browser and simple css animations alone can basically cripple it, let alone adding OH in it.
If your home automation is “critical,” as in you have home security and stuff, I suggest you give it a dedicated hardware
I installed Chromium and Firefox and Kweb. Kweb is a little TOO stripped down and didn’t render HABPanel well. Chromium did great but didn’t scroll when a drop down extended beyond the bottom of the screen. Firefox won.
My security company (ADT) doesn’t have any kind of API, you have to use their app. Period. That used to bother me but now it is making sense. So yeah, I have both OH and HABPanel on the same device. Chromium was a bit slow but Firefox is working fine. Running on a RPi 3b+ with a 32GB SD card.
Here’s the setup so far (having problems with weather widget):
One thing I would like to do is install a screen saver that does a slideshow of photos. I can get a slideshow and I can get a screen saver but I haven’t found one that does both yet. Any suggestions?
Hey Lucky, is there a setting so that when you interrupt it, it takes you back to a specific dashboard? Right now when I stop the slideshow I’m looking at that dashboard and I’d rather go back to my main one.
