Migration (V4.2->V4.3)

Essential Changes

Graphs in the WebFront

The graphs in the WebFront were completely redone and are creates directly by the IP-Symcon Server. This results in a WebFront that is ~15% smaller and thus loads faster via internet. The presentation was improved as well and avoids constant S curves when possible.

Bool Graphs

Graphs in the Mobile Apps

The mobile apps support all options for graphs like dynamic scaling, high density, or the presentation of extrema. Multi-graphs are also supported and the evaluation can be done directly on the mobile device.

Mobile Bool Graphs

CSV Export in the WebFront

The CSV export supports multi-graphs and presents the individual datasets one after the other. The name, date, time, and aggregation level are shown. The data is in a Microsoft Excel compatible format and can be copied directly.

Better Support of Devices

  • Module for EnOcean D2-01-*, D2-06-*
  • Module for Eltako FGW14
  • Module for LCN Display and LCN RGBW

Improvements for PHP Modules

  • Any strings within modules can be translated
  • Modules check for compatibility before the updaten
  • Modules can remove local changes automatically after an update

(The use of the WebFront editor requires at least the edition IP-Symcon Professional. All other functions are included in the Basic, Professional, and Unlimited editions of IP-Symcon und can be obtained with a valid subscription. It is not required to purchase an specific “Upgrade”. If your subscription has expired, you can simply renew it and update to version 4.3 without additional costs. Please regard that push notifications and the Symcon Connect service require a connection to the internet and a valid subscription. (Shop))


Please create a backup of your complete IP-Symcon folder. Thus, you can switch back to version 4.2 if problems occur with version 4.3

If you update from version 3.4, please read the migration tutorial to version 4.0: Migration to Version 4.0, version 4.1: Migration to Version 4.1, and version 4.2: Migration to Version 4.2.

  • The 32-bit version for Microsoft Windows will be discontinued with IP-Symcon 5.0, which will be released 2018.
  • The 64-bit version is automatically installed if possible.

Migration (for PHP Module Developers)

  • The function Invalid Link: Translate should be used for translations as of now.
