In development: Download or upload emoncms feed data between local an remote emoncms server's

an should be and

Might be work making it clearer this will only work at the moment on the cloud emoncms.org not on a self hosted server to pi install.

are there any plans to make it work with the normal emoncms install to normal emoncms install?

The following errors were seen in the apache logs when sync is selected (no config)

connexion seems to be OK. sync_model.php is connecting to the remote emoncms server (an old 9.8.28 version) and all necessary params (host, username, API read key, API write key) saved into the sync table of the mariadb server
Anyway, the sync screen remains blank


With a 9.9.9 version, things are fine



@glynhudson : Can you reproduce such a bug on your side ?

Our setup is running from an emoncms (running on Pi - using pre-built SD card), configured to sync to a remote, self-hosted online emoncms.

We have managed to connect the two services together - and we can see the local and remote feeds in the list. Feeds can be uploaded to the remote, online emoncms and we see data.

If a feed name contains any white-space; the feed fails to upload. The "Local ahead of Remote by xxx" counter slowly increments.

The service-runner instructions should be updated to reflect the new service runner.

downloading a PHPFINA feed :

http://192.168.2.3/sync/download?name=temp&tag=TRH12211196_Cellule2&remoteid=56&interval=300&engine=5&datatype=1

return is :

Fatal error: Uncaught Error: Object of class stdClass could not be converted to string in /var/www/emoncms/Modules/feed/feed_model.php:126 Stack trace: #0 /var/www/emoncms/Modules/feed/feed_model.php(126): mysqli_stmt->execute() #1 /opt/emoncms/modules/sync/sync-module/sync_controller.php(152): Feed->create() #2 /var/www/emoncms/core.php(75): sync_controller() #3 /var/www/emoncms/index.php(242): controller() #4 {main} thrown in /var/www/emoncms/Modules/feed/feed_model.php on line 126

working fine with version 10.8.5 (stable)

return is success :

{"success":true}

Attempted to sync my dev laptop to my locally running emonpi.
Inputs synced ok, however the feeds section didn't show the available feeds.

The api call /sync/feed-list returned this malformed json response:

Notice: Undefined property: stdClass::$start_time in [emoncms_dir]/sync/sync-module/sync_controller.php on line 67

Hi,
there is an issue with PHP7.3 and hyphen in regex
check emoncms/emoncms#1180 for reference

sync.diff.txt

The installation instructions are not in line with the current filesystem employed.

See https://community.openenergymonitor.org/t/sync-from-emonpi-to-local-emoncms/14002

Discovered on a fresh install of Emoncms using emonScripts updated to support php8.2 on Debian 12 "bookworm". Navigating to the Sync page displays a JavaScript alert "Error - 200: OK" and does not list feeds when the connection details for another emoncms are provided.

Investigating the response for the /sync/feed-list request shows a php warning:

<br />
<b>Deprecated</b>:  Creation of dynamic property Sync::$feed is deprecated in <b>/opt/emoncms/modules/sync/sync-module/sync_model.php</b> on line <b>29</b><br />
{"enphase_panel\/Back_East_LRW":...}

If you provide a password that contains an & when connecting you get a message "username or password empty"

The remote username and password are not sanitised or encoded for posting via URL. I think this is causing the issue I am experiencing, which is that authentication fails against my remote server. My password is full of special characters that need encoded for POSTing.

According to the PHP documentation for curl_setopt's CURLOPT_POSTFIELDS setting, this post data must be URL encoded.

In general there are other places that should use encoding, e.g. here. Basically it should be used everywhere regardless of whether the data is expected to be safe or not.

See:

https://community.openenergymonitor.org/t/migrate-multigraphs-from-emoncms-org-to-local-emoncms-installation/7641/2

Implementation notes:

• requires remapping of feedid's to match new feed ids of migrated inputs
