I too am having issues with a Rpi3. After trying ‘bundle’ it seems to fail to ‘make’ postgres.

An error occurred while installing do_postgres (0.10.14), and Bundler cannot
continue.
Make sure that `gem install do_postgres -v '0.10.14'` succeeds before
bundling.
My installation is on Ubuntu but I know there are a number of others who have installed successfully on an RPi. If you go back up the thread, you will find various links to resources that some have used to get dashing working on the RPi.
EDIT: Just a quick scan of your errors seems to show that you don’t have the postgres libraries/headers. Have you installed the postgres libraries and server dev headers? You will have to install these manually as the dashing installation expects these.
If you look in the assets/javascripts/application.coffee file, you should see a line:
Dashing.widget_base_dimensions ||= [127, 140]
This defines the standard length/width of each widget and can be adjusted as per your needs. Note that you will probably have to restart dashing each time you make any changes to these, for the changes to be picked up.
Thanks @AV_HomeAuto. London has been great the last few weeks - we are actually having a nice summer for a change!
WRT the OH2 side of things, I am not actually doing much else with it. The system as it stands in the github repo is working with both 1.8 and 2.0, and so there is probably not much to be gained with another separate thread just for 2.0.
I have another Problem with my Weather widget.
I can’t get the precipitation work.
I use openweathermap.
In my default.items I have:
Number Weather_Precipitation “Precip probability [%d %%]” (All, Weather) {weather=“locationId=home, type=precipitation, property=probability”}
The first one ist my sitemap the second one the dashboard
I don’t know why there is no value for precip probability tomorrow
The icon for few-showers is missing and the first precip probability is unsivible
Unless your openHAB sitemap is showing the precipitation correctly, the dashing dashboard will not be able to display this. As your today’s precipitation is showing as 0% on the sitemap, dashing is also showing 0%. For tomorrow, your openHAB sitemap is not getting data, and so dashing will also continue to show 0%.
I’m having the same problem which you solved by the mentioned package installs. But even though I’ve now installed them I’m still not getting any further.
Could the problem be that I have conflicting versions of Ruby? I’ve read somewhere that Dashing only works with the 1.9 version of Ruby.
ls /usr/bin/ruby =>
ruby ruby1.9.1 ruby1.9.3 ruby2.1
Any suggestions on how to troubleshoot this? It seems that also @neohusky has the same problem.
I spent a few nights trying to get it working on the RPi3. Unfortunately, i hadn’t gotten it to work. I couldn’t get dashing to get passed the error I listed above despite trying to install the dependencies.
I followed the suggestion at this page. Which in short suggest to also install a server-dev package:
sudo apt-get install postgresql-server-dev-9.4
Then “bundle install” from the dashboard folder.
But I must admit that the HABPanel alternative seems a lot more straightforward and when its a bit more mature I will give it a go. And perhaps it will also be included in future Openhab releases.
Great work interfacing this UI with Openhab! This is a lot more suitable for a tablet compared to the standard OH UI.
How would I go about creating a widget containing both the temperature and the humidity? E.g. “xx.x C / yy %”. Of course then with a smaller font so that they fit in the 1x1 box.
Both the ohtemp and ohhumidity widget is available but my HTML knowledge is not enough to combine these into one widget. Some help to get me in the right direction might be enough.
There are a couple of ways of doing this. A simple way is to create a virtual item in openHAB that is formed by the combination of two other items. i.e. have a rule that triggers on the change of either item, which forms the combined item. This item can then be posted to dashing. A second option, if you are using openHAB 1.8, is to define a rule that combines the json data from the two items before posting to a suitable custom widget in dashing that supports dual items. An example of this is the Central Heating Dashboard widget update rule in the dashboard.rule file, combined with the ohheating widget.
Yes, this is definitely easier. An alternative is @igor’s Android solution, HomeHabit Dashboard - Original thread which is just an android app, and does not require anything new on the server side.
