I’m moving to a new Raspberry Pi and came across this when preparing. I’m sorry I didn’t say thank you before nachtigall!

The bundle which used to have to be downloaded to be hosted from a local web server to avoid needing to be online to use OSPi.

Anyway, if it has all changed, are there instructions on how to host/run the App component please? I’ve followed the upgrade guide but saw no mention of a separate App component sorry.

I have an OpenSprinkler Pi and wish to host the app with HTTPS/TLS.

Thank you!

Hello,

Is it still possible to host the javascript files on a local webserver with this firmware release?
Where exactly are the javascript files please? I’ve not been able to find them again (I imagine they’ve been changed?).

Thank you!

PS: Found instructions at the bottom of this repo’s readme, but the javascript bundle can’t be downloaded any longer: https://github.com/OpenSprinkler/OpenSprinkler-App

I wanted to delete my second post (above) as I had updated the first after (mostly) solving the issue.

Sadly both my posts got stuck waiting for a moderator. It seems the forum filters don’t like my habit of going back and editing posts more than once to get them just_right!

To work around the intermittent (non-fatal) errors I ended up adding the following lines to the end of my reverseproxy-ssl.conf file in apache:

# Avoid races (at the cost of performance) to re-use a pooled connection
# where the connection is closed
SetEnv proxy-nokeepalive 1
SetEnv force-proxy-request-1.0 1

Could you share some of your config please nachtigall?

Hello,
I realise the last post was some time ago, but I’m also wrestling with the same problem. I want to host my OpenSprinkler setup over HTTPS, locally on my home network.

I have configured an instance of apache2 on my Raspberry Pi to host the UI assets and reconfigured OSPi to use it (with the help of a support ticket). I have tried various reverse proxy configuration (using Apache’s mod_proxy) and now have it mostly working.

The system appears to respond, but occasionally shows a generic “Network error” in the red ticker at the bottom of the OpenSprinkler UI (the same thing which shows if you have Raid delay set). I think this is possibly a problem with the “Weather Service” due to “mixed content” loading in the Browser, but I’m still trying to figure it out.

I stumbled through the official guide as it is lacking a lot of detail but eventually got the UI assets hosted
https://openthings.freshdesk.com/support/solutions/articles/5000164006-using-a-different-server-for-ui-assets

I then wrestled with the mod_proxy configuration and got the following to *mostly* work.

Firstly I have two DNS entries for the Raspberry Pi hosting this. For these examples they are “opensprinkler.lan” and “othername.lan”. both names resolve to the same IP, that of the Raspberry PI.

I then configured Apache for a basic SSL configuration (not documented here) using self-signed certificates for now (I’ll fix this later)

Then I enabled the following two “site” config files, after extracting the OSPi assets file in to /var/www/html

This is saved as ospi-assets-ssl.conf:
`
<IfModule mod_ssl.c>
<VirtualHost *:443>
ServerName othername.lan
ServerAlias othername.lan
ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined
SSLEngine on
SSLCertificateFile /etc/ssl/certs/ssl-cert-snakeoil.pem
SSLCertificateKeyFile /etc/ssl/private/ssl-cert-snakeoil.key
<FilesMatch “\.(cgi|shtml|phtml|php)$”>
SSLOptions +StdEnvVars
</FilesMatch>
<Directory /usr/lib/cgi-bin>
SSLOptions +StdEnvVars
</Directory>
DocumentRoot /var/www/html
<Location />
Order allow,deny
Allow from all
</Location>
</VirtualHost>
</IfModule>
`

This is saved as reverseproxy-ssl.conf:
`
IfModule mod_ssl.c>
<VirtualHost _default_:443>
ServerName opensprinkler.lan
ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined
SSLEngine on
SSLCertificateFile /etc/ssl/certs/ssl-cert-snakeoil.pem
SSLCertificateKeyFile /etc/ssl/private/ssl-cert-snakeoil.key
<FilesMatch “\.(cgi|shtml|phtml|php)$”>
SSLOptions +StdEnvVars
</FilesMatch>
<Directory /usr/lib/cgi-bin>
SSLOptions +StdEnvVars
</Directory>
ProxyRequests Off
<Proxy *>
Order deny,allow
Allow from all
</Proxy>
ProxyPass / http://127.0.0.1:8008/
ProxyPassReverse / http://127.0.0.1:8008/
<Location />
Order allow,deny
Allow from all
</Location>
</VirtualHost>
</IfModule>
`
Then reloaded apache and tested.

I then configured my OpenSprinkler to use Javascript assets from https://othersite.lan/js . I had to do this by going to http://opensprinkler.lan:8008 (the insecure port I have OpenSprinkler run on) and I followed the instructions in the guide linked at the top of this post to change the JavaScript URL there.

As mentioned this *mostly* works. Occasional network errors occur but the interface otherwise seems to work.

Thanks Ray,

I already have something running on the port so was looking to configure OpenSprinkler before using it!

I’ll stop the other service and try OpenSprinkler on it’s own so I can see the option you’re talking about.

Thank you

Hi Ray,

Thank you for confirming this is possible. I’m a new user, so how can I change the port? Is there a way to configure the port using a variable or do I have to modify the code before building it?

Thank you in advance!

Hello,
I’m also looking for a flow meter, but the only two-wire “pulse output water meter” I can find are on eBay and usually cost much more than AU$77. Most have a display, but I don’t need that – just digital output to my OSPI.

I came across much cheaper Hall Effect Flow Meters, but all of the 3/4″ ones are 3-wire. Would these work at all please?

This one appears to be a pulse output “turbine” with 3 wires.

Thank you in advance!
